Abstract

The paper gives a review of the literature related to the stability measures and describes a new concept with exhaustive simulation results. Predictive production schedules are calculated by a scheduler based on a genetic algorithm, hybridized with a modified Giffler&Thompson algorithm. By applying the proposed sched-uler and executing the resulted schedules by simulation, the solution methods for stability-oriented resched-uling described above can be profoundly tested and analyzed. Evaluation of several scenarios of the re-scheduling threshold and the timing of rescheduling are presented in a case study. The system to be (re)scheduled is a five-machine test system with machine breakdowns. The results show how the investi-gated rescheduling parameters and the disturbances generated into the system affect the efficiency and the stability of the schedule execution
