Evaluation of redundant configurations in assembly lines with fractional tasks

Abstract Assembly lines with fractional tasks increase the throughput a better workload balancing among stations. The possibility to share between two consecutive stations can also support design of assembly redundancies tasks. redundancy allows reacting short failures or variations in processing time. This paper proposes framework and control lines. first problem concerns modified mixed-integer linear programming model used for allocation line Then, this research policies manage shared Finally, simulation evaluates performance proposed methods handle uncertain times. numerical results show potential improvements limited number redundancies. main concern reduction time work process.
