[Abstract]:The flow shop scheduling problem exists widely in the actual manufacturing, and the research of this kind of problem has always been a hot issue of concern in the manufacturing and academic circles. The research on this problem can effectively improve the production efficiency of the flow shop, reduce the inventory of in-process products, and shorten the late period. In today's manufacturing industry increasingly fierce competition, customer demand increasingly personalized and diversified era, appears more and more important. Most of the flow shop scheduling is NP-hard problem. In recent years, the meta-heuristic algorithm based on natural law has shown a good effect in the process of solving the problem. The swarm breeding algorithm studied in this paper is a new optimization algorithm which combines the idea of population optimization and local search and has been successfully applied to many combinatorial optimization problems. In this paper, the single-objective, multi-objective flow shop scheduling and multi-objective hybrid flow-shop scheduling with limited buffers are studied in turn by combining theory and practice. The details of the research are as follows. The main results are as follows: (1) when solving the single objective permutation flow shop scheduling problem, a local search mechanism combining variable neighborhood search and simulated degradation algorithm is proposed to simulate the behavior of worker bees, and an improved colony reproduction algorithm is proposed. Then by solving the related benchmark examples, a better optimization effect is obtained, and the effectiveness of the algorithm is verified by comparing with the results in other literatures. (2) Multi-objective optimization is a hot topic in recent years. In this paper, a multi-objective displacement flow shop scheduling problem is studied for three typical objectives: maximum completion time, total process time and total delay. Based on the idea of Pareto, a colony reproduction algorithm for multi-queen bee is proposed. The clustering distance is used to increase the dispersion of the non-branching solution and the search space of the algorithm. A variable neighborhood search algorithm based on Pareto and a cross operation based on memory mechanism are designed. The effectiveness of the proposed algorithm is verified by example testing and comparing with the current optimal non-dominated solution set in the literature. (3) the mixed flow shop scheduling is the most practical one in the flow shop scheduling problem. On the basis of the above research, this paper aims at the practical application of engine 5C parts processing. The multi-objective hybrid flow shop scheduling problem with limited buffer is studied based on colony reproduction algorithm. The coding method based on the replacement workpiece is adopted, and then the feasible scheduling is generated by the complete scheduling construction program, and the better scheduling results are obtained. The validity of the algorithm is verified by testing and comparing with the existing examples in the literature. Finally, based on the above-mentioned research results, the corresponding prototype system is developed, and the whole paper is summarized, and the in-depth research of swarm algorithm in flow shop scheduling is prospected.
