Abstract : In this paper, we conduct a simulation study to evaluate the impact of using imperfect advance demand information ADI in a single stage production-inventory system. We mean by ADI the fact that the production system receives customer orders in advance of their due-dates. We consider four types of ADI: 1 Perfect ADI, 2 ADI with imperfect due-dates, 3 ADI with imperfect demand quantities and 4 ADI with updates. The production system is controlled by a modified base-stock policy which has two parameters that are S, the base-stock level, and L, the production release lead time. We intend to shed light on the impact of imperfect ADI ADI types 2, 3, 4 on the performance of production-inventory systems. The aim of the simulation study is twofold. Firstly, the objective is to find the optimal parameters of the modified base-stock policy and secondly, to evaluate the benefits of imperfect ADI in a production-inventory system.

Keywords : supply chain inventory management Imperfect advance demand information single stage production-inventory system modified base-stock policy.
