基于可拓评价的产品回收等级分类

Extension Assessment Based Product Recycling Classification

为提高产品的回收效率,本文讨论了产品的回收分类问题,归纳出影响产品回收的若干指标,提出了基于可拓评价的回收分类方法。针对产品回收分类的若干指标因素采用定性与定量相结合的方法,将回收的产品划分为四个级别,并借助可拓数学这一工具,采用简单关联函数确定指标权重,由此确定待评回收产品关于各类别等级的关联度,评定结果按它与各等级集合的关联度大小进行比较,关联度越大,它与某等级集合的符合程度就越靠近,从而为回收产品的分类提供定量化的依据。最后与现有方法进行了比较,结果表明是合理可行的。

In order to improve product recycling efficiency, this paper discusses the problem of product recycling and its classification. It induces several impact factors for the product recycling. The paper also proposes an extension assessment based approach to classify the recycled products. Through the combination of the qualitative analysis and quantitative analysis, the recycled products are classified into four grades. By the use of the extension mathematics, the weight of the factors can be determined through the correlation function, which is used to calculate the correlation degrees of the recycled products for each grade. Comparing the correlatiom degree of a product with that of each grade set, the products can be classified accordingly. Compared with other methods, this method is proved to be more feasible than the others.
