The Application of Trapezoidal Fuzzy AHP on Evaluation Item Weight Calculation of Highway Network Programming Schemes

IntroductionAttributes of highway network always lack ofpertinency and comparability. This characteristicintroduces the obstacles for respondent in projectassessment. In order to overcome the issue, we invitetrapezoidal fuzzy theory in obtaining criteria weights andAnalytic Hierarchy Process ( AHP) in ranking. AnalyticHierarchy Process (AHP) was proposed by Saaty, T.L. in19771], and has been widelyused in decision making, sinceit incorporates …

The Application of Trapezoidal Fuzzy AHP on Evaluation Item Weight Calculation of Highway Network Programming Schemes

The fuzzy theory is invited in this paper to calculate weights of evaluation items, which is a very important stage in highway network evaluation. Highway network evaluation is a composite of various attributes that lack of pertinency and comparability, and their commonality is that they are more or less tainted with uncertainty, with different daily decision making problems of diverse intensity, the results can be misleading if the fuzziness of human decision-making is not taken into account. So we introduce fuzzy theory into the measurement of evaluating weights to overcome the issue and Analytic Hierarchy Process in scheme ranking. It is testified to be a more reliable way through the case study of Yangtze River Delta highway network evaluation.
