Study On Green Manufacturing Operation Model And Its Implementation Methods

Green Manufacturing (GM) is a kind of modern manufacturing mode with the full consideration of resources consumption and environmental impact. It is an international cutting-edge area formed by the deeply crossing of management science, manufacturing science and environment science. And it embodies human sustainable development strategy in modern manufacturing industry. As a kind of advanced manufacturing concepts, the final purpose of GM is the application and implementation in enterprises and to make enterprises harmonize the economic benefits and environmental benefits.The GM implementation and operation in enterprises cover a wide range, from management to technology, from design and manufacturing to distribution, maintenance, recycling and disposal. Then the implementation process is very complicated and the investment is large. Thus, the support of related model and methodology is of great significance. In this thesis, the GM operation model and implementation methods are studied.Firstly, based on the discussion of GM technology connotation and system framework, a GM operation model of five-layer structure is proposed, including enterprise strategic goal, enterprise operation objectives, product design process main line, product life cycle main line and supporting systems. And the five subsystems of the operation model are discussed in detail.On this basis, the application roadmap of GM operation model for three dimensions including general, industries, life cycle is proposed. General dimension includes general model, industries model and enterprises model. Industries dimension is a set of representative industries of different GM characters. Life cycle dimension is specific description of every stages of product life cycle from the GM view.Then, the construction of industrial GM operation model is presented. The typical electromechanical manufacturing industry (machine tool industry, electronic industry) is selected for the discussion of industrial GM operation model. The GM operation models of the two industries are constructed, which respectively include three key systems i.e. green design, green process and recycle treatment.Based on the proposed GM operation model, the GM implementation guiding principle, the construction of enterprises GM operation model and GM implementation methods system are presented and the main attention is focused on some key problems, such as, GM strategy selection, green technology portfolio selection and GM implementation risk assessment. The strategic factors system of SWOT analysis is constructed for GM strategy selection, and quantitative analysis is realized by the combination of AHP and SWOT analysis. With the consideration of synergetic benefits between different green technologies, a decision making model is proposed for green technology portfolio selection. A combined fuzzy statistical matrix and Bin fuzzy matrix method is put forward for GM implementation risk assessment.Finally, the GM operation model and its implementation methods are preliminarily applied in Chongqing Machine Tool (Group) Co., Ltd, and provide important reference and guidance for GM implementation, which has achieved a better application effect.
