本研究旨在應用多準則決策模式（MCDM）進行運輸政策決策過程之評估，進而檢驗運輸政策各種準則之間的相依關係。以決策實驗室分析法（DEMATEL）建立影響關係圖（IRM）與網路關係圖（NRM），探討影響運輸政策決策之因果關係。再以分析網路程序法（ANP）取得準則之權重，接著以最佳化妥協解方法（VIKOR）找出最佳運輸模式。以花蓮對外交通為例，實證結果顯示此模式可有效處理複雜問題，辨識其因果關係，評估準則之優先順序，進而挑選出最佳妥協解。

The purpose of this study is to propose a transport policy decision-making process using a MCDM (multiple criteria decision-making) model to examine the dependent relationships among variable criteria of transport policies. DEMATEL (decision-making trial and evaluation laboratory) is employed to construct the IRM (impact relation map) and NRM (network relation map), which illustrate the influential network of the transport policy decision-making model. ANP (analytic network process) is adopted to evaluate the weights of criteria. VIKOR is then used to select the best transport mode. The case of Hualien is demonstrated and the empirical results reveal the proposed model is powerful and effective to identify the influential network, priority of criteria, and select the best compromise solution to a complicated problem.
