生活圈道路系統建設計畫補助評選模式之研究

Abstract

道路建設為促進生活圈發展的重要基礎建設，過去對於補助道路建設，是以各生活圈之財政能力為主要考量，並未考慮到各生活圈之間的差異，因而造成區域發展的不均。因此，本研究嘗試建立一有別於過去之補助程序，並藉此構建一公平、合理的補助評選模式。 本研究之補助評選模式分成兩部分，包括補助款分配與計畫評選。在補助款分配部分，利用灰關聯分析法，從十二項初擬指標中選取出七項補助分配指標，在指標權重部分，則使用結合熵權重與AHP權重之折衷權重法。在經由實例運算後，發現過去補助不公平之現象已獲得改善。 在計畫評選部分，本研究研擬三大標的與九項評估準則作為評選計畫的評估架構。此外，也將實務上常用之簡單加權法與模糊積分法做一比較。理論上，以考量各準則間相關性的模糊積分來評選道路計畫應較為適當，但此個案經由運算分析後，發現兩種方法的排序結果差異不大，顯示所選取的評估準則近似獨立。

Road system is an important infrastructure in the development of living perimeter. In the past, the government funded road projects based on the financial capability. It didn’t consider the difference among living perimeters so that area developments were unbalanced. This study tries to find a new funding procedure and develops a fair funding-evaluation model. The funding-evaluation model includes fund allocation and project selection. For fund allocation, this research applies gray relation analysis to select seven representative indicators from twelve initial indicators and uses Compromise Weighting method which combines AHP with entropy to show their importance. The results of case study indicate that an unfair phenomenon in the past has been improved. For project selection, this research establishes evaluation framework which includes three objectives and nine evaluation criteria to select road projects. Furthermore, we compare SAW method in practice with Fuzzy Integral method which is free of additive and independent assumptions. Theoretically, Fuzzy Integral method will be more appropriate. However, It is found from the case study that the results of two methods is similar. It shows that there exits less interactions among nine evaluation criteria.
