BI–DIRECTIONAL WORK-SHARING IN ASSEMBLY LINES WITH STRICT AND FLEXIBLE ASSEMBLY SEQUENCE
Work-sharing between stations in assembly lines can reduce cycle time and improve throughput rate. This research studies an assembly line in which tasks may be shared with their immediate upstream or downstream stations. The balanceability term is first defined as the ability of an assembly line to achieve a perfect balance (identical workload in all workstations) via work-sharing. Then, the conditions for balanceability of lines are investigated, assuming that all tasks can be shared. The identity of the tasks to be shared to this end is then given. Next, a situation where only some of the tasks can be shared, either downstream or upstream, is addressed and the optimal balance with respect to the cycle time objective is obtained. Finally, the cost associated with work-sharing is considered. Consequently, MILP model formulations to minimize the cycle time under a given limited budget are developed for the cases of strict and flexible assembly sequence of tasks. Experimentation to evaluate the performance of the formulations and the effect of the problem parameters on the run time is conducted.
