For tackling job scheduling problems encountered with discrete manufacturing system for 380km/h motor bogie, Object-oriented Petri Net based Job-Shop Cell Controller System (OPNCC) was brought forward identifying categories of all objects within cell control model, describing relationship between categories, analyzing and recognizing cell control logic through the dynamic behavior of physical objects and introducing control decision and strategy into the control logic of as designed OPN model, thereby constituting a complete object-oriented cell control model. With improved genetic algorithm, it can offer dynamic optimization to balanced production of multiple work pieces on several machine tools so that the machine tools can be utilized to a maximum extent.

This research project aims to study and develop the differential evolution (DE) for use in solving the flexible job shop scheduling problem (FJSP). The development of algorithms were evaluated to find the solution and the best answer, and this was subsequently compared to the meta-heuristics from the literature review. For FJSP, by comparing the problem group with the makespan and the mean relative errors (MREs), it was found that for small-sized Kacem problems, value adjusting with “DE/rand/1” and exponential crossover at position 2. Moreover, value adjusting with “DE/best/2” and exponential crossover at position 2 gave an MRE of 3.25. For medium-sized Brandimarte problems, value adjusting with “DE/best/2” and exponential crossover at position 2 gave a mean relative error of 7.11. For large-sized Dauzere-Peres and Paulli problems, value adjusting with “DE/best/2” and exponential crossover at position 2 gave an MRE of 4.20. From the comparison of the DE results with other methods, it was found that the MRE was lower than that found by Girish and Jawahar with the particle swarm optimization (PSO) method (7.75), which the improved DE was 7.11. For large-sized problems, it was found that the MRE was lower than that found by Warisa (1ST-DE) method (5.08), for which the improved DE was 4.20. The results further showed that basic DE and improved DE with jump search are effective methods compared to the other meta-heuristic methods. Hence, they can be used to solve the FJSP.
