Discussion on the Application of Value Engineering based on entropy technology in Optimal Selection for the Design Scheme of Highway Projects

Function evaluation methods usually include function cost method and function index method.Function index method is mainly used to reflect the function degree through evaluating the importance of every fuction.then calculates the value index with the relative cost index to evaluate the scheme.Using entropy technology and prior relation method in the value engineering,compared with conventional methods,the calculation results are more prevalent.Then,the theory was applied in design scheme of road route selection.Through engineering example,the theory was proved to be more effective.
