考虑能耗的废旧产品拆解序列规划与混流拆解线平衡综合建模及优化

Disassembly sequence planning and disassembly line balance of obsolete products are two important processes in remanufacturing and recycling fields. Nowadays, many scholars study them independently. In fact, they are mutual relevance and impact. Integrating these two processes, i.e., disassembly sequence planning and disassembly line balance, is able to improve production efficiency and reduce energy consumption. This research focuses on basic theories and key technologies for comprehensive modeling and optimization of disassembly sequence planning and mixed-model disassembly line balance. The research contents are presented as follows: (1) based on the Petri nets, disassembly sequence planning model of multi-products is established; (2) the optimization model of disassembly line balance is built based on the stochastic programming; (3) Comprehensive optimization model for disassembly sequence planning and mixed-model disassembly line balance is obtained based on multilevel programming; (4) Based on the characteristic of the established mathematical model, this research designs an intelligent algorithm integrating artificial intelligence technologies to solve it; and (5) By taking typical automotive components as an example, and by using the developed prototype system, this work illustrates the effectiveness of proposed theories and methods. This research would provide a novel and effective scientific method for the analysis of the disassembly process and provide decision support and technical support for related sustainable manufacturing issues, e.g., design for disassembly and green disassembly process design.

废旧产品拆解序列规划和拆解线平衡是再制造或回收利用中的两个重要作业流程，当前许多学者对它们进行了独立研究。然而，现实中两者即相互关联又彼此影响，整合拆解序列规划和拆解线平衡这两个流程能提高生产效率降低能耗。本项目结合Petri网和智能规划理论，研究考虑能耗的拆解序列规划和混流拆解线平衡综合建模及优化的基础理论和关键技术。主要内容包括：（1）基于Petri网的多产品拆解序列规划模型构建；（2）基于随机规划的拆解线平衡优化模型构建；(3)基于多层规划的产品拆解序列规划和混流拆解线平衡综合优化模型构建；（4）基于建立的综合优化模型特征，设计融合人工智能技术的混合算法并进行求解分析；（5）针对典型汽车产品的拆解实践，开发原型系统并验证提出理论与方法的有效性和合理性。本项目研究为产品拆解过程分析提供新颖有效的科学方法，还为产品可拆解性设计和绿色拆解工艺设计等可持续制造领域提供决策支持和技术支撑。
