Abstract


With global environmental issues increasingly serious , life- cycle assessment (LCA) as the key technology of green manufacturing caused widespread concern . However , LCA is only as tools for evaluation of the products environmental attributes in support of business decision-making has some limitations , because the enterprise is , after all, a profit institutions , in addition to environmental impact issues , economic issues and the sustainable development of enterprises is closely related to . Therefore , the LCA is integrated with other economic evaluation tools , and is one of the key ways to solve this problem to achieve environmental and economic benefits optimal . Will life cycle assessment and life cycle cost of integration and optimization . Review and summarize the first at home and abroad on the integrated study of the LCA and life cycle cost (LCC) , discusses the technical framework and methodology of LCA and LCC , and in the analysis of the basis of the existing difficulties LCA and LCC integrated integrated framework and research related to key technologies : (1) research products based on the unified Modeling language (UML) system modeling ; ( 2) evaluation of integrated design analysis integration algorithm based on a list of the time coefficient matrix ; (3 ) study the impact and establishment of integrated evaluation model based on AHP comprehensive impact assessment index system ; ( 4 ) build the manufacturing stage process planning . Build on the basis of the integrated evaluation environment with the cost optimization mathematical model , the use of multidisciplinary design optimization (MDO) algorithm in parallel subspace optimization (CSSO) algorithm to achieve integrated environmental and economic benefits of the overall product optimal . In addition, the manufacturing stage process route optimization problem , establish the environment and cost optimization model . 4135G diesel engine connecting rod processing routes , for example , the use of genetic algorithm toolbox in Matlab optimization process route , the feasibility and practicality of the verification environment and cost optimization model . Designed and self-developed prototype system LCA LCC1.0 detailed systems architecture design , functional design , the core technology and 4135G diesel engine as an example , demonstrates the results of the LCA LCC 1.0 system integrated evaluation and optimization verified the integration and optimization method proposed in this paper as well as the development of the system 's feasibility and practicality .
