    What is Logistics Management? The objective is to plan and coordinate all the activities

    necessary to achieve desired level of delivered service

    and quality at lowest possible cost.

    The scope of logistics include the entire gamut of

    activities starting from the procurement and management

    of raw materials through to delivery of final product to

    the customer.

    The ultimate purpose of any logistics system is to satisfy

    the customer by establishing linkages of people at all

    levels in the organization directly or indirectly to the

    market place.

    As it is getting increasingly difficult to maintain a

    competitive edge through product alone, customer

    service has started to provide the distinctive

    difference between one companys offer and that of

    its competitors.

    The underlying concept is The process of

    strategically managing the procurement, movement

    and storage of materials, parts and finished inventory

    and the related information flows through the

    organization and its marketing channels in such a

    way that the current and future profitability are

    maximized through the cost effective fulfillment of

    orders.

    haracterized by low cost of production due togreater sales volume, economies of scale enabling

    fixed costs to be spread over a greater volume and

    the impact of the experience curve.

    Value advantage is in terms of product offering adifferential plus over competitive offerings.

    - Based on marketing concept that customers that

    customers don't buy products, they buy benefits.

    - Benefits may be intangibles and may not relate tospecific product features.

    - It can be an image or reputation or even some

    functional aspects.

    Adding value through differentiation is

    extremely powerful means of achievingcompetitive edge in the market.

    One of the significant method of adding

    value is service.

    Service helps in developing relationship with

    the customers through provision of an

    augmented offer.

    Augmentation takes many forms such asdelivery services, after-sales services,

    financial packages, technical support etc.

    Primary activities represent the functional

    areas like arranging inputs for transformingthem into output, and managing distribution,

    marketing, sales, and services.

    The secondary activities facilitate the

    integration of all the functions across the

    entire organization.

    The companies can achieve competitive

    advantage and create differentiation byorganizing and performing these activities

    more efficiently or in a unique manner than

    their competitors.

    How do we define logistics

    management?

    A process of satisfying customer needs through

    coordination of materials and information flows that

    extend from the market through the firms operationand beyond that to the suppliers.

    A shift to an integrated orientation from the

    conventional manufacturing or marketing

    orientation.

    Traditionally, manufacturing and marketing have

    been considered as separate activities each having

    different priorities.

    Manufacturing priorities and objectives areconcerned with achieving operating efficiencies

    based on long production runs, minimized set upsand changeovers, and product standardization.

    Marketing priorities and objectives are concernedwith achieving competitive advantage based on

    varieties, high service levels, and frequent productchanges.

    Customer orientation and cost competitiveness has been integrated by introducing flexiblemanufacturing systems, practicing inventory

    management policies based on manufacturingrequirement planning and just-in-time inventorypolicy, laying sustained emphasis on quality andintegrating supply side issues in strategic plans.

    Is Supply chain management

    same as vertical integration?

    SCM is not the same as vertical integration.

    Vertical integration implies ownership of upstream

    suppliers and downstream customers.

    Earlier, vertical integration used to be the desirable

    strategy but increasingly the companies are focusing

    on their core business i.e. the activities that they do

    really well and where they have a differentialadvantage.

    Everything else is outsourced.

    How does Logistics differ from

    SCM? Logistics management is primarily concerned with

    optimizing flows within the organization.

    Supply chain management deals with integration ofall partners in the value chain.

    Logistics is essentially a framework that creates asingle plan for flow of products and informationthrough a business.

    Supply chain builds upon this framework and seeksto achieve linkage and coordination between processes of other entities in the pipeline i.e.suppliers and customers, and organization itself.

    Activities Included in Logistics

    Logistics competency is achieved by

    coordinating the following functional areas.

    - Network design

    - Information

    - Transportation

    - Inventory

    - Warehousing, material handling andpackaging.

    Network Design

    Network design is the prime responsibility oflogistics managers since a firm facilities andstructure is used to provide products and materialsto the customers.

    Logistics facilities typically include manufacturingplants, warehouses, cross-dock operations, and retailstores.

    Determining the number and type of facilityrequired, their geographic locations, and the work to

    be performed at each is an important part of networkdesign.

    In certain situations, some of the facility operationsmay be outsourced to service specialists.

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    27/383

    27

    Network design determines the type of the

    inventory and the quantity to be stocked at eachfacility, and the assigning of customer orders

    for shipment.

    Network of facilities also includes information

    and transportation as a part of entire structurefrom where logistical operations such as

    processing of customer orders, maintaining

    inventory and material handling are performed. The network design must consider

    geographical variations.

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    28/383

    28

    The factors influencing modifications of

    network design are:(a) Change in demand and supply

    (b) Product assortments

    (c) Changes in suppliers source of supplies.

    (d) Manufacturing requirements.

    The first step towards achieving competitiveadvantage lies in superior network design,

    as the real competition is not between twocompanies but between efficiency andeffectiveness in managing their supply chainnetwork.

    - Internal customers are organizational units

    within a firm that require logistical supportto perform their designated work.

    (c)The process of order management involves

    - Receipt of an initial order

    - Invoicing- Delivery, and

    - Collection.

    Incorrect information and delays in order processing can cripple the logisticsperformance; thus quality and timeliness arethe key issues in logistical operations.

    Transportation

    Transportation is the operational area oflogistics that geographically positions theinventory i.e. provides for place utility.

