| Summary: | 碩士 === 國立交通大學 === 交通運輸研究所 === 91 === The process of ranking the priority of constructing the highway, including Provincial highway and County highway is conducted as follows. First, DGH (Directorate General of Highway) is following the principle of “Highway Construction Planning in Taiwan” to make relative plans that should match up the national policy. Second, those plans are verified by MOTC (Ministry Of Transportation and Communications) and are appraised and decided by EY (Executive Yuan). Third, DGH checks the annual budget of all plans and sets up its priority then transfer those plans to MOTC and EY to evaluate and get the permission. Finally, those plans is executed after the budget is approved by LY(Legislate Yuan) .
Over process, no matter in making or appraising plans by any layer of government, no systematic assess method is applied, although the decision usually made through several times of meeting and discussion. For the best utilization of country resources, this study begins with reviewing the method of AHP、SAW、ELECTRE、TOPSIS、MCDM、Delphi and Cluster analysis etc., as well as relative cases of internal and overseas. And then analyze the present situation and future develop characters regarding property、economic、environment and traffic in I-Lan County, according to “Integrate Development Plan in I-Lan County ”. Then set up the structure of goal、object and criteria to assess the priority ranking of highway construction on Provincial highway and County highway in I-Lan County from the year 2004 to 2008. AHP and Delphi method is used in this study to weight criteria, and SAW is applied to calculate the total score of each construction case, and to determine the rank of priority. Finally, the author uses CA(cluster analysis) to cluster all cases and list annual budget in I-Lan County from the year 2004 to 2008, for the purpose to serve as a reference for government in making decisions.
