[Abstract]:The problem of environmental pollution in manufacturing industry has aroused extensive attention of scholars at home and abroad, and technology of green process design method research for energy saving and emission reduction products, the manufacturing industry, and has important theoretical significance and application value. In this paper, the research status at home and abroad on the summary, proposed and in-depth research of part process technology. Green failure analysis the mode of relevance modeling and process around the parts process failure mode correlation modeling, process design, hierarchical planning and process parameters of regeneration, multi-objective decision making research on green technology scheme, multi-objective green satisfaction assessment techniques, and examples of application in the process design of complex Auto parts products, on the proposed theory to verify the feasibility, method and technology.
The organizational structure of the full text is as follows:
In the first chapter, we summarize the research status of the key technology of part process design and the related methods of green manufacturing process design at home and abroad, and point out the deficiencies of the current green manufacturing process planning and design technology, and give the main research work and organization structure of this paper.
The second chapter: Aiming at the defects existing in the failure mode of the fuzzy semantic application process, proposes a knowledge expression method can consider failure process and failure mode of fuzzy semantic relevance. Fuzzy information using fuzzy set theory to quantify the process failure in the assessment of expert experience and language, through the fuzzy TOPSIS technology improvement the impact strength of various failure modes. By using the theory of decision making trial and evaluation laboratory, construction of failure mode directly affect the association graph, failure mode of synthetical effect matrix, calculated each kind of reason of the failure mode, to realize the reasonable expression of fuzzy association process semantics of the failure mode, which provides the basis for the subsequent process failure the application of knowledge in the process design.
The third chapter: according to the product design in the process of product development and design process of parallelism, and product design information by the progressive law of rough tapering, the product design process is divided into conceptual process layer, process layer preliminary and detailed process of modeling layer. Each layer of the main process activities by the integrated definition of modeling theory, implementation planning the three step of hierarchical process, improve the degree of parallelism of product design and process design. Then, the use of technology in the production practice of failure knowledge, the fuzzy correlation failure model based on the optimized process scheme of the manufacturing process to achieve reliable regeneration, is helpful to the process design and manufacturing forward to improve the reliability.
The fourth chapter: the process of constructing the grey model of green manufacturing, the process parameter optimization process into multi attribute decision process. Using the triangular fuzzy number of uncertainty of green manufacturing evaluation experts, fuzzy knowledge is not accurate, the laboratory test and evaluation method of decision process to establish the green evaluation index directly affects the incidence matrix and the comprehensive effect of each evaluation index matrix, obtained the reason degree and centrality, and correlation analysis of green process evaluation index, and according to the influence degree of weight distribution. Considering the group profit maximization and individual regret minimization, using the DEMATEL-VIKOR theory of green process parameter decision, green process parameters considering decision maker subjective preference or compromise process parameters set, and determine the optimal process parameters of the control green priority implementation Multi-objective green optimization for manufacturing process parameters.
The fifth chapter: the weight of green process decision is rational and actual physical meaning is difficult to determine the problem, proposed scheme product process analysis technology. The subjective preference and decision feedback based on mutual information green through the user layer, with preference capture layer, decision-making layer, project evaluation layer and the candidate layer decomposition refinement, multi-layer architecture process green analysis. Using the trapezoidal fuzzy number of decision fuzzy knowledge processing based on decision target preference acquisition, number preference letter established to reflect the decision-maker's subjective information, build a physical programming model with fuzzy semantics green process scheme. Through satisfactory information to decision makers and process. The mutual feedback, Fuzzy Physical Programming and mutual feedback process for green satisfaction based on decision.
The sixth chapter: research the application of part process failure correlation modeling and scheme green analysis technology in the process design of automotive parts and components, and verify the feasibility of the theory, method and technology.
The seventh chapter: summarize the research results of the full text, and look forward to the future research work.