    Companies accomplish transportation inthree different ways:

    (a) A private fleet of vehicles may be operated.

    (b) Contracts may be entered into with

    transport companies.(c) The service of different transport

    companies may be engaged on anindividual shipment basis.

    A. Cost of transportation

    - The payment for movement between two

    geographical locations and expenses related to

    administration and and maintaining in-transit

    inventory.

    B.S

    peed of transportation- The time required to complete a specific

    movement.

    - Transport firms capable of providing faster

    services normally charge higher rate.- The faster the transportation services, shorter is

    the time interval during which the inventory is in

    transit and unvailable.

    35/383

    35

    C. Consistency of transportation

    - Refers to variations in time required toperform a specific movement over a number

    of shipments.

    - Consistency is a measure of dependability of

    transportation.

    - Inconsistency in transportation leads to

    inventory safety stocks required to protect

    against unpredictable service breakdowns.

    jS peed and consistency combine to create

    quality aspect of transportation.

    Inventory

    The objective is to achieve the desired

    customer service with minimum inventory

    commitment, consistent with lowest total cost.

    Excessive inventories may be helpful incompensating for deficiencies in network

    design but ultimately result into higher total

    logistics cost.

    The best practice of inventory management is

    to achieve maximum turnover while satisfying

    customer commitments.

    Warehousing, Material Handling,

    And Packaging Merchandise needs to be warehoused at selected

    times, transport vehicles material handling for

    efficient loading and unloading and goods are mostefficiently handled when packaged together into

    shipping cartons or other type of containers.

    The logistical activities carried out in warehouse are

    sorting, sequencing, order selection, transportconsolidation and sometimes product modification

    and assembly.

    38/383

    38

    Within the warehouse, products must be

    received, moved, sorted, and assembled tomeet customer order requirements and for

    these activities material handling becomes

    significant.

    Products packed in cans, bottles or boxes are

    handled more efficiently when combined into

    larger units such as MasterCartons.

    Master units can further be consolidated intolarge units such as pallets, containers etc.

    Inventory Management Policy The following factors are required to be

    considered while formulating inventory

    management policy.

    - Customer segmentation

    - Product requirements

    - Transport integration

    - Time-based requirements

    - Competitive performance.

    Thus, it may be desirable to hold slow-moving

    or low profit items at a central distributionwarehouse whereas core customers may be

    served by fast, reliable air services.

    Orders to fringe customers may be delivered

    by less expensive ground transportation.

    Transport Integration

    A sound inventory management strategy

    would be to stock sufficient products at

    warehouse to be able to arrange consolidated

    shipments to a customer or a geographic area. The corresponding savings in transportation

    may more than offset the increased cost of

    holding the inventory.

    44

    Time-Based Requirements Time-based arrangements reduce the overallinventories by developing the capability to respondrapidly to exact to exact manufacturing or retail

    customers. If the products/materials can be delivered quickly, itmay not be necessary to maintain inventories atmanufacturing plants/ retail stores.

    If replenishment can be achieved rapidly less safetystock will be required and instead of stockpiling andholding safety stock the requirement will be toreceive the exact quantity of inventory at the timerequired.

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    45/383

    45

    Time-based programmes tend to reduce

    shipment sizes, which in turn increases thenumber, frequency, cost of shipments and

    hence higher transportation cost.

    An effective logistical arrangement will be to

    achieve a trade-off resulting into desired

    customer service at the lowest total cost.

    Movement and storage of product, materials, andsemi-finished parts and components betweenenterprise facilities represent the responsibility ofmanufacturing support logistics.

    In context of wholesale & retail trade, it implies

    selection of assortment of inventory to be moved tothe next level of value chain.

    Basically, supports what, where and when of theproduction and not how.

    Procurement performance cycles are

    invariably longer excepting in those cases

    where the value of material or component may justify paying higher freight rates for faster

    inbound transport.

    A critical issue in procurement is uncertainty

    Inventory decisions-High risk &

    high cost Without the proper inventory assortment, marketing

    may find that sales are lost and customer satisfactiondeclining.

    Overstocks increase cost and reduce profitability

    through added warehousing, working capitalrequirements, deterioration, insurance, andobsolescence.

    As the significance percentage of assets are inventoryrelated, a reduction of firms inventory by a fewpercentage points can lead to dramatic improvementin profits.

    ROI= (Profit/ Fixed assets +Current assets)

    Substantial improvement in the productivity ofinventory can be achieved by re-engineering

    supply chain processes. Poor inventory management may lead to stock

    outs and hence cancellation of customersorders, overstocking leading to insufficientstorage space and increase in the number andrupee value of obsolete products.

    Consequently, inventory management has a

    large financial impact on the firm. Investments blocked in inventory cannot beused to obtain other goods or assets that couldimprove the enterprise performance.

    Types of Inventory Broadly there are three types of inventory

    - Manufacturing inventory

    - Wholesale inventory

    - Retail inventory

    (a) Manufacturing inventory- Manufacturers inventory commitment starts with

    raw material and component parts, including work-in-process, and ends with finished goods.

    - Manufacturer needs to transfer the finished goodsinventory to warehouses in closer proximity towholesalers and retailers.

    - Manufacturers inventory commitment is relativelydeep and has long duration.

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    73/383

    73

    (b) Wholesale inventory

    - Wholesaler purchases large quantities from

    manufacturers and sells small quantities to retailers inorder to provide retail customers with assorted

    merchandise from different manufacturers in smaller

    quantities.

