This involves taking company data (e.g., several weeks of actuals orders, or today’s expected orders from a forecast) and then, in an instance of a WMS, the orders are “played out” as if they were live orders to see the results. WMS simulation can be used to test process adherence (e.g., retail compliance adherence), to test the impact of WMS configuration changes on cost or performance, or to understand resource requirements and the assignment of resources for a shift’s expected work. Only a few WMS solutions have a simulation capability.
