基于熵权法的制造业绿色产品达标条件下的综合选优

Manufacturers' Green Product Choice Optimization Based on Entropy Method Industry

在满足制造业绿色产品判定标准的产品中,各自不同的经济、技术、环保特性的产品取向仍然存在。本文在对达标条件下,产品选优的必要性及产品优势进行分析的基础上,提出了适于权衡不同优势的基于熵权法赋权的一种动态综合选优评价模型,其使用便于实现资源能源的优化配置,是对完善制造业绿色产品评价系统的重要补充。该方法根据各项指标值的变异程度来确定指标权数,这是一种客观赋权法,同时也充分体现了权数可变的思想,克服了以往绿色产品评价过程中存在的均一性赋权,即权数固定导致评价缺乏柔性的局限。

The green products in manufacture industry still differ from each other in terms of economics, technology, environmental friendliness, though they all reach the criteria of limitation. This paper expounds the necessity for product choice optimization and provides a model based on information entropy to judge different advantages of product groups. The model is a dynamic and synthetic assessment for realizing optimization deploy of resources and energy. It is an important complement to modifying and improving the evaluation system of green products. The weight is constructed on the mutant degree of index on different attribute, so, it is an objective assessment method. At the same time, the method sufficiently reflects the thought of variable weight and overcomes the disadvantage of homogeneity weight in assessment process of green products, which lead to the limitation of losing flexibility in green products.
