Based on the theory of multiple attribute decision making, an algorithm of comprehensive and comparative evaluation for product environmental adaptability is presented. A program is built and used in an example of design improvement. The result shows that the proposed method and algorithm are practical and effective to the development of green products.展开更多

After classifying the impact factors, with grey-system theory, the evaluating grey-groups and their whitening weighing functions are defined;the grey-cluster analysis of each classified impact is performed;based on analyzing results, the calculating method of classified impact index is given. By range of action, the impact classes are grouped to three groups - global impact, regional impact, and local impact;the calculating methods of grouped and overall impact index are presented. Finally, an application example of comparative choice of a category of products - three materials, steel, aluminum and engineering plastics is given.展开更多

In the choice of materials, this paper presented a method for the re-combination of recycled materials. In the recovery of the product it proposes the establishment of recycling system, and expounds the concept upgrade recovery. Design and manufacturing of green products and green recycling industry is the two most important link in green circular economic system, whether or not the coordinated development of the two sectors, is the key to the success or failure of the strategy of sustainable development.展开更多

The concept of green economy with low power consumption and low pollution is becoming the focus of global attention. This article reviews the development of green supply chain management （GSCM）, and briefly introduces the current methods of GSCM. In order to implement GSCM in the round, this paper recommends the life-cycle analysis, and proposed GSCM methods which the different types of companies should adopt.展开更多

It calls for not only a green revolution in our ways of production and ways of life, but also a restructuring of the ＂knowledge-oriented＂ model of intellectual production that has served as bedrock to support the single-minded mentality of developmentalism. One of the possible routes to arrive at a new Weltanschauung is what I have termed as the ＂living wisdom＂ that can help to explicate the inexplicables by existing social theories. I argue in this paper that the Chinese living wisdom offers a nutshell view of how traditional resources can be made accessible for us to respond to current unprecedented chaJJenges facing htunamty. It is as much a best oppommky in the ＂metropolitan moment＂ for a ＂China＇s representation＂ as for other civilizations, cultures and nations, such as the ＂eco--social time＂ in primitive societies, the ancient European philosophies on ontology and cosmology, and the rejection of sagehood and intellect by Zhuangzi.展开更多
