Abstract:

The deployment capability of a single ship depends on its maintenance structure (MS), while the usage requirements of the fleet has an important influence on the development of the MS of a single ship. For the usage requirement of the fleet, the MS is optimized by the method of time series. From the aspect of changing the intervals of the depot-level maintenance, the optimization model of the MS under the condition of a fleet is established. The model involves a combinatorial optimization problem and is achieved by the genetic algorithm. Then a fleet example is used for solving and validating the model, and the optimization results show that, after optimizing and adjusting the MS of every ship in the fleet, the fluctuation of the number of deployable ships is clearly reduced and the time points of the small number of deployable ships are basically eliminated, thus the overall deployment capability of the fleet is improved.