    - Thus wholesaler risk exposure is narrower but deeperand of longer duration than that of retailers.

    - In case of seasonal goods, the wholesaler is forced to

    commit inventory, far in advance of selling, thus

    increasing the depth and duration of risk.

    - The current trend of expansion of product lines has

    increased the width of inventory risk.

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    74/383

    74

    (c) Retail inventory

    - Retailer inventory risk is wide but not deep.

    - The emphasis is more on inventory velocity.

    - Inventory velocity is measured by inventory turnover.

    - The risk is undertaken on variety of products but for a

    given product the risk is not deep relatively. Theexception is specialty retailer where the depth and

    duration will be longer as they handle narrower lines.

    - For instance, retailers risk is spread across more than

    10,000SKU

    s, a general merchandise and food storemay carry around 25,000 SKUs and a full line

    department store may have as many as 50,000 SKUs.

    Functions underlying inventory

    commitmentsA. Geographical Specialization

    - It allows for geographical specialization forindividual operating units.

    - The need for geographical specialization arisesbecause various factors of production viz. power,materials, water, labour, manufacturing facilities arelocated at a considerable distance from the majormarkets.

    - For instance, tyres, batteries, transmissionequipments and springs for an automobileassembly. The production facilities for each of thethese are traditionally located near the source ofmaterials to minimize transportation cost.

    77/383

    77

    B. Decoupling

    - Provides for increasing operating efficiency within a

    single manufacturing facility by stockpiling work-in-process inventory between production operations.

    - Decoupling enables manufacturing and distribution ofeconomic lot sizes in anticipation of sales thusensuring large sized shipments with minimum freightcost.

    - Decoupling permits products manufactured over aperiod of time to be sold as an assortment.

    - Decoupling increases the operating efficiency at a

    single location while geographical specializationincludes multiple locations.

    - However, JIT,DRP etc have reduced the economicbenefits of decoupling considerably.

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    78/383

    78

    C. Balancing Supply and Demand

    - Balancing is concerned with elapsed time between

    consumption and manufacturing as balancinginventory reconciles supply availability with demand.

    - Particularly useful in linking variations ofconsumption with manufacturing in case of seasonal

    products.- Balancing seasonal production and year round

    consumption such as orange juice or year roundproduction and seasonal consumption of blankets orknitting wool.

    - In case of sort selling season, manufacturers,wholesalers and retailers are forced to take aninventory position far in advance of peak sellingseason.

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    79/383

    79

    - From retailers perspective, an inventory position isplanned six months prior to the peak selling period.

    - The main function of balancing supply and demandis to ensure that investment in stocks is liquidatedcompletely within the season.

    D. BufferUncertainties

    - Safety stock protects against two types ofuncertainties:

    - (a) Demand in excess of forecast during theperformance cycle. For instance, customers request

    of more or less units than planned.- Delays in the performance-cycle length itself. For

    instance, delay in order receipt, order processing, ortransportation.

    Inventory ManagementS

    trategy Companies can postpone positioning of inventory

    by maintaining stock at the plants or they may

    decide to place more products in local distribution

    centres to have it closer to the market.(a) Manage inventory at each distribution centre

    independently.

    (b) Consider inventory interdependence across

    distribution sites by managing inventory centrally.

    (c) Ensure more coordination and communication in

    case of centralized inventory management.

    Inventory Cost Consideration1. Origin purchase consideration

    2. Transportation cost.

    (a) Origin purchase means the buyer is responsible forfreight cost and product risk when the product is intransit.

    (b) Depending on the delivery terms, the buyerassumes full risk on inventory at the time ofshipment.

    (c) Depending on the payment terms, transit inventory

    would be a part of enterprise's average inventoryand therefore subject to an appropriate charge.

    (d) Transportation cost must be added to purchaseprice to obtain an accurate assessment of the value

    of goods tied up in inventory.

    The following are considered in perpetual

    review:

    - On hand inventory represents quantity that is

    physically present in the particular distribution

    facility.

    - On-order inventory represents quantities thathave been ordered from suppliers.

    - If on-hand plus on-order quantity is less than

    or equal to the established reorder point,inventory control process will initiate another

    replenishment order.

    Periodic Review

    The inventory status is reviewed at regular intervalssuch as weekly or monthly.

    The re-order point is adjusted to consider theextended intervals between reviews.

    The formula for calculating the periodic reviewreorder point is

    jROP= D( T + P/2) +SS, where

    - ROP= re-order point

    - D=average daily demand- T= average performance cycle length

    - P=review period in days

    - SS= safety stock

    jDS = (A +7 Ij ) / 7 Dj , where

    - DS

    = no. of days supply for distributioncentre inventories.

    - A= inventory units to be allocated from the

    warehouse

    - Ij= inventory in units for distribution centre j.

    - Dj = daily demand for distribution centre j

    jIn the above example,

    DS = {500 + ( 50+100+75)} / (10+50+ 15)

    DS= {500 + 225} /75 =725/75 = 9.67 days

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    93/383

    93

    Thus, fair share allocation means that eachdistribution centre should be brought up to 9.67 days

    stock. The amount to be allocated to each distribution

    centre is determined as under:

    jAj = (DS Ij /Dj ) x Dj, where

    - Aj = amount allocated to distribution centre j- DS= number of days supply that each distribution

    centre is brought upto.

