摘要:With the development of global incorporation, mission of military equipments were getting diversification. In addition to traditional combat mission, they also needed to accomplish other tasks, such as disaster rescue. These transformations induced many difficulties to logistics support. This paper mainly focused on decomposing operational mission, and constrcuting mission-oriented reliability and maintainability parameter set for equipments. Consequrntly, RM model of baisc equipment combat unit was established, with multiple modeling theories and methods, such as phased-mission system and reliability block diagram, etc. This model could provide the foundation for operational mission-oriented support resource deployment and support efficiency evaluation.
