利用資產配置方法於庫存不確定性之研究

Abstract

供應鏈不易管理的最主要因素就是不確定因素的存在，不確定因素直接或間接影響企業的績效，如：成本、品質、彈性、決策… 等，造成企業有形或無形的損失，因此企業在營運的過程中會面臨哪些不確定因素及如何因應為一重要課題。而面對現今多變的市場環境與需求不穩定之狀況下，供應鏈變動頻繁且不易掌握，於是同步化的機制將會是未來供應鏈管理所必行的一個方法。 所以針對不確定因素及傳統供應鏈的問題，本研究引用「同步供應鏈管理架構」之概念，試圖利用同步供應鏈管理流程，以建立一同步化之模擬環境，並選定部分方法學展示同步化的流程。而本研究目的便在於同步化流程的展示，以提供供應鏈管理領域更清楚了解同步化的重點所在。同時利用資產配置的方法學，應用於同步化供應鏈流程，同步整合需求和庫存之間的風險管控，同步調整庫存水準，以展現資產配置在協同各構面風險之能力。 最後將建構之同步供應鏈模擬環境進行模擬運作，以證實同步供應鏈管理流程和資產配置控制風險之主要績效。

Difficulties occur when managing a supply chain because there is lots of uncertainty in the market. With those uncertain factors, the performance of supply chain management may not always be efficient and effective, resulting the industry suffered enormous damage. Consequently to reduce the influence of uncertainty in supply chain processes should be one of the most vital topics for businesses to enhance their performance. Methodologies for concurrent engineering may be the answer to those difficulties occurred in the future. To answer these problems in the field of SCM, the thesis adopts the Synchronous Supply Chain Management Architecture (SSCMA) to build a concurrent simulation process. And concurrent processes are also been deployed to demonstrate the usage and usefulness of SSCMA. Moreover, for the purpose of meeting the balance between demand and inventory, the asset allocation method with SSCMA for concurrent risk control is integrated and implemented in the thesis. As a result, the capability of collaborating multi-phase risk with the concurrent adjust inventory level is presented as well. Experiments through some simulation are conducted by the implementation of the SSCMA model. The effectiveness of SSCMA and advantages of asset allocation method is proved to be significant as the result of the experiments.
