TOPIC

Comparing Supply Chain Replenishment Policies Using Optimum-Seeking Simulation

Abstract:

The choice of replenishment policy in supply chains is a challenging and important problem. The available studies have still some contradictions and problems of comparing these policies. The important problems addressed are setting of decision variables and multiple performance measures. The work reported in this presentation is part of a larger study aiming to perform a rigorous and objective comparison of supply chain replenishment policies. A hypothetical single-stage supply chain system, facing time-varying demand, is modelled, and experiments are conducted using discrete-event simulation to predict how each replenishment policy performs. The optimum-seeking simulation methodology is used to determine “optimal” control parameter settings for each policy, and the performance of the system under each policy (with optimal parameter settings) is compared. The two primary performance measures of interest are average total inventory and customer service level. The control parameters whose values are being determined are: lot size and reorder point (for the reorder point system); and Kanban size and the number of containers (for the Kanban system). In each set of optimum-seeking simulation trials, the objective is to minimize the average total inventory subject to a specified lower limit on the customer service level.
