基于G1权重法和物元分析法LNG储备站后评价
|
摘要
从目标实现、实施过程、生产运行、经济效益、社会及环境影响、可持续性等方面构建了城市燃气LNG储备站工程项目后评价指标体系,并选取G1权重确定法和物元分析法构建LNG储备站工程项目后评价数学模型。按G1权重确定法确定评价指标序关系,对相邻评价指标之间的相对重要程度赋值,计算指标权重。确定经典域物元、节域物元和待评估物元,计算关联函数值和隶属度向量,确定评价等级。结合工程案例,对4个LNG储备站工程项目进行后评价。
The project post-evaluation index system of LNG reserve station of city gas is constructed from the aspects of goal realization,implementation process,production operation,economic benefit,social and environmental impact,sustainability and so on. G1 weighting determination method and matter-element analysis method are selected to construct a project post-evaluation mathematical model for LNG reserve station of city gas. The order relationship of evaluation index is determined according to G1 weighting determination method,the relative importance degree between adjacent evaluation indexes is assigned,and the index weights are calculated. The classical domain matter-element,the node domain matter-element and matter-element to be evaluated are determined. The correlation function value and membership vector are calculated,and the evaluation level is determined. The project post-evaluation of four LNG reserve stations of city gas is carried out combined with engineering cases.
