产品级再使用的绩效测度

产品级再使用绩效测度有助于总结再使用的经验,加强停用产品的资源化管理,实现产品的最大再利用价值,提出了从技术先进性、绿色性、经济性和心理因素4个方面测度产品级再使用全过程绩效,建立了产品级再使用子系统和特征矩阵,提出了基于谱范数的测度方法,该方法充分利用了产品级再使用全过程的指标信息,并在不同阶段给予指标不同的权重。针对绩效测度指标过多的问题,提出了两阶段的层次分析法,在多指标权重确定中具有应用价值,另一方面也解决了专家的权威与共识问题。以电视再使用为案例,验证了提出的理论和方法能有效测度再使用绩效,并进行了结果分析,给出了再使用建议。

Performance Measurement on Product Level Reuse

Performance measurement on product level reuse helps to summing up reuse experiences,enhancing reclamation to disable products,and achieving maximum reuse values.Measuring on the whole process performance of product level reuse from the functional,green,economic and psychological factors are presented.A product level reuse subsystem and its feature matrix are built to analyze and evaluate reused products.Aiming at the complexity of reuse dates,the measure method based on the spectral norm is proposed.The method takes advantage of the index information on the whole process of product level reuse,and gives different weights to indicators in different stages.The two-stage AHP method is proposed aiming at the too many performance measurement indicators and the problem of the expert＇s authority and consensus.The example of TV reuse illustrates that the proposed theory and method can effectively measure the reuse performance.Finally,the results are analyzed and reuse proposals are given.
