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.

Cost advantage or Productivity advantage
-C
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.
8/9/2019 logistics-note-1-1230494545269880-2 (1)
17/383
17
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.
8/9/2019 logistics-note-1-1230494545269880-2 (1)
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.
8/9/2019 logistics-note-1-1230494545269880-2 (1)
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.
8/9/2019 logistics-note-1-1230494545269880-2 (1)
43/383
43
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.
8/9/2019 logistics-note-1-1230494545269880-2 (1)
44/383
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.

Concerned with managing work-in-process
inventory as it flows between the stages of
manufacturing.
Formulates a master production schedule thatsubsequently facilitates arranging for timely
availability of materials, component parts,
and work-in-process inventory.
Is not concerned with how production
occurs but rather what, when, where
products will be manufactured.

Difference between Physical distribution
and Manufacturing Support
Physical distribution attempts to serve the
desires of the customers and therefore must
accommodate the uncertainties of consumerand industrial demand.
Manufacturing support involves movement
requirements that are under the control ofmanufacturing enterprise.

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.

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.

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.

72
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

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

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.

Forecast Components
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-
down approach.

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.
Customer service levels and geographic
8/9/2019 logistics-note-1-1230494545269880-2 (1)
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.

A. Product Movement
8/9/2019 logistics-note-1-1230494545269880-2 (1)
117/383
117
- 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.

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

121/383
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.

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

- Transport cost per unit of weight decreases as loadvolume increases.
- Fixed costs of pick up and delivery as well asadministrative costs get spread over additionalvolumes.
- Smaller loads must be consolidated into larger loads.
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.
- Higher density products allow fixed costs to bed dditi l i ht lt th

- Attempts are made to increase product density so thatmore can be loaded in a vehicle to utilize its capacity.
D. Stow ability
- Refers to product dimensions and impact of the sameon vehicle utilization.
- Odd sizes and shapes as well as excessive weightsand lengths do not stow well and typically waste
space.- Though density and stow ability are similar, products
may have same density that stow differently.
- Items with regular shapes are easier to stow than oddh d it

144
shaped items.
- While the steel blocks and rods have the samedensity, rods are more difficult to stow because oftheir length and shape.
E. Handling
- S pecial handling equipments may be required forloading or unloading trucks, trains, or ships and theunitization/ palletization affects the handling cost.
F. Liability
- Product characteristics such as susceptibility to
damage, perishability, susceptibility to to theft,susceptibility to explosion affect the risks and henceclaims.
G. Market factors
8/9/2019 logistics-note-1-1230494545269880-2 (1)
145/383
145
(a) Back-haul i.e. vehicle returning back to the
point of origin with load.
(b) Dead head to be avoided because empty
returns incur labour, fuel, and maintenance
costs.(c) Thus design of logistics system must add
back-haul movement wherever possible.
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.
8/9/2019 logistics-note-1-1230494545269880-2 (1)
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.

Containerization
8/9/2019 logistics-note-1-1230494545269880-2 (1)
152/383

C
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.
Many firms that modify their material

153
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.
Piggyback services mostly move under contract.
Material Handling
8/9/2019 logistics-note-1-1230494545269880-2 (1)
155/383
155
g
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
8/9/2019 logistics-note-1-1230494545269880-2 (1)
158/383

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.
B. Walkie-Rider Pallet Trucks
Low cost effective method of material
8/9/2019 logistics-note-1-1230494545269880-2 (1)
161/383
161
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.
8/9/2019 logistics-note-1-1230494545269880-2 (1)
162/383
162
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.
Semi automated Handling
8/9/2019 logistics-note-1-1230494545269880-2 (1)
163/383
163
j Semi automated system supplements a mechanizedsystem by automating a specific handling
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.
B. Sortations
Typically used in combination with conveyors
8/9/2019 logistics-note-1-1230494545269880-2 (1)
165/383
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

166
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
8/9/2019 logistics-note-1-1230494545269880-2 (1)
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.

g
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.

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.

The susceptibility to damage of a givenpackage is directly related to the environment
8/9/2019 logistics-note-1-1230494545269880-2 (1)
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
8/9/2019 logistics-note-1-1230494545269880-2 (1)
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.

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

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

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

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.

194/383
194
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

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.
