GIS-based Fuzzy Comprehensive Evaluation on Underground Gas Pipeline Risk
The evaluation of tbe risk of underground gas pipeline can provide effective decision support aid. It is crucial to tbe establishment of a comprehensive safety evaluation and management system for the urban underground gas pipeline. This paper presents a method of GIS-based fuzzy comprehensive evaluation on underground gas pipeline risk and elaborates the flow of fuzzy risk evaluation in detail. Meanwhile, a fuzzy comprehensive evaluation model is built herein by analyzing the pipeline risk factor weight by means of analytic hierarchy process according to the fuzzy evaluation matrix for relative single-factor membership. Finally, a fuzzy comprehensive evaluation with test data is made on the failure to research the regional gas pipeline issue, the relative risk value of the pipelines in the area is calculated and visualization is made in 3DGIS scene.
