Multi-state reliability modeling and simulation of system with self-adjusting function

In order to figure out problem of system with self-adjusting function, multi-state of system with self-adjusting function was analyzed, a method for degradation procedure simulation was put forward, and model of reverse state transition was presented. Basing on above analysis and model, a multi-state Monte Carlo simulation model was established. At last, a case of space camera multi-state analysis was carried out, which not only verified the correctness of the model, but also provided many optimization suggestions for sub-system reliability parameter determination. It has provided a feasible way for reliability design and optimization in space equipment engineering.
