Abstract:
This thesis presents a Simulation for Predictive Control (SimPC) as a decision making tool for improving the operation of non-automated distribution centers (DCs). SimPC is focused on determining the viability of a given truck–dock assignment schedule, including arrival times and dock assignments for inbound and outbound trucks at a large DC. SimPC also serves as an evaluation tool to perform analysis of iterative control procedures of system parameter adjustments while searching for a viable operational schedule. SimPC can utilize real-time data from DC’s warehouse management system (WMS) to obtain the current state of the DC, which serves as the initial conditions for the simulation. SimPC emulates the decision rules imbedded in SAP WMS, which includes assigning tasks to system-guided resources, selecting storage locations for inbound operations and determining retrieval locations for outbound operations. The SimPC model provides insight for identifying critical scheduling components along with guidance for operational and tactical solutions. It also serves as a tool to verify these solutions.
