Abstract

This research is motivated by conflicting condition of satisfying forward rotation shift allocation and available workers constraint. Shift scheduling generally considers number of workers as input parameter that represents the demand especially for service industry. As consequence, shift workers will apply short rest time because of violation of forward rotation shift allocation to satisfy number of workers constraint. This condition could decrease workers satisfaction of their schedule and also influence workers performance. The proposed model has develop 2 stages procedure, i.e. (1) Shift schedule development using initial number of workers, (2) adjusting number of workers to minimize violation of soft constraint. Numerical example shows that the developed shift schedule results global optimal solution for small problem. It is better to adjust the number of workers by decreasing female worker and increasing male workers, because flexibility of male workers to be assigned in all shifts. However, the proposed model can recommend the composition of male and female workers to maintain the advantages of female workers.
