基于再制造域空间的废旧机械装备多目标优化再设计理论与方法研究

The remanufacturability of used machinery equipment is the foundation and basis for redesign. Due to the damage diversity and residual life uncertainty of machinery equipment, and the influence from redesign process to the quality, capacity and secondary service life of components, the remanufacturability evaluation of used machinery equipment is a feasible space, not an exact value. However, the present research has focused on quantitative description of remanufacturability, not much effort was put on dynamic cooperative relationships between the remanufacturability and redesign process. Thus, this project proposes a concept of remanufacturability space for integrating remanufacturability into redesign process, and establishes a representation model for remanufacturability space to reveal the forming regularity and system characteristic. On the base of that, a muti-objective optimization redesign model is developed based on the cooperative rule between remanufacturability space and muti-objective optimization redesign. Finally, a combinatorial optimization technology for used machinery equipment redesign is proposed. The research achievements can contribute to promote the remanufacture of used machinery equipment to regularization, and can also assist to perfect the subject system of remanufacture.

再制造性是废旧机械装备再设计的基础和依据。然而，由于机械装备零部件服役后损伤程度和剩余寿命的差异性，以及再设计对零部件再制造质量、性能和二次服役寿命的影响，导致废旧机械装备再制造性不是一个确定的可行值，而是一个可行域空间。但是，现有研究侧重于再制造性的定量化描述，忽略了再制造性与再设计过程的动态协同关系，难以有效指导废旧机械装备优化再设计。为此，本项目将再制造性融入废旧机械装备再设计全过程，提出废旧机械装备“再制造域空间”的概念，并对再制造域空间进行表征，揭示再制造域空间的形成规律和系统特性；研究再制造域空间与多目标优化再设计的映射规则，建立多目标优化再设计模型；提出基于组合优化的多目标优化再设计方法，并开展再设计验证和应用研究。本项目将形成一套基于再制造域空间的废旧机械装备多目标优化再设计理论与方法体系，促进废旧机械装备再制造的高效规模化推广，并进一步完善再制造的学科体系。

针对零部件服役后损伤程度和剩余寿命的差异性导致的废旧机械装备再制造性界定，以及再制造性与再设计过程的动态协同关系难以有效指导废旧机械装备优化再设计的难题。本项目提出了基于物元理论与工匠经验知识重用的废旧机械装备再制造性评估技术，构建了包括技术、经济、资源环境等目标域以及装备、部件、零件等过程域的废旧机械装备再制造域空间体系；将再制造域空间融入再设计全过程，提出了基于公理设计的目标域与过程域的多域空间映射技术，构建了基于目标级联法的废旧机械装备多目标优化再设计模型；分析了再制造目标域指标与过程域指标的关联关系，以及面向成本、碳排放、效率等优化目标的传递、反馈、协同控制技术，提出了基于自适应教与学优化算法、粒子群优化算法等的废旧机械装备多目标优化再设计方法。在此基础上创建了一套基于再制造域空间的废旧机械装备“多域空间+双向定制”公理化再设计理论与方法体系。本项目部分研究成果已在企业开展了应用，对促进废旧机械装备再制造的高效规模化推广，完善再制造的学科、应用体系具有重要意义。
