Example Embodiment
[0116]Examples:
[0117]The invention selects a standard job shop benchmark example to test the performance of the algorithm. Based on the standard calculation examples La01~La20, construct the percentage of the machine buffer capacity to the number of processed workpieces. For example, the scale of the calculation example La01 is 10x5, which means that the number of workpieces is 10 and the number of machines is 5; the percentage of the machine buffer capacity to the number of processed workpieces is 10. %, it means that the cache capacity of each machine is 1.
[0118](1) Experimental parameter settings
[0119]The initial population size, cross-mutation probability, and number of iterations of the improved genetic algorithm will all affect the convergence of the algorithm. In this paper, the population size is set at 50-200, and the number of iterations is 50-200. , The convergence of the algorithm is better when the number of iterations Gmax=100. The specific parameter assignments of the...
