中文摘要：
针对机械产品设计过程中通常考虑产品寿命终结阶段（End-of-life,EOL）报废处理过程的可拆卸性、再制造性、环保性等单个绿色质量因素影响,导致机械产品的回收拆解中可重用、回收零部件由于拆解过程费事、费力、经济性差无法回收重用或因回收重用价值不大导致零部件被直接废弃,造成严重的环境污染。从回收拆解作业效率、回收拆解作业收益和回收拆解作业环境影响3个角度对产品EOL报废处理过程中的产品综合关键绿色质量进行综合分析和度量,在此基础上建立面向EOL的综合关键绿色质量指数的机械产品设计绿色多准则优化模型。根据机械产品设计绿色多准则优化模型,利用改进强度Pareto进化算法（Strength Pareto evolutionary algorithm 2＋,SPEA2＋）求得面向EOL的综合关键绿色质量指数的Pareto稳健优化解集,并筛选出具有最优面向EOL的综合关键绿色质量指数的产品回收拆解设计方案。应用所提方法对永磁同步无齿曳引机产品设计进行绿色多准则优化,证明其在工程应用中的正确性与高效性。
英文摘要：
In complex mechanical product design,the disassembly,remanufacturing,environmental and other individual factors of the end-of-life（EOL） processing are considered.The time of product useful life might be shorten or the product might be discarded as useless,because of time and costs of the operations by recycling of materials and reusing of components.It also makes serious environmental pollution when components of products are improperly disposed.A mathematical model is established based on synthesis key-green-quality index which is composed of the operation efficiency,the economic costs and the environmental impact by the measurement and analysis of EOL processing.An optimization process using strength Pareto evolutionary algorithm 2＋（SPEA2＋） is put forward on the foundation of the analysis and measuring of the characteristics of EOL processing.Based on the mathematical model of product optimization design for EOL processing,the Pareto set for the multi-objective optimization problem is obtained using the multi-objective optimization algorithm.The multi-objective Pareto-optimal solutions are facilitating operations of the EOL phase.The efficiency and effectiveness of the proposed method is illustrated by the green multi-criteria optimization for product design project of gearless traction machine.
