MRP與DDMRP管理機制之比較分析

Abstract

在現今全球競爭激烈的環境下，物料管理為企業所應重視的課題之一，在實務上，許多公司利用MRP系統為主要的物料管理機制，雖然MRP系統被廣泛使用，但該系統本身物料相依性的特色容易讓物料管理常處於十分緊張的狀態，業界員工需時常關注MRP系統以防有缺貨的狀況，因此即使業界內部有MRP系統，在實務上員工基於對MRP系統的不信任，反而偏向使用其他軟體來管理物料。針對MRP在使用上的困難以及不足之處，Carol Park與Chad Smith發展出DDMRP系統來補足MRP系統。因此，本研究透過文獻整理來探討MRP與DDMRP兩種管理機制之間的差異，再利用Excel VBA軟體來模擬兩者的物料管理邏輯，並分析模擬後的結果，期望藉由模擬後的結果，提供給現在仍然使用MRP系統的業者，使其認識DDMRP系統並激發想法，幫助業界考慮採用DDMRP系統。

In today's highly competitive environment, materials management is pretty important to enterprises. In practice, many companies apply MRP system to manage their materials. However, interdependence of materials in the MRP makes the system nervous. As a result, employees have to pay attention to the system all the time in order to avoid lack of supplies. In addition, although many companies apply MRP system, employees prefer to use other soft wares to manage materials because employees do not trust the MRP system. Therefore, Carol Park and Chad Smith developed DDMRP system to complement MRP system. Consequently, This research compares differences between MRP and DDMRP and models logic of MRP and DDMRP in order to make companies who uses MRP system be familiar with DDMRP and consider using DDMRP as their materials management system.
