Assembly Line Balancing Problem-1 ConsideringFatigue Balance of Workers

Abstract:

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.
