THE METHODOLOGY FOR SUBSTANTIATING THE MATERIALS HANDLING EQUIPMENT OF A UNIT LOAD WAREHOUSING SYSTEM

The most important objectives of a warehouse system organization design's to substantiate the structure of the materials handling equipment fleet, which directly determines the quality of functioning of the warehouse system in the supply network of industrial enterprises. The complexity of the above objective's preconditioned not only by the existing variety of handling equipment models, but also by a large number of factors affecting the efficiency of the equipment fleet, being determined by the specifics of cargo flows and the space-planning solution of a warehouse. This paper studies the problem of substantiating the optimal number of materials handling equipment units in the composition of various technological groups in a unit load warehouse system. Methodology implies iterative optimization of the equipment quantity according to a criterion of minimization of total aggregate costs caused by equipment maintenance or downtime of transport vehicles with various values of the number of service channels for transport vehicles.
