The Research And Development Of The Comprehensive Green Degree Evaluation Of Electromechanical Product Based On Fuzzy Analytic Hierarchy Process

Resource, environment and population are the three main problems that human beings must face today. Especially the worse and worse environment is threatening the existence and development of human beings. Although manufacturing industry is the backbone of a country's economy, it is not only the main cause of the resource depletion but also of the environment pollution. Many countries have devoted a lot of manpower and material resources to researching and devising green products. However, until now there is no consistent and typical criterion on what is a green product and what is not. A good method to evaluate the comprehensive green degree of the products impersonally and exactly is very needed.An appropriate evaluation system and method will not only influence the correctness of the result of the evaluation, but also the rational establishment and implementation of the manufacturing plan of the enterprise. According to the characteristics of the electromechanical products, FAHP(Fuzzy Analytic Hierarchy Process) is presented to evaluate the comprehensive green degree of the electromechanical products.There are some main problems discussed in this dissertation as follows:1. Detailed analysis of the relation between the environment and the electromechanical products in its full life cycle, the reasons of the negative impact which the electromechanical products may do to the environment, and the research on the principles of the comprehensive evaluation establishment. Finally to present the very appropriate evaluation indexes.2. Establishment of the hierarchy model of the comprehensive green degree evaluation system, and to present the evaluation indexes of every class. Constructing the judging matrix, and to calculate every index's weight To build the functions of the degree of subordination of the bottom indexes, and the establishment of the evaluation thresholds. Having the indexes none-dimensionally , and to educe the degree of subordination of every index. Finally to get the result of the comprehensive evaluation using the linearity-weighted-sum method.3. To develop a prototype system of Ihe comprehensive green degree evaluation of the electromechanical products. The system is developed by ObjectARX2000 & Visual C++ 6.0 and embedded in AutoCAD2000. It can not only evaluate me comprehensive green degree of the electromechanical products , but also provide much "green knowledge" and help the engineers to make green design and green manufacturing. The comprehensive green degree of the F177 ESP(ElectroStatic t>reciprtator) designed and manufactured by Zhejiang Feida Electromechanical Company is evaluated.
