The Analysis of Selected Unit Load Storage Systems

Abstract : The focus of the research is the development of optimization procedures and techniques to aid warehouse planners in the design and evaluation of selected unit load storage systems. The basic assumptions of the research include a randomized storage policy; FIFO lot rotation; unit load storages and retrievals; no rewarehousing of stock; known lot sizes and known replenishment schedules. The study concentrates on block stacking to illustrate the methodology used and issues considered in the analysis of unit load storage systems. Other storage methods investigated include single-deep pallet racks, double-deep pallet racks, and deep lane systems. Analytical models are developed and solution procedures are derived for a number of storage problems not previously addressed in the literature. Previous research in this area tends to be fragmented; hence, the study provides a unified body of knowledge related to the storage of unit loads using block stacking as a storage method.
