地下储气库方案的模糊综合优选

Study on the Fuzzy Comprehensive Optimization of Design Scenario for Underground Gas Storage

地下储气库的设计方案涉及因素较多,不能仅仅依据某个因素的优劣来决定哪种方案最好,而必须对方案从整体上进行综合评价。以某地下储气库方案为例,采用模糊层次分析法确定各因素的权重,然后建立岭型隶属度函数对各方案进行综合评价,结果所选方案与实际所选方案一致,说明该方法能够用于方案的优选。

The design scenario of underground gas storage involves in many factors,no any best design scenario can be taken as only based on some 'good' or 'bad' factors. Therefore,for the design scenario,a comprehensive evaluation has to be carried out integrally. This paper, take the design scenario of some underground gas storage as an example, determines the factors' weights with the fuzzy analysis of hierarchal process and establishes the mountain subjection degree functions to evaluate comprehensively the different scenarios. The calculation results show that the design scenario determined is in line with the actual scenario,that is to say,this method is available to optimize the the design scenario of some underground gas storage.
