Research On Evaluation Of Goal Sustainability Of Freeway And Bridge-Project

Project post-evaluation is indispensable information feedback and control tache in the project management cycle. In the project post-evaluation, experiences and lessons in the project management cycle can be summarized, and then more project management level can be improved and perfected. Goal sustainability evaluation of project is one of main contents of the project post-evaluation. The evaluation of freeway and bridge construction project goal sustainability is made after the completion and a period of operation of the project,through analyzing and evaluating for condition of exteriority (development of social and economy,management of system,policy and code,condition of road net,condition of transportation,construction of corresponding establishment)and interiority (system of function,interior management,circumstances of service,charge for highway,the condition of operation,the quality of project),to judge the project of freeway operate smoothly or not,and the project have the ability to achieve persistently the target of project or not.Compared evaluation with abroad, the national project's goal sustainability evaluation which is weak in the foundation, starts late. The methods with much faultiness don't adapt the stage of need of project's evaluation. The main problem at present is the lack of a set of unified and perfect evaluation index system, scientific effective quantitative methods and the corresponding criterion.In this background, the paper sets up the comprehensive evaluation index system of the evaluation of freeway and bridge construction project's goal sustainability on the basis of studying and collecting data, and gives the weightiness of the indexes with analytical hierarchy process (AHP) and expert consultation, using the fuzzy evaluation theory order to evaluation comprehensively freeway and bridge construction project's goal sustainability. Finally, the paper validates the index system and the evaluation method with the case of Lianxu freeway and the result shows that the model has fine practical value and foreground.