    - Ij = inventory in units for distribution centre j

    - Dj= daily demand for distribution centre j- Thus, the amount allocated to distribution centre 1

    will be

    jA1= (9.67- 50/10) x 10 = (9.67- 5) x 10= 4.67x 10=46

    DRP/MRP system integrates finished goods, work-in-process, and materials planning.

    DRP provides a schedule for eachSKU

    and eachdistribution facility.

    For each planning period, the schedule will report thefollowing:

    - Gross requirements reflecting demand from customersbeing catered to by different distribution facilities.

    - Scheduled receipts i.e.replenishment shipmentsplanned for arrival at the distribution centre.

    - Anticipated week ending total deliveries.

    - Projected on-hand inventory i.e. prior weeks on-handinventory- current weeks gross requirement +scheduled receipts.

    Benefits of DRP

    Improved service levels by increasing on timedeliveries and decreasing customer complaints.

    Better planning of new product launches.

    Improved ability to anticipate shortages so that

    marketing efforts are not expended on products withlow stock.

    Reduced distribution centre freight costs resultingfrom coordinated shipments.

    Improved inventory visibility and coordinationbetween logistics and manufacturing.

    Reduced warehousing space requirements because ofinventory reductions.

    Demand Forecasting

    Forecasting process comprises of twoelements

    (a) Nature of demand, and

    (b) Forecast components

    Nature of Demand

    Dependent demand Independent demand

    Dependent versus Independent

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    101/383

    101

    Dependent versus Independent

    Demand Vertical dependent is characterized by

    sequence of purchasing and manufacturing,such as number of tyres used for assembly

    of automobiles. Horizontal dependent occurs in a situation

    where an attachment, promotion item oroperators manual is included with each item

    shipped.

    (a) The demanded item may not be required tocomplete the manufacturing process but may

    be needed to complete the marketing process.

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    102/383

    102

    (b) Once manufacturing plan for base item is

    determined , requirements of components/

    attachments can be calculated directly and noseparate forecasting is done.

    Independent demands are ones that are not related

    to the demand for another item.

    For instance, demand for refrigerator is not relatedto the demand for milk.

    Independent demand items are forecasted

    individually.

    1. Base demand

    2. Seasonal factors

    3. Trends

    4. Cyclic factors

    5. Promotions

    6. Irregular quantities.

    Mathematically forecast is expressed as

    jFt+1= (Bt x St x Tt x Ct x Pt) + I, where

    - Ft+1= forecast quantity for period t+1

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    104/383

    104

    - Bt= base level sales demand (average sales level)for period t+1

    - St= seasonal factor for period t- T= trend component (quantity increase or decrease

    per time period)

    - Ct= cyclic factor for period t

    - Pt= promotional factor for period t- I= irregular or random quantity.

    j All forecasts may not include all components.

    A. Base demand is based on average demand over an

    extended period of time.(a) There is no seasonality, trend, cyclic or

    promotional component.

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    105/383

    105

    B. Seasonal component is characterized by upwardand downward movement in demand pattern,

    usually on annual basis e.g. emand for woollen blankets is at peak during winter months andlowest during summer.

    (a) Seasonality at wholesale level precedes consumerdemand by approximately one quarter.

    (b) An individual seasonality factor of 1.2 indicatesthat sales are projected at 20% higher than anaverage period.

    C. Trend Component exhibits long range movement in

    sales over an extended period of time.

    (a) Trend may change number of times over the entireproduct life cycle.

    Assume the firm has an aggregate monthly

    forecast for the entire country as 10,000 units

    and it use four distribution centres to service thedemand with a historical split of40, 30, 20, and

    10 per cent respectively.

    Forecasts for individual distribution centres willbe projected to be 4,000, 3000, 2,000 and 1,000

    respectively.

    In top-down approach a national level SKU

    forecast is developed and then the forecasted

    volume is spread across locations on the basis

    of historical sales pattern.

    B. Bottom-up Approach

    Decentralized approach since each distribution

    centre forecast is developed independently.

    Results into more accurate forecast as it tracks

    and considers demand fluctuations within

    specific markets. Requires more detailed record keeping and is

    more difficult to incorporate demand factors

    such as impact of promotion.jTrade-off the detail tracking of bottom-up

    approach with data manipulation ease of top-

    Transportation Transportation decisions are more strategic ones

    closely linked with inventory decisions.

    Decisions are based on trade-off between the cost of

    using a particular mode of transport with the cost ofinventory associated with that mode.

    For instance, air shipments may be fast, reliable , and

    warrant less safety stocks; they are expensive whereas

    shipping by sea or rail may be much cheaper but theynecessitate holding relatively large amount of

    inventory to protect against the inherent uncertainty

    associated with them.

    115/383

    115

    Customer service levels and geographic

    locations are important aspects in transportation

    decisions. Transportation accounts for roughly 30% of the

    logistics costs and therefore operating

    efficiencies become important aspects . Shipment sizes i.e. consolidated bulk shipments

    versus smaller lot sizes; routing and scheduling

    of vehicles become important part of

    companys transport strategy.

    Transportation is one of the most visible

    elements in the logistics operation.

    - Primary function is the movement up and down thevalue chain.

    - As transportation uses temporal, financial andenvironmental resources, the movement of materialsshould take place only when it enhances the productvalue.

    (a) Uses temporal resources because the product isinaccessible while in transit.

