Spare parts optimization model of warship formation based on gravitational search algorithm

Aiming at the actuality of Integrated Support Engineering(ISL) of ships and taking the operational readiness of ships as a research goal, the optimization model of warship formation's spare parts was established with the goal of minimizing the cost-effective rate, considering the requirement of operational availability of warship formation and the constraint of the cost of spare parts. The steps of solving problem based on Gravitational Search Algorithm(GSA) was given. An example of the application of GSA was given too. The validity of the model is verified, which provides an important reference for the warship formation's configuration optimization of spare parts.
