基于组合赋权-灰色关联投影法的地下储气方案优选

Optimum Method for Underground Gas Storage Projects Based on Combination Weight-gray Relation Projection Method

针对天然气地下储气库方案优选存在指标要求多、难以选择等问题;运用熵权法和层次分析法(AHP)相结合确定各指标的组合权重系数,并利用灰色关联投影法的基本原理建立地下储气库方案优选模型。通过以某天然气地下储气库方案优选为例,对所建立的优选模型的适用性进行了验证。结果表明:该决策模型应用于地下储气库方案优选中是切实可行的,所得的结果与灰色关联分析法得到的结果基本一致;这为该领域的评估提供了一种科学合理的决策依据,对指导地下储气库的建设具有重要意义,因而具有较高的推广应用价值。

Aiming at the problems that the underground gas storage projects optimization needed more performance requirements, selected difficult and other issues, the combination of Analytical Hierarchy Process （AHP） and entropy method was used to determine the index was constructed according to gray relation weight coefficient, and the underground gas storage projects optimization mode projection method. Taking an underground gas storage projects optimization as an example, the applicability of constructed model in underground gas storage projects optimization was studied. The results showed that the optimization model was practicable to using in projects optimization, the obtained result of combination weight-gray relation projection method process and gray correlation analysis was basically consistent. A scientific and rational decision-making was provided to the assessment of underground gas storage field and it had an important significance in guiding the construction of underground gas storage, so it had high applied value.
