大型船舶物資補給理論搬運時間優(yōu)化問題研究
[Abstract]:With the increasing change of military pattern, there is more and more demand for the construction of large ships that can sail at sea for a long time. Material supply is an important factor affecting the endurance and maneuverability of this kind of ship. It is particularly important for large ships sailing at sea to complete the material supply in a relatively short time. The optimization of material supply theory handling time is studied. It is of great theoretical and practical significance to discuss the optimization model and calculation method. Based on the material supply of a large ship, this paper establishes a theoretical transportation time optimization model, which mainly optimizes the material supply process from two aspects: the flow control of the transfer link and the selection of the transportation strategy. Its decision-making goal is to minimize the handling time. The process of material supply is abstracted from the two factors of material type and supply port quantity. The optimization problem is divided into four cases: single material single supply port, single material double supply port, multi-material single supply port and multi-material double supply port. For the case of single material supply, the problem of network maximum flow is reduced to the problem of network maximum flow. Ford-Fulkerson algorithm is used to optimize the calculation and maximize the system traffic, that is to say, the handling time is the shortest. For the case of multi-material supply, the optimization content is the combination scheme of mixed shipment from wharf to ship, that is, the transportation strategy, which belongs to the NP-hard problem, which is similar to the job shop scheduling problem. Based on the event-driven idea, the optimization model is established. The mixed shipping scheme from wharf to ship is taken as the variable, and the minimum handling time is taken as the objective function. Genetic algorithm is used to solve the problem, the variables are encoded by matrix, and the matrix transformation method is proposed to legitimize the illegal chromosomes after crossing. Because the standard genetic algorithm is easy to fall into local optimization and the convergence is slow, this paper improves on the basis of the standard genetic algorithm. Finally, based on a specific example, the effectiveness of the model and algorithm is verified, and it is proved that the improved genetic algorithm can get better solution and accelerate the convergence speed than the standard genetic algorithm.