    - Due to JIT strategies transit inventories are becoming more significant thereby reducing

    manufacturing and distribution centre inventories.(b) Expenses incurred internally for private fleet of

    vehicles or externally for commercial or publictransportation constitute financial resources.

    (c) Transportation consumes fuel and oil and also

    B. Product Storage

    - Temporary storage through vehicles becomes

    expensive as in-transit storage is required to be

    moved again in a short duration of time.

    - Sometimes temporary storage becomes

    advantageous as the cost of unloading andreloading the product in a warehouse may

    exceed the daily charge of storage in

    transportation vehicles.

    - Many times where the warehouse space is

    limited, utilizing transportation vehicles

    becomes a viable option.

    120/383

    120

    The options available to a transporter in case of

    warehouse space constraints are

    (a) Instruct driver to take a circuitous or indirect routeto its destination, as the transit time would be

    greater as compared to direct route. Thus transport

    vehicle is used as temporary storage option.

    (b) Change the shipment destination i.e. temporarystorage is achieved through diversion.

    - For instance, product that is, say, scheduled initially

    from Mumbai to Hyderabad gets diverted mid way

    to Vishakapatnam (Vizag) as Vizag warehouse maybe in greater need of product and has the storage

    capacity.

    121

    - Traditionally, the telephone was used to direct

    diversion but nowadays satellite

    communications between headquarters and

    vehicle handle such tasks more efficiently.

    - Though product storage in vehicles can be

    costly, it can be justified from a total cost perspective when loading, unloading costs,or

    capacity constraints are considered.

    123/383

    123

    A. Economies ofScale

    Transportation cost per unit of weight decreases

    when the size of the shipment increases i.e.

    shipments that utilize the entire vehicles

    capacity like truck load (TL) cost less per kg

    than less than truck load (LTL) shipments. Fixed costs in transportation include

    administrative costs of taking transportation

    order, time to position the vehicle for loading or

    unloading, invoicing and equipment cost.

    It costs as much to administer a shipment of 1

    kg as it does to administer a 1000 kg shipment.

    B. Economies of Distance

    124/383

    124

    B. Economies of Distance

    Transportation cost per unit of distance

    increases at a decreasing rate as distanceincreases. Also called Tapering Principle

    For instance, a shipment covering a distance of

    800 kilometers will cost less than twoshipments of same combined weight covering

    400 kms.

    Fixed expenses incurred to load and unload the

    vehicle get spread over more kilometers

    resulting in lower overall per kilometer charges.

    - Cost curve increases at a decreasing rate as afunction of distance and is known as tapering

    principle.- Cost curve does not begin at the origin because of

    the fixed costs associated with shipment pick up anddelivery regardless of distance.

    - Tapering effect comes into existence, as the longermovements tend to have a higher percentage of inter-city rather than urban kilometers.

    - Frequent intermediate stops, typical of urbankilometers, and additional loading and unloading addto the costs.

    - Inter-city miles are less expensive since moredistance is covered with same fuel as a result ofhigher speed.

    C. Density

    - Transportation cost per unit declines as productdensity increases.

    - In terms of weight and space, an individual vehicle isconstrained more by space than by weight. Once isthe vehicle is full, it is not possible to increase theamount carried even if the product is lightweight.

    Multimodal Transport System

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    146/383

    146

    Multimodal or Intermodal transport refers to journeys that involve two or more different

    modes of transport.

    For instance, if materials are moved from

    Lanchow in central China to Warsaw in Poland

    goods may be loaded on to trucks, transferring

    them onto rails for a journey across China to

    Shanghai, then ship to Rotterdam, back intorails to cross Europe, then truck for local

    delivery.

    For Logistics managers intermodal services become

    necessar beca se of their characteristics and costs

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    147/383

    147

    necessary because of their characteristics and costs.

    For example, limited accessibility of air transportrequires coordination with a land carrier to make the

    pick ups and deliveries.

    Similarly, inaccessibility applies to rail, water and

    pipeline but not to the motor which has a definiteadvantage here.

    The intermodal services maximizes the primary

    advantages inherent in the combined modes and

    minimize their disadvantages. The combined services will have both good and bad

    aspects of the utilized modes.

    For instance, coordinate of rail and water willh l l h ll il

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    148/383

    148

    have a lower total cost than an all-rail

    movement but higher cost than that of all-water. Likewise, combined system transit time will be

    lower than all water movement but higher thanall-rail.

    The decision to use multi-modal system mustconsider the effect on total logistics costs.

    The aim of intermodal transport is to combinethe benefits of several separate modes but avoidthe disadvantages of each, like, combining thelow cost of shipping with flexibility of the road,or getting the speed of air with the cost of road.

    However, each transfer between modes causes

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    149/383

    149

    delays and adds costs of extra handling.

    Intermodal transport works well when transfer

    can be done efficiently.

    Transfer of motor carrier trailer to another

    transport mode is facilitated throughcontainerization.

    150/383

    150

    Choice of Mode Factors influencing the choice of mode are as under:

    - Bulkiness of the materials; heavy items would beshipped by ocean going vessels.

    - Value of materials; expensive items raise inventorycosts and thus encourage faster modes.

    - Criticality of materials; even low unit value items thathold up the operations need fast and reliable transport.

    - Susceptibility to market changes; operations that

    respond quickly to changes cannot wait for criticalsupplies using slower transport.

