多目标决策灰色关联投影法油气回收绩效评价

Assessment Model of Economic Performance of Oil Vapor Recovery Based on Grey Relation Projection Method of Multi-criteria Decision

针对现有油气回收方法缺乏量化性比较评价的问题,采用模糊数学中的灰色系统理论和工程优化中的多目标决策思想,建立了基于多目标决策的灰色关联投影法油气回收绩效评价模型.利用该模型对现有四种油气回收方法的指标数据进行综合量化分析,结果表明,该模型的量化评价结果与现有文献的非量化评价结果是一致的,证明模型是有效可信的,从而为石化企业油气回收的方法选择和方案设计提供决策参考.

Aiming at the problems that the lack of quantitative comparison evaluation of existing oil vapors recovery methods,the assessment model of economic performance of oil vapor recovery based on grey relation projection method of multi-criteria decision was established by using fuzzy mathematics in the gray system theory and multi-objective decision-making ideas in engineering optimization.The model comprehensive quantitative analysis of the indicator data of the existing four kinds of oil vapors recovery methods.The results show that quantitative evaluation of the model is equal to the non-quantitative evaluation of existing literature and prove that the model is effective and credible.Thereby it provides decision-making reference for petrochemical enterprises to select gasoline vapors recovery methods and design scheme.
