摘要
柔性Flow-shop调度问题(Flexible Flow-shop Scheduling Problem,FFSP)是一般Flow-shop调度问题的推广,由于在某些工序上存在并行机器,所以比一般的Flow-shop调度问题更复杂。为了有效地解决柔性Flow-shop调度问题,用遗传算法求解,给出了一种改进的编码方法,能够保证个体的合法性;并根据编码方法提出了矩阵解码方法。最后以某汽车发动机厂金加工车间的生产调度实例进行仿真,通过比较表明了算法的有效性。
Flexible Flow-shop Scheduling Problem （FFSP） is expansion of general flow-shop scheduling problem.It is more complex than general flow-shop scheduling problem because there are parallel machines on some operations.In order to efficiently solve this problem,a new method solving flexible flow-shop scheduling problem based on genetic algorithm is proposed.A new improved encoding and decoding with matrix method for the flexible flow-shop scheduling problem are proposed.These operators can easily keep the feasibility of solution.Finally,an example of production scheduling problem for metalworking workshop in a car engine plant is simulated.Through comparison ,the results show the effectiveness of the algorithm.