    - Reliability with consistent delivery is important.

    ontainer is large rectangular box into which a firmplaces commodities to be shipped.

    After initial loading, the commodities themselves are not

    rehandled until they are unloaded at their final

    destinations. Throughout the movement, the carrier handles the

    container, not the commodities.

    The shipper can transfer the container from one mode to

    another, eliminating the need to handle the commoditieseach time thus reducing handling costs, damage costs,

    theft, pilferage and the time required to complete the

    modal transfer.

    handling systems to include cranes, forklift

    trucks, and other equipment capable ofhandling large, heavy containers have found

    containerization to be desirable avenues for

    increasing productivity and controlling

    material handling costs, especially in periods

    of continually increasing labour costs.

    As the objective of intermodal transport

    system is to provide virtually seamlessjourney, the best way to achieve same is to use

    modular or unitized loads.

    is a specialized form of containerizationin which rail and motor transport coordinate.

    Carrier places motor carrier trailer on a rail

    flatcar, which moves the trailer by rail for long

    distance.

    A motor carrier then moves the trailer for short

    distance pickups and deliveries.

    This service combines the long-haul, low costadvantage of rail with accessibility of motor.

    The primary material handling objective is toefficiently move large quantities of inventory into

    and specific customers orders out of the warehouse.

    The functions performed in a warehouse are

    classified as movement or Handling and storage. Movement or handling is emphasized and storage is

    secondary.

    Handling is divided into

    - Receiving

    - In storage handling , and

    - Shipping

    An extremely important aspect of logistics is theproductivity potential that can be realized from

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    156/383

    156

    productivity potential that can be realized fromcapital investment in material-handlingequipment.

    S pecialized handling equipment is required forunloading bulk materials such as for solids, fluids,or gaseous materials.

    The guidelines suggested in designing the materialhandling systems are:

    (a) Equipment for handling and storage should be asstandardized as possible.

    (b) When in motion, the system should providemaximum continuous flow.

    (c) Investment should be made in handling ratherthan stationery equipment.

    (d) Handling equipment should be utilized to themaximum extent possible

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    157/383

    157

    maximum extent possible.

    (e) In selecting handling equipment, the ratio ofdeadweight to payload should be minimized.

    (f) Whenever possible, gravity flow should beincorporated in the system design.

    The handling systems can be classified asunder:

    - Mechanized

    - Semi automated- Automated, and

    - Information directed.

    Mechanized Systems

    158

    Mechanized Systems

    A. Forklift Trucks Forklift trucks can move loads of master

    cartons both horizontally and vertically.

    A pallet or slip sheet forms a platform upon

    which master cartons are stacked.

    A slip sheet is a thin sheet of solid fibre orcorrugated paper and are used for situationswhen product is handled only a few times.

    A forklift truck normally transports amaximum of two unit loads i.e. two pallets ata time

    High stacking trucks are capable of up to 40 feet ofvertical movement.

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    159/383

    159

    Even trucks capable of operating in aisles as narrow as

    56 inches ar also found in warehouses. The significance of narrow-aisle forklift trucks has

    increased as warehouses seek to increase rack storagedensity and overall storage capacity.

    Forklift trucks are not economical for long distancehorizontal movements because of high ratio of labourper unit of transfer.

    Most effectively utilized in shipping and receiving

    and placing merchandise in a predetermined storagespace.

    Common sources of power are propane gas andelectricity.

    Many forklift operations are utilizing radiofrequency data communication to speed up

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    160/383

    160

    frequency data communication to speed upload put away and retrieval assignments.

    Under the above system, workers receive theirassignments through either handheld or vehicle

    mounted RF terminals.

    RF technology provides real-timecommunication capability to central data

    processing systems, and when combined with bar code scanning of cartons and pallets,it

    allows fork lift operators to receive and updateitem status inquiry, material orders andmovement and inventory adjustments.

    Low cost, effective method of material

    handling. Highly versatile low-lift pallet and/or skid

    handlers with load capabilities from 3,000 to

    8,000 lbs.

    Typical applications include loading and

    unloading, order selection and shuttling over

    longer distances throughout the warehouse.

    Popular in grocery warehouses.

    Electricity is the power source.

    C. Towlines

    Either in floor or overhead mounted drag devices.

    The major advantage is the continuous movement butlacks flexibility of forklift trucks.

    Most common application is for order selection withinthe warehouse. Order selectors place merchandise on afour wheel trailer, which is then towed to the shipping

    dock.D. Conveyors

    Conveyors are classified according to power, gravityor roller/belt movement.

    Portable gravity style roller conveyors are often usedfor loading and unloading.

    In some cases these are transported on the over-the-road trailers to assist in unloading at the destination.

    requirements.

    j Semi automated warehouse is a mixture of

    mechanized and automated handling.A. Automated-Guided Vehicle Systems

    Performs similar kind of handling function as a

    mechanized tow tractor with a trailer.

    The essential difference is that an AGVS does notrequire an operator and is automatically routed and

    positioned at destination with intervention of the

    operator.

    Typical AGVS equipment relies on an optical

    or magnetic g idance s stem

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    164/383

    164

    or magnetic guidance system.

    In the optical application, tape is placed on thewarehouse floor, and the equipment is guide by

    a light beam that focuses on the guide path.

    A magnetic AGVS follows an energized wireinstalled in the floor.

    The primary advantage is the elimination of a

    driver and newer AGVS use video and

    information technology to follow paths without

    the need for fixed tracks.

