Abstract: Management and running of technological processes of
production, warehousing, packing, shipment of finished products to
buyers, etc. often is not possible without appropriate
transportation system in multi floors production facilities.
Therefore all design processes, construction and dimensioning, of
transportation systemsneed to be rationalize, speed up, and make
them as simplest as possible. In this paper is presented developed
utilize
software "SI ! " as a tool for rationalization of constructional
and working parameters calculation duringdevelopment of new one or
changing of parameters on e#isting pending conveyors.
Key words: internal transport, pending conveyer, modelling,
simulation

Modern development and technologicalimprovements had a great
impact on structure,management and philosophy of production
systemsregardless to industrial field which they belong. It
isimportant to note that, by opening of local markets inlast few
decades, is made such ambient that existenceof production systems
in any moment is veryquestionable, in other words on global market
only the best survives. This situation doesnt need to be consideras
a threat, contrary this situation can be consider as aopportunity.
amely, only production systems whoseexistence is based on
innovation, efficiency andeconomical sustainability will be able to
advance andenlarge its share on global market. Main goal of each
production system is achievement of planned production
!quantitative, qualitative and on time". #ll processes in
production systems, except directmanufacturing, are costs making
processes!transportation, quality control, warehousing, preventive
maintenance, etc.", there is no creation ofadditional values to
products. $owever, those costmaking processes are necessary in
production processes, and because of that it is important to find
themethods to decrease%minimise share of those processesin whole
production cycles. Modern productionsystems required that this
decreasing%minimising ofcost making processes share in production
cycle needto be implement during whole production system life,from
a moment of business idea creation until amoment of closing of
business sub&ect. Implementationof this approach significantly
increases concurrentabilities of business sub&ect and its
belonging production processes.
