The set of decisions that were previously addressed by the DSS(i.e., the layout design, allocation and assignment) provides a specific configuration for a warehouse scenario. Multiple iterations of the DSS allow for generating multiple warehouse scenarios,which differ in their layout configuration, storage allocation, and/or storage assignment criteria. In conclusion, a what-if multi-scenario simulation of operative performances (i.e., travelling for put-away, replenishment and picking) enables the decision-maker to assess the best solution for the warehouse design and management by the minimisation of the total travelling distance,
time and cost.
