AHP與修正后AHP以方案排序為基礎的比較
A Comparison Between Ahp and Modified Ahp Based on Rankings Among Alternatives
摘要
本文介紹一結合分析階層程序法(AHP)及多屬性效用理論(MAUT)之修正後的分析階層程序法(AHP’)。本文並說明AHP與MAUT之間尺度化的轉换。藉由專家學者問卷使用三種評估方式：直覺判斷、AHP、及AHF’，本文比較AHP與AHP’表現決策者偏好的效果。在問卷中控制使用AHP及AHP'的順序且使用該二法前後均採用直覺判斷的設計。該問卷比較係以第二高速公路沿線高架橋下土地使用方案評估為一逼真案例。即使大多數受訪者認為AHP较AHP’為佳，但分析結果發現在表現決策者偏好能力方面，AHP’較AHP為佳。此比較係以方案優劣排序為依據，而非以偏好结構為比較標準。

The paper introduces a modified version of Analytic Hierarchy Process (AHP), or AHP', as combination of AHP and multiattribute utility theory (MAUT). The transformation of scaling between AHP and MAUT is demonstrated in terms of matrix algebra. A comparison between the effectiveness of AHP and AHP' in expressing decision makers' preferences was made by sampling among planning practitioners applying AHP and AHP'. The order of applying AHP and AHP' was controlled and the holistic judgments were made in the beginning and the end of the questionnaire. A realistic planning problem of evaluating alternative land uses under an overpass of the Second Highway was designed for conducting the survey. AHP' performed better than AHP in terms of expressing decision makers' preferences though most respondents preferred AHP to AHP'. The comparison was based on decision makers' rankings among alternatives, rather than on preference structures.
