Abstract:

Shipboard helicopters are an important force in amphibious landing operations, how to carry out flexible and efficient dynamic scheduling of shipboard helicopter fleet for complex and dynamic battlefield environment and mission requirements is of great significance to enhance the combat effectiveness of amphibious formations. Aiming at the dynamic uncertainty during the execution of shipborne helicopter combat missions in the context of amphibious landing, a dynamic scheduling optimization method based on the demand window strategy is designed. Firstly, considering the resources of multi-ship platforms and the end-to-end combat-sustainment task integration, based on the constraints of combat resources and multi-stage operation timing, the mathematical model of shipborne helicopter mission dynamic scheduling is constructed with the multi-objective function of landing time consumption and mission adjustment cost. In order to solve the above model, a dynamic scheduling strategy based on perturbation event simulation and a dynamic scheduling algorithm based on forbidden search are designed to generate the optimised initial value of the algorithm based on the dynamic scheduling strategy, a decentralised search and a centralised search operation based on conditional judgement are introduced to optimally solve the constructed initial value in the search process. Finally, through the amphibious landing operation thought, comparing the difference of optimisation results under different scheduling strategies, verifying the reasonableness of the scheduling strategy, the algorithm is more efficient in computation, the convergence effect is better, and the scheduling results have less deviation from the original plan. It provides a reference basis for the dynamic adjustment of the shipboard helicopter operational program in the high-intensity confrontation environment.
