Simulation of Packing Area Throughputs under DWASP (DLA Standard Warehousing and Shipping Automated System)

摘要

This report details the results of a simulation of the Defense Logistics Agency Standard Warehousing and Shipping Automated System (DWASP) Increment II for Defense Depot Ogden, Utah (DDOU). The system under study includes the printing of the Issue/Release Receipt Document (IRRD), packing, and offering to transportation for bin operations. In addition to these functions, all associated hardware such as conveyors, automatic sealers, bar code readers, and printers are modeled as well. The analysis indicates that there were two major areas for concern--the multiline packing and the single line offer stations. In the packing area, there was an imbalance in the work among the packers. Specific recommendations in packing include alteration of the current scheme for assigning work to multiline packers and placing a cap on the maximum size shipping unit. In the offer area the original configuration could not accomplish the required throughput. The addition of another diversion belt and splitting up to offer function into three components performed in different areas resolved the problem. (fr)
