Study On Green Manufacturing Implementation Model And Implementation Methods For Custom-manufacturing Enterprises

Manufacturing industry is the main pillar industries of national economy. But the foundation of manufacturing industry in our country is weak; the innovation ability is not strong, and the consumption of resources and energy during manufacturing process is huge, accompany with severe pollution problems. Therefore, the idea of"developing green manufacturing, speeding up relevant technology application, promoting green manufacturing implementation"is be considered as one of the three thoughts leading the development of manufacturing written in National Outline for Medium and Long Term S&T Development (2006-2020)."Developing green manufacturing"is the complicated system engineering. It calls for both the emphasis on the green manufacturing technology, and the attention to the common technology (such as the green manufacturing implementation model, implementation method, standard system, the basic data, etc.). At the same time, along with the production focus transferring form product to customer, customization production mode gradually become dominant production mode adopt by more and more enterprises. Therefore, it is necessary to do the research on green manufacturing implementation model and implementation methods for custom-manufacturing enterprises based on the characteristics of customization production.With the foundation of National Key Project of Scientific and Technical Supporting Programs of China (Project No. 2006BAF02A01), National Natural Science Foundation of China (Project No. 50605066) and Chongqing Natural Science Foundation, this paper studied on green manufacturing implementation model and implementation methods for custom-manufacturing enterprises. The details of the contents are presented below.First, aiming at the implementation of green manufacturing needs the guiding of the implementation model, based on the analysis of the existing research and the basic idea of green manufacturing, the concept of the green manufacturing implementation model for custom-manufacturing enterprises is analyzed. On this basis, combining the characteristics of customization production and the special demand of custom-manufacturing enterprises, a green manufacturing implementation model for custom-manufacturing enterprises is proposed. Due to the complexity of the implementation model, the system views, including functional view, product life cycle views, manufacturing process view, structural view, resources and environment influence views, of the implementation model is established. By the system views, the implementation model can be understood from different aspect. In order to facilitate the implementation, a three-layer framework of the model, including goal layer, product life cycle layer and supporting layer, is construct. And the technical systems are expounded.Second, the methodology, the system engineering method and the general ideas of the green manufacturing implementation method for custom-manufacturing enterprises is discussed. And then, focuses on the product scheme green design method for custom product and the environmental impact of manufacturing process analysis method. On the product scheme green design method, a case-based product scheme green design method for custom product is designed. For this method, the customer demand analysis method, case-based product scheme matching method, product scheme environmental attributes analysis method and customized product design scheme selection method with a focus on integration of environmental attributes are studied respectively. The basic idea of the method is that choose the similar case according to the customer demand, and design the product scheme with a focus on integration of environmental attributes(resource consumption, environmental impact, easy disassemble, etc.), then design the product in detail. On the environmental impact of manufacturing process analysis method, taking Eco-indicator 99 as a reference standard, an analysis model for environmental impact in manufacturing process is presented. Then, the solving processes of the model are briefly described and the environmental impact assessment matrix of a cellular manufacturing process is established. The model can be used to calculate the environmental impact value of manufacturing process which is compatible with the eco-indicator 99. This value can be used to improve the environmental friendliness of manufacturing process and product design programs.Finally, analyzed the application program for a certain type of electric switchgear product custom-manufacturing enterprise based on the research results, and introduced the implementation.