    165

    Typically used in combination with conveyors.

    The products are selected in the warehouse, they aresorted as per specific specific shipment docks and

    taken onto the conveyors for moving out.

    Master cartons have a distinguishing code, these are

    read by optical scanning devices and automaticallyrouted to the desired locations.

    The rate of flow is customized to meet changing

    requirements.

    The benefits are

    (a) Reduction in labour, and

    (b) Increase in speed and accuracy.

    C. Robotics

    Humanlike machine that can be programmed

    by microprocessors to perform variousactivities.

    Robots are use in warehouses to break downand build unit loads to accommodate exact

    merchandise requirements of a customersorders.

    In break down process, the robot isprogrammed to recognize stocking pattern and

    place products in the desired position on aconveyor belt.

    Similarly, robots are used to build unit loads.

    Robots are used effectively in warehouses

    where prevailing environments make it

    167/383

    167

    where prevailing environments make it

    difficult for humans to work such as highnoise areas and extreme temperatures like cold

    storage freezers.

    The capability to incorporate artificialintelligence in addition to speed,

    dependability, and accuracy makes robotics an

    attractive alternative to traditional manual

    handling systems.

    Substitutes capital investment in equipment for labourrequired in mechanized handling systems.

    Though operates faster and more accurately, requires

    high degree of capital investment and complex to

    operate. Most automated systems are custom deigned and

    constructed for each application.

    Automated handling concentrates on order selection

    system at the master carton level as well as on highrise storage and retrieval system.

    A. OrderSelection System

    The handling of fast moving products in master

    169

    g g pcartons is fully automated from the point of

    merchandise receipt to placement in over-the-roadtrailers.

    Such systems use an integrated network of powerand gravity conveyors linking the storage.

    System is controlled by computer coupled withinventory and order processing systems ofwarehouse.

    Upon arrival, merchandise is automatically routed to

    storage position and inventory records are updated. U pon order receipt, merchandise is unitized to

    vehicle size and schedules made for selection.

    At an appropriate time, all merchandise is selected in

    loading sequence and automatically transported by

    conveyor to th loading dock. The only manual handling of merchandise occurs

    while stacking into transport vehicle.

    B. Automatic Storage and Retrieval System (ASRS)

    High rise handling systems are fully automated fromreceiving to shipping.

    The components of this system are storage racks,

    storage and retrieval equipment and control systems.

    The high rise are the vertical storage racks up to the

    height of 120 feet.

    moving products in and out of storage.

    jFunctions of storage & retrieval equipment

    (1) To reach the desired position rapidly.

    (2) To deposit or retract a load of merchandise.

    (3) To ensure merchandise flowing from

    production is automatically stacked to create

    a unit load.(4) To transport the unit load to the high rise

    storage area by power conveyor.

    C. Information-directed Systems

    All material handling movements are directed

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    172/383

    172

    All material handling movements are directed

    and monitored by the command ofmicroprocessors.

    To begin with all required handlingmovements are fed into the computer for

    analysis and equipment assignment.

    Analysis of handling requirements andequipment assignment is done in such a waythat direct movements are emphasized anddeadhead movements are minimized.

    Work assignments are provided to individualforklifts by terminals located on the truck.

    Communication between the computer and thetruck uses radio frequency (RF) waves with

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    173/383

    173

    q y ( )antennae located on the forklifts and high upin the warehouse.

    Information-directed systems can increase productivity by tracking material handler

    performance and allowing compensation to bebased on activity level.

    A single handling equipment may be involvedin loading or unloading several vehicles,

    selecting many orders, and completing severalhandling assignments, thus increasing thecomplexity of work direction.

    Packaging

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    174/383

    174

    Packaging can be categorized into two types viz.(a) Consumer packaging, which has a marketing

    emphasis, and

    (b) Industrial packaging, which has more of logistics

    emphasis.A. Consumer Packaging (Marketing Emphasis)

    - Consumer packaging design focuses on customerconvenience, market appeal, retail shelf utilization,

    and product protection.- Large containers and odd sizes may increase the

    consumer visibility but make poor logisticalpackaging.

    For example, shipping products fullyassembled such as motorcycles results in

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    175/383

    175

    y

    substantial reduction in density. A low density package would mean higher

    transportation costs and greater warehousingrequirements.

    B. Industrial Packaging (Industrial emphasis)- Individual products or parts are normally

    grouped into cartons, bags, bins, or barrels forhandling efficiency.

    - These containers are used to group individual products and are referred to as mastercartons.

    When master cartons are grouped into largerunits for handling, the combination is

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    176/383

    176

    g,

    referred to as containerization orunitization. The master carton and the unitized load

    provide the basic handling unit in thelogistics channel.

    The weight, volume, and fragility of themaster carton in an overall product linedetermines transportation and materialhanding requirements.

    If the package is not designed for efficientlogistical processing, overall performance ofthe system would suffer.

    Standardization of master carton facilitates

    material handling and transportation.

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    177/383

    177

    g p

    Standardization of master carton is beneficial evenin context of retail backend operations.

    (a) For instance, in case of shoe store as the contents

    of each master carton are known, it is not

    necessary to search through many cartons for aparticular style or size of shoe.

    (b) Allows master cartons to be more efficiently

    stacked, resulting in to less backroom congestion.

