Rough Set Comprehensive Evaluation Model for Environmental Security Effect of Highway Construction Projects

On the basis of considering each factor of environmental effect of highway construction projects, a new evaluation method for environmental security effect of highway construction projects is set up. Based on the grades of evaluation´s definition, the extension rough set evaluation method is utilized to assess environmental security effect of highway construction projects. Analyzing the elements that influence environmental security effect of highway construction projects, we build up a rough set comprehensive evaluation model to assess environmental security effect of highway construction projects. The multi-ingredient environmental security effect of highway construction projects assessment is transformed into the single-object decision, and the results can directly show the integrative level of environmental security effect of highway construction projects. It was applied to the practical evaluation and some positive results were obtained. Applied results indicate that the method is feasible.
