Research on Safety Evaluation Method for Hilly Area Pipelines Based on Entropy Weight-Fuzzy Hierarchy Analysis Method
In order to scientifically and rationally evaluate the safety of hilly areas'pipelines and establish their safety evaluation index system,a EW-FAHP-based safety evaluation model for hilly areas'pipelines was proposed.In which,basing on the traditional fuzzy hierarchical analysis method(FAHP),both entropy weight method(EW)and game theory was employed to improve it.In order to verify this model's scien-tificity and rationality,a hilly area pipeline was taken as an example in evaluating and comparing the FAHP method's safety analysis results.The results show that,the method established can reduce the eval-uation errors caused by subjective factors while retaining the data information to the maximum extent,and the evaluation results complies with actual situation of this pipeline.
