摘要

本文分析了人机协同拆解线平衡问题,该问题与传统的拆解线平衡问题有很大的不同。在人机协作拆解线上,多个人和机器人在每个工作站执行拆解任务。由于产品质量和人的能力等不确定性,人机协同拆装线平衡问题是一个动态优化问题。我们考虑到产品质量和人员能力的不确定性。此外,动态优化问题需要在不断变化的环境中快速准确地跟踪Pareto最优解集,迁移学习已被证明是合适的。为此,提出了一种基于个体迁移学习辅助的进化动态优化算法来解决人机协同拆装线平衡问题。该算法采用基于个体的迁移学习技术进行经验重用,加快了初始种群的生成,提高了解的收敛速度。最后,基于本文生成的一组问题示例,将所提算法与多个竞争算法在平均倒代距离和平均超体积方面进行了对比分析,验证了所提算法在人机动态协同拆解线上平衡问题上的有效性。结果表明,该算法在处理大规模问题时具有良好的性能。

Individual-Based Transfer Learning for Dynamic Human-Robot Collaborative Disassembly Line Balancing
This paper analyzed the human-robot collaborative disassembly line balancing problem, which is significantly different from the traditional disassembly line balancing problem. In a human-robot collaborative disassembly line, multiple people and robots perform disassembly tasks at each workstation. Due to the uncertainties such as product quality and human capabilities, the human-robot collaborative disassembly line balancing problem is a dynamic optimization problem. We take into account the uncertainty of product quality and personnel capabilities. In addition, dynamic optimization problems require fast and accurate tracking of Pareto’s optimal solution set in a changing environment, and transfer learning has been proven appropriate. Therefore, an individual-based transfer learning-assisted evolutionary dynamic optimization algorithm has been developed to handle the human-robot collaborative disassembly line balancing problem. The algorithm uses an individual-based transfer learning technique to reuse experience, which accelerates the generation of the initial population and improves the convergence speed of solutions. Finally, based on a set of problem examples generated in this paper, the proposed algorithm is compared and analyzed with several competitors in terms of the mean inverted generational distance and the mean hyper-volume, verifying the effectiveness of the proposed algorithm on the dynamic human-robot collaborative disassembly line balancing. The results show that the proposed algorithm has good performance in large scale problems.
