Abstract:

The fleet level repair plan optimization is directly related to the effective completion of various combat training tasks and the scientific use of maintenance cost. Based on a combined periodic and dual control repair model, considering the fleet system utilization, warship effectiveness attenuation characteristics and the expectations and preference of decision makers, the expectation effectiveness evaluation model of the fleet system is constructed by prospect theory. Further, the maximization of the fleet system effectiveness value function is as the objective, considering the constraints such as the maintenance period, inter-period repair, maintenance cost, equipment effectiveness and availability ratio, the fleet level repair plan optimization model is established. The mixed coding particle swarm optimization (PSO) algorithm is used to optimize the model. The results show that compared with the traditional method, this method has higher efficiency and itemized efficiency of fleet, and better coordination between warship use and maintenance. It can provide a strong technical support for the scientific preparation of fleet repair plan and the effective performance of naval missions.

Key words: fleet, class repair plan, equipment system, expected effectiveness, effectiveness attenuation
