A simulation based approach for dock allocation in a food distribution center

This research endeavor focused on the warehouse receiv-ing process at a large food distribution center, which com-prises of trucks with goods reaching the destination ware-house, unloading and finally putting away the contents to the specific aisles. Discrete event simulation was used to model the current system’s functioning and to identify operational inefficiencies which were quantified through a detailed value stream mapping exercise. Inspired by ‘lean ’ philosophy, a dock allocation algorithm was de-signed to take into account the relationship between the dock location and the destination aisle to ‘optimally ’ as-sign the trucks to the docks. After validating the baseline, new scenarios incorporating the allocation algorithm were tested. Two of the scenarios showed an average reduction of 30 % in daily travel distance for the ‘put-away ’ person-nel. The simulation model also helped visualize the bene-fits that would accrue through the use of lean principles to reduce the non-value added time in warehouse operations. 1
