Uncertain Type of AHP Method in Layout of Expressway Service Areas

In view of the defects of the traditional analytic hierarchy process (AHP), the uncertain type of AHP and the improving optimal transitive matrix were first applied to the layout of service areas, and the basic principles and steps of arithmetic of this method were introduced. Then, the layout optimal model of Daguan Service Areas was built in Chongqing, the weights of assessment indices were fixed and the optimal results were obtained. The results indicate that, this method can fully consider the major factors of layout service areas; besides, it can reflect the uncertainty and fuzziness of layout service areas better than traditional AHP. The higher reliability and accuracy of index weight can be achieved by using the optimal transitive matrix method to calculate interval number judgment matrix. Thus, the comprehensive results are proved to be credible and practical by uncertain type of AHP in layout of service areas, and it is propitious to enhance the rationality and science of layout service areas.
