基于熵权法—灰色评价法的炼化低温热利用技术评估研究

将熵权法与灰色综合评价法相集成,形成了用于评价炼化低温热利用技术的新方法。该方法在低温热利用技术评价指标体系的基础上,利用熵权法获得指标权重,并通过求取灰色关联度建立了炼化低温热利用技术评价模型,减少了人为主观认识对评价结果的影响,使评价结果更加客观和具有指导性。通过实际案例,给出了该模型的计算流程及评价方法。

Study on the Assessment of Refinery Low-Temperature Heat Recovery Technology Based on Entropy Method and Grey Integrated Evaluation Methods

By combining entropy method with grey integrated evaluation methods, a new method for the assessment of refinery low-temperature heat recovery technology has been formed. Based on the evaluation index system of low-temperature heat recovery technology, the index weight is obtained by entropy method, and the evaluation model of refinery low-temperature heat recovery technology has been established by obtaining grey association degree. Since the influences of artificial factors are reduced, the evaluation result is more objective and instructive. According to the real case, the calculation procedure and evaluation method of the model are introduced.
