A cost and capacity sensitive MRP processor for an assembly environment with high demand variability.

摘要

Most MRP systems are designed for manufacturing applications where assembly operations seldom dominate the process. Therefore, the optimum MRP procedures for a pure assembly environment may differ from the manufacturing-oriented MRP procedures. The purpose of this study is to develop an MRP processor for an assembly environment.; Important cost and capacity considerations must be included in the MRP process. The recent thrust of the research in MRP is at developing cost and capacity sensitive integrated procedures for master production scheduling and bill of material processing functions. The performance of nine such integrated procedures is tested in a multi-product, multi-level assembly environment characterized by a high degree of commonality index and a high variability in end item demand. A factorial design of experiment is used for simulation. The results of the experiment are analyzed by using analysis of variance (ANOVA) procedure.
