On the fuzzy scheduling for flow shop jobs by using genetic algorithm

Deals with fuzzy scheduling for flow shop jobs. In this scheduling problem, we employ a fuzzy penalty cost function for the delay time of the deadline of a job. The evaluation of job flow (ordering) is done by evaluating some penalty costs for the jobs. To select the best job flow, a genetic algorithm is used. However, under fuzzy evaluation, its solution is not unique and fuzzy valued. Finally, the fuzzy solutions as job flows are shown in a fuzzy Gantt chart.
