以AHP模式作為評估設計案的決策方法

Analytic Hierarchical Process for Design Alternative Selection

在當今的製造業環境中，顧客的需求日趨複雜，有時工程師必須同時設計很多的產品案例（Design alternative） 以因應這種需求不斷變革的時代；在遴選設計案時，設計者所考慮的評估準則通常很多，比如說產品的成熟皮、顧客滿意度、產品交期、或者是成本方面的問題，這些評估準則通常交錯複雜，很難有一個設計案例可以滿足所有的評估準則，本文擬將焦點擺在這個議題上，將評估準則的因素區分為定性與定量兩個部份， 而在作決策時，採用多目標的決策方法AHP（Analytic Hierarchical Process）模式，並 且以AHP方法的衍生軟體Expert Choice來實際操作範例，研究結果顯示，以AHP模式作 為評估設計案的決策方法應該是可行的。

In the currently manufacturing environment, The requirements of the customer have became n10re and more con1plex. Sometimes, engineerings must development many cases of the product design to cope with the needs of the customer. Basically, engineers make decision to select the product case according many criteria. This criteria include cost, customer satisfaction, due day... etc. The purpose of this paper focus this issue, and we try to present a decision model for the choice of the product design case. Firstly, the authors tried to divide criteria into two group: qualitative and quantitative. Secondly, we use the AHP method, one method of the multicriteria decision techniques, to make decisionin many design case. Finally, an illustrated expmple was used to demonstrate the feasibility of the AHP model.
