A Novel Mathematical Model for Manpower Scheduling in Break (Relief) Times in Mixed Model Assembly Lines

Abstract

AbstractIn real industries there are some limitations on the number of workers and in some situations it is unavoidable to schedule employees for break times to minimize labor cost. In this paper, the problem of manpower scheduling in break times for employees working in mixed model assembly lines (MMALs) is investigated, which has not been studied to the best of our knowledge. We assume three breaks a day, one for lunching and two breaks for short resting. It is also essential to attend the station by the minimum number of workers while manufacturing desired rate of production
