摘要资源、环境、人口是当今人类社会面临的三大主要问题，特别是环境问题，正对人类社会的生存与发展造成严重的威胁。制造业是国民经济持续发展的基础产业。它过去是、现在是、在可以预见的将来仍然是经济增长的主要动力。什么样的产品是绿色产品，如何客观、科学的对产品进行绿色度综合评价，还没有统一、权威的看法。客观、正确的度量产品的绿色度，已变得非常重要。43915

一个合适的评价体系和方法不仅影响到评价结果的准确性，而且也会影响企业生产计划的合理制定和实施。本文比较了几种常见的系统评价方法，根据产品的特性，提出了应用模糊层次分析法对工程机械产品进行绿色度综合评价。

本文主要进行了以下几个方面的研究:

1. 详细分析工程机械产品在其生命周期的各个阶段与环境的关系，找出可能对环境造成的负面影响和产生的原因。同时研究工程机械产品绿色度综合评价指标体系的制定原则，确立合理的评价指标。

2. 构造工程机械产品绿色度综合评价系统的层次模型，确立各个层次的评价指标。建立同一层次评价指标的权重判断矩阵，计算各评价指标的组合权重。对最底层评价指标建立隶属函数，确定相应的隶属阈，进行无量纲化处理得出隶属度。最后应用线性加权法给出产品的综合评价值。

3. 根据模糊层次分析法评价产品绿色度的原理和步骤，采用 VB6.0作为开发工具，以SQL2000开发了功能完善，界面友好、使用简单的产品绿色度综合评价系统。应用该评价系统计算出电除尘器的绿色度综合评价结果和各项指标值。根据电除尘器的绿色度综合评价结果和各项指标值的分析，为电除尘器的进一步绿色化提出建议和意见。

Abstract

Nowadays,natural resource, environment and population are being three major problem that human society are confronted with. Especially the environment problem is threatening the survival and development of human society. Manufacturing industry as the basic industry of a country’s economy persistently keep the national economy developing, it is still not the main factor that keep our economy improving in the past and our living days but in the anticipated future. But, what kind of product is green product, how to objectively, scientifically make a comprehensive evaluation for the green degree of product, still have no unified, authoritative view. Objective and scientific measure of the green degree has become very important.

A suitable evaluation system and method not only affects the accuracy of the evaluation results, but also affects the reasonable formulate and implement of the production plan. This paper makes a comparison of several common system evaluation method, according to the characteristics of the product, and put forward the application of fuzzy analytic hierarchy process to mechanical and electrical products to to make comprehensive evaluation for green degree of product.

This paper mainly studies the following several aspects:

1. Make a detailed analysis of the relationship between each stage of mechanical and electrical products in its life cycle and the environment, identify the possible factors that have impact on the environmental.at the same time,study the principle of making the comprehensive evaluation index system for the green degree of mechanical and electrical pruducts and establish the reasonable evaluation index.

2. Construct the hierarchical model of the comprehensive evaluation system for the green degree of mechanical and electrical pruducts. establish the evaluation index.for every layer. Establish the judgment matrix for the weight of the evaluation index of each level,ccalculate the combination weight of every index.establish membership function for the bottom index,identify the membership thresholds.
