中文摘要
      基于快速全身评估法对所有的作业姿势进行风险评估,考虑不同作业元素优先关系、不相容和同工位等约束,提出融合作业时间和作业姿势相互影响的工位累计疲劳度,构建最少工位数和最小工位累计疲劳度标准差的多目标优化模型,保证装配线工位少且疲劳度均衡.采用基于优先权重的编码,设计多目标粒子群算法,最后通过实例证明本方法的合理性与有效性.
英文摘要
      The posture risk of each task is calculated by using rapid entire body assessment (REBA). Accumulated fatigue of station (AFS) is proposed for cumulative fatigue of all tasks at one station considering time and task posture. In order to ensure least stations and balance of fatigue, a multi objective optimization model is constructed to minimize the number of stations and AFS with precedence relationship constraints and task assignment restrictions. The multi objective particle swarm optimization algorithm coded by precedence is designed. The rationality and effectiveness of proposed method is proved by a real case.