    (c) Complete identification of master carton contentsfacilitates completion of retail inventory and

    merchandise reorder.

    Standardized cartons are selected to achieve

    maximum conformity in increasing the density in the

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    178/383

    178

    maximum conformity in increasing the density in the

    trailer thereby eliminating dead space in stacking. The end result of standardized master carton usage is

    substantial reduction in total cost combined with an

    effective material handling system at both

    warehouse and the retail store. In situations, when master cartons of more than one

    size are required, extreme care should be taken to

    arrive at an assortment of compatible units.

    These different sizes of master cartons should resultinto modular compatibility.

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    179/383

    Another critical issue to be considered in package

    design is to determine the degree of protection

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    180/383

    180

    required to cope with the anticipated physical and

    climatic environments.

    The package design and material should combine to

    achieve the desired level of protection without

    incurring the expense of overprotection.

    In most cases the cost of absolute protection will be

    prohibitive and therefore the package construction

    should be a proper blend of design and material.

    Three broad functions of packaging are- Damage protection, Utility/ efficiency, and

    Communication.

    A.Damage Protection

    A major function of the master carton is to protect

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    181/383

    181

    products from damage while moving and being

    stored in the logistical system.

    Master carton also serve as a deterrent to pilferage.

    Achieving desired degree of protection involves

    tailoring the package to the product and selectingproper material for package construction.

    The determining factors are the value and fragility of

    the product; higher the value, the greater is the

    justification for nearly absolute protection. If the product is fragile and has high value, then the

    cost of absolute protection can be significant.

    183/383

    183

    in which it moves and is stored. Product fragility can be measured by

    product/package testing by means of shockand vibration equipment.

    If packaging requirements and cost areprohibitive, alternative product designs can beevaluated utilizing the same testingequipment.

    The end result is the determination of theexact packaging required to protect the

    product.

    During the logistical process, common causesof product damage are vibrations,i d i

    184/383

    184

    impact,puncture, and compression.

    Stacking failure can also result in damagewhile the product is in storage.

    The potential physical damage of poor

    stacking ranges from surface scuffing andmarring to complete product crushing,

    buckling and cracking.

    Typical methods of securing the packages are

    strapping, tie-downs, and use of variousdunnage materials that limit vibrations andshock.

    jBenefits ofUnit Loads

    - Unloading time and congestion at destination

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    187/383

    187

    Unloading time and congestion at destination

    is minimized.

    - Products shipped in unit load quantities

    facilitate material handling and inventory can

    be positioned rapidly for order selection.- Damage in transit can be reduced by unit load

    shipping and specialized transportation

    equipment.

    - All above factors lead to reduction in logistical

    cost.

    - A unit load can increase damage potential if it

    is not properly restrained during handling or

    transport.- Standard method of imparting stability to unit

    load include rope ties, steel strapping,

    adhesives, wrapping- both shrink wrap as well

    as stretch wrap.

    C. Communication

    Critical to content identification, tracking, and

    handling as the these are becoming necessaryto total channel success.

    (a) Content Identification

    - A very obvious communication role is identifyingk t t f ll h l b

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    189/383

    189

    package contents for all channel members.

    - The typical information includes manufacturer,product, type of container i.e. can or bottle, countand product code number.

    - The carton information is used to identify product

    for receiving, order selection, and shipmentverification.

    - Visibility is the major consideration, and materialhandlers should be able to see the label from

    reasonable distances in all directions.- High value products often have small labels to

    minimize the temptation of theft.

    (b) Tracking

    - A well controlled material handling system

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    190/383

    190

    A well controlled material handling system

    tracks product as it is received, stored,retrieved, and shipped.

    - A good control on movement reduces product

    loss and pilferage and is useful for monitoringemployee productivity.

    - Low cost scanning equipment, and

    codification increases the tracking capabilities

    and effectiveness.

    (c) Handling Instructions

    - Final role of logistics package is to provide

  • 8/9/2019 logistics-note-1-1230494545269880-2 (1)

    191/383

    191

    Final role of logistics package is to provide

    handling and damage instructions.

    - The information should be provided about any

    special product handling considerations such

    as glass containers, temperature restrictions,stacking considerations, or potential

    environments concerns.

    - If the product is dangerous, such as an

    explosive chemical , the packaging shouldprovide instructions for ealing with spills and

    container damage.

    represent integral parts of the logistical operatingsystem; as all three areas influence each other.

    For instance, automated handling cannot beefficiently designed without a high degree of mastercarton standardization, which in turn provide the

    opportunity to containerize individual products. The integration between material handling capability,

    transportation, warehousing, inventory policy andpackaging communication into customers logistical

    system leads to minimum handling during theexchange of merchandise.

    This type of integration is commonly found inphysical distribution.

    materials.

    The process scrap is unavoidable extra material

    removed from the stock of material while

    generating a component.

    For example, while making a machined componentsome material has to be removed in the form of

    chips.

    Quite often, while manufacturing any component

    some dimensions are not maintained and the lot isscrapped as these cannot be used in the assembly of

    the product.

    B. Surplus

    When the project or product needs a specific quantity

    of the item extra leftover cannot be used and this

    of the item, extra leftover cannot be used and this

    quantity is called surplus.

    The surplus quantity has to be disposed off.

    C. Obsolete

    When the item cannot be used in the product/ projectdue to changes that might have taken place in respect

    of dimensions, shape, colour etc, these are called

    obsolete items.
