The study of optimal preventive maintenance interval is an important topic primarily because it is an efficient way to maximize operational availability of a weapon system using only small resources. A study of this kind is handled by using simulation methods. In this paper, we propose a modeling method of weapon systems that may be used for optimal preventive maintenance interval and analyzed optimal alternatives. The Modeling and Simulation (M&S) method is quite useful compared with the mathematical approach, since M&S is a stochastic analysis. It considers the randomness of the failure rate, repair time and operation schedule. Using this method, therefore, allows us to achieve more reliable results from other mathematical approaches. First, we analyze the mathematical approach using the existing papers. Second, we introduce a model, called the General Model, which reflects the operational concept and maintenance policies of a general weapon system. It may be customized to fit specific systems. Third, we present a specific case using UAV (Unmanned Aerial Vehicle) system, and customize that model. Finally, we arrive at an optimal solution by simulating that model.
