摘要
因机器人在从事同种工作上的效率差别,机器人生产线的平衡问题除涉及工序的排列组合外,还涉及工作站不同机器人的指派问题。文章提出将工序排列和机器人指派问题编码形成组合染色体,同时解决两个组合优化问题。其中使用Petri网络建立工序关系,依据其关系矩阵进行随机染色体的调整。相对递归式机器人指派方法,该方法优化结果更优,为复杂机器人自动化生产线的工作站设计提供了一定依据。
Because of the productivity difference of different robots processing the same work,robot assembly line balancing problem involves procedure combination and robot assignment in workstation.A combined chromosome including procedure arrangement and robot assignment is proposed to solve the combination and optimization problems at the same time.Procedure relationship is built with the Petri Net,whose relation matrix can be used to adjust the random chromosome.Compared with recursive type robot assignment method,the method proposed in this paper expand the solution space.Thus,the optimization results better.This paper provides certain basis to workstation design of the complex robot automatic production line.
