基于熵权系数的地下储气方案优选

Entropy Coefficient-based Optimization on Design Cases of Underground Gas Storage

将熵概念引入天然气地下储气库方案优选,提出了一种结合备选方案固有信息和决策者主观判断力的实用权值系数方法,即用改进层次分析法求取主观权系数,用信息熵求取客观权系数,最后将主客观系数相结合得到一个最佳权系数,从而使得优选的方案更加符合实际。应用该模型对备选的6座天然气地下储气库的建库方案进行了优选,最终优选结果和其它方法及实际优选结果一致,表明了该模型的实用性和有效性。

By introducing entropy into the optimization of underground gas storage selection, a method of real weight coefficient combining inherent information of alternative projects with decision maker's subjective sense is presented. In this method,subjective weight of factors in project is determined through improved hierarchic analysis process while the external weights through information entropy, then the two are combined to gain the best weight factor to correspond with actual situations. This model is applied to 6 alternative underground gas storage design cases and it's proved to be practical and effective agreeing with both results using other methods and actual selection.
