基于熵权法和AHM法的地下储气库设计方案优选研究

Optimum Program for Underground Gas Storage Projects Based on Entropy-weight AHM

以某城市拟建造天然气地下储气库为例,选取垫层气量、注气结束时的最大地层压力、注采井数、压气站功率、工程投资、使用寿命6个参数作为主要评价指标,采用属性层次分析法(AHM)和熵权法确定各指标的综合权重,对不同设计方案进行了综合评价,优选出最佳设计方案,并将设计方案的总排序结果与灰色关联分析法、AHP-MCZ法进行比较。结果表明,该数学模型简单,计算量少,不需要进行一致性检验及对矩阵进行调整判断,对多因素、多层次的复杂问题评判效果较好,评价结果既体现科学性、又不失主观性。

Taking underground natural gas storage inacing as an examplei AHM method is used to evaluate design projects of underground gas storages comprehensively.And six parameters such as the general annual cost,the cushion gas volume,the maximum formation pressure,the number of injection and recovery wells,the power and life of compressor stations are taken as main indexes to be considered.The comprehensive weighting of six indexes are calculated basd on the method of AHM and entropy-weighting.And the comprehensive ev aluation of each project is conducted.The results indicate that attribute A HM method matches AHP method well.The calculation result of the example indicates that the AHM is a simple mathematic model,with is easy operation.Especially it can get a good assessment result for multi-factor and multi-hierarchy complicated problems.The result of evaluation embodies the science without losing the subjectivity.
