Usage mission completion probability model for complex systems
Complex system usage mission completion capability is researched considering spare replacement maintenance during mission. Firstly, this paper classifies the usage mission of weapon systems. Secondly, the state transition process of a spare system is analyzed through Markov process under given maintenance supply strategy, and the mission completion probability is understood as the distributing function of the spare system sojourn time at working state within fixed time. And its numerical value is got by total probability decomposition and renewal process. Thirdly, the complex system mission completion probability is got by analyzing the mission reliability relationship among spare system, equipment and weapon system. Finally, the curves of mission completion probability varying with mission time and work time are plotted by numerical calculation, and the influence of mission time on mission completion probability is analyzed.
