Mission Reliability Simulation of Time Redundancy PMS with Multiple Missions
Haiyue Yu, Xiaoyue Wu · 2018
For phased mission systems (PMS), sometimes there are several missions need to be completed during its mission time. These missions are not always independent due to common components. Moreover, the system within a phase may need to keep working for only a minimal length of time less than the phase duration, so a time redundancy exists in the phase. Most existing works on PMS do not considered this two factors. This paper proposed a simulation method based on extended object-oriented petri net (EOOPN) to get an approximate solution of such kind of time redundancy PMS with multiple dependent missions. A threelevel modeling procedure with five EOOPN general models is defined describing the mission execution process. A simplified example is introduced to explain the use of the method.
