通过对石化行业VOCs治理技术的分析,将层次分析法、熵权法与灰色关联度法相集成,形成了用于评价石化行业VOCs治理技术的新方法。该方法基于层次分析建立评价指标体系,利用熵权法获得指标层权重,并通过求取灰色关联度建立技术评价模型,减少了人为因素的影响,使评价结果更加客观和具有指导性。结合实际案例,给出了该模型的计算过程及评价结果。
Through the analysis of VOCs treatment technology in petrochemical industry, the methods of AHP, entropy method and gray relational degree are integrated to form a new method for evaluating VOCs treatment technology in petrochemical industry. The method establishes the evaluation index system based on AHP, obtains the index layer weight by using the entropy method, and establishes the technical evaluation model through the gray relational degree, which reduces the influence of human factors and makes the evaluation result more objective and instructive. Combined with the actual case, the calculation process of the model and the evaluation results are given.
