新武器發展（new weapon development, NWD)是由數量及種類繁多的 活動所組成，因此是一個龐大且複雜的流程。當NWD流程中某個活動產生 問題，追蹤其上游影響活動及下游被影響活動，亦即「上下游關聯活動分析 (contextual analysis)」，對NWD流程的管理，變得格外重要。本研究已提出一 個三階段的系統化方法，以支援NWD流程中問題活動的上下游關聯活動分 析。首先，NWD流程定義階段利用設計鏈作業參考模型（design chain operations reference-model, DCOR)描述及界定NWD流程及活動的範圍。接 著，上下游關聯活動分析階段應用NWD活動與關鍵績效指標（key performance index, KPI)間的關聯性，過濾出NWD問題活動的上游影響活動 及下游被影響活動。最後，系統導入階段依所提上下游關聯活動分析方法，利 用Proteg6建置一資訊系統。

The new weapon development (NWD) consisting of multitudinous activities is a large and complicated process. The contextual analysis, i.e. tracing the influential upstream activities and affected downstream activities, for a problematic activity is important for NWD process management. This research has proposed a three-phased systematic approach for the contextual analysis of problematic NWD activities. First, the new weapon development process definition phase uses design chain operations reference-model (DCOR) to describe and determine the scope of NWD process and activities. Next, the contextual analysis phase applies the relativity of NWD activities to key performance index (KPI) to filter the influential upstream activities and affected downstream activities. Finally, the system implementation phase implements the proposed contextual analysis approach with Protege.
