RCM3 methodology applied to the cooling system of a Land Military Vehicle with the application of Colored Petri nets

The main objective of this paper is to create a maintenance model for Land Military Vehicles, based on the study of reliability, maintainability, and availability throughout its life cycle. One other objective is the possibility to identify the logistical needs for the supply of spare parts for a military mission because of the number of engine hours that are expected to be operated. In the example shown, the model is applied to a cooling system for a Land Military Vehicle. The Reliability Centered Maintenance 3 (RCM3) methodology is applied to the physical system. Through simulations of the model of Colored Petri Nets (CPN), it is possible to investigate distinct scenarios and investigate the performance of the system. From the application of the RCM3, it is possible to conclude that this is a robust system, with several components with few failures, and in the case of the components with more recurrent failure modes, they present high Mean Time Between Failures (MTBF) values. It allows simulating the real situation and supports decision-makers in the dynamic formulation of the maintenance plan. It will be also possible to identify the logistical needs for the supply of spare parts for a military mission taking into consideration the number of engine hours that are expected to be operated in an operational mission.
