The Study Of Fuzzy Evaluation Method In The Society Assessment Of Highway Construction Project

Whether in the past or now, the evaluation of investment projects in China is mainly focused on economic evaluation and technology evaluation. Most of the social assessment is based on the social benefits analysis. The form of the social benefits under technical and economic analysis occupied the absolute dominant position, which the social evaluation reflected more like accessories to the economic evaluation. Social assessment is an important and necessary part in the feasibility study stage and post-evaluation stage.To define the scope of social evaluation and study the evaluation method is widely concerned in theoretical research and practice. Throughout the social assessment of development process in China, there have formed methods to guide the social evaluation of investment projects in various fields.Such as in water conservancy project, aviation industry, oil field development, railways and other fields. While in the Highway Engineering, there have no system to guide social assessment. From this perspective the article studies the social assessment which appropriate to the feasibility study stage.On the basis of extensive reading relevant materials literature at home and abroad, the article constructs a framework about Highway construction project, which combined with the characteristics of Highway construction projects. The paper details the framework which includes the principle of community, content, methods and steps for evaluation of highway construction projects. Meanwhile, the article collates and analyzes the key factors that obtain from the research. Then I construct the social assessment index system of highway construction projects. It elaborate the index system from the aspect that project's impact on social development, social environment, adaptation and social interaction, social risk (The scope of the system defined to service for the Preliminary assessment). Since the nature of social evaluation is multi-objective, I combine analytic hierarchy process and fuzzy comprehensive evaluation. Then I establish the multi-objective fuzzy comprehensive evaluation model. Describe the method and use participatory theory to actual cases then analysis.Finally, the paper summarized the problems founded in the instance and made the prospects then proposed suggest.
