隨著組織內使用各種軟體系統的成長，如何選擇最適當的軟體來滿足組織的需求， 已經成為一個很重要的決策問题。軟體選擇的方法論應該要能夠同時評估有形及無形 的準則及其相對的重要性，分析層級程序法是一種廣為應用在多評準決策問题的決策 方法，軟體選擇決策利用階層化的結構來選擇及評估特定應用領域的套裝軟體。此論 文探討分析層級程序法應用在不同軟體選擇決策的可行性，同時也討論選擇不同種類 軟體系統的準則。

The increasing variety of software systems deployed within organizations, has made selecting appropriate software to optimally fit their requirements a significant decision. The software selection approach should be able to evaluate the relative importance of both tangible and intangible criteria. The Analytic Hierarchy Process (AHP) is a popular methodology for multi-criteria decision making problems. The software selection decision process has led to the hierarchical structure being applied at each specific application area in evaluating and selecting software packages. This study investigates the feasibility of applying the AHP in various software selection decisions, and also reviews and discusses the criteria used for selecting software systems.
