IMPACT OF REQUIRED STORAGE SPACE ON DIFFERENT STORAGE POLICY IN A UNIT-LOAD FISHBONE WAREHOUSE

摘要

Different storage strategies and warehouse layout will produce different average picking distance which is generally used to estimate the picking cost of a warehouse. This paper will consider the three storage strategies of real space requirements including random, full turnover-based, and class-based storage policies to be applied to the fishbone warehouse. Analytical models were established and the performance of different warehousing strategies was derived through the gold search algorithm. It is found that the class-based warehousing strategy is the most reasonable storage policy. It balances required storage space and picking distance well. At the same time, we provide a suitable partition for different quantities of skus and different total demand warehouses, which can provide reasonable storage management experience for warehousing practitioners.
