供應鏈管理的觀念在於整合採購、生產和運送產品及服務至顧客一連串的活動，但由於各個企業間存在差異，要協調與整合供應鏈上的所有成員是一項極為困難的工作，尤其全球化供應鏈橫跨地理疆界，管理更加困難。全球化供應鏈管理可為企業帶來許多的利益，然而全球化本身所造成的高度不確定性，使得我們懷疑是否採行全球化供應鏈的企業，其績效就能提升。本研究提出一績效評估模式，再藉由多重代理人模式模擬複雜的供應網體系，接著以模擬方法比較採行全球化策略與本地化策略的供應鏈績效產出，最後結果發現不同體系之供應網在全球化策略實行後，對供應鏈造成的影響也不同。 The ideal in supply chain management is the fully integration of business process from end consumers through original suppliers. And we know that it is very difficult to coordinate and to integrate all members of a supply chain, especially a global supply chain that the members are dispersed in a number of countries. It is obvious that we can get some benefits from the globalization. However, because of the higher uncertainty of the globalization itself, we also get some trouble and losses. So we have the reason to doubt that whether the globalization of a supply chain can really improve its performance of not. In this paper, we first proposed a multi-agent based simulation model for evaluating the performance of a supply chain to help us in decision-making. Secondly, we used simulation approach to do the performance comparison between the globalization and localization of a supply chain. And we also investigated the performance variations caused by the effects of the different types of supply chain network. We find out that globalization / localization and different network types may significantly influence the performance of a supply chain.
