- Abstract
Multi-mission phased mission system (MM-PMS) is an extension of phased mission system (PMS) which is required to complete more than one missions for a period of time. Missions in MM-PMS usually have following characteristics: they have different mission starting and duration times; they share common components but with different combinational requirements; they have unequal occurrence probabilities. Therefore, reliability modeling and evaluation of MM-PMS is more complicated than that of PMS. This paper presents a general methodology based on the extended object-oriented Petri net (EOOPN) for mission reliability modeling and evaluation of MM-PMS with these characteristics. The proposed EOOPN model for MM-PMS includes five sub-models depicting MM-PMS at different levels of granularity. To demonstrate the effectiveness of the proposed model, mission reliability evaluation results of a simple MM-PMS case by EOOPN simulation methods are compared with those by binary decision diagram (BDD). Results show that the EOOPN model is suitable to depict the dynamics and to evaluate the reliability of MM-PMS.
