Abstract

The root cause of mission safety problem is the loose combination of safety and mission, and the inadequate traction and restraint of safety by missions. Therefore, an aviation equipment mission safety model is established to study the safety events during mission execution. The definition of mission safety (MS) and the mathematical foundation of the instability domain is given based on the Safety Structure Theory (SST) and three-way decision-making theory(3WD). Factors are used to express the SHEL system and mission system, and then the atomic action factor space (AAFS) is developed to “bear” the state space of the target mission profile, and the atomic SHEL space (ASFS) is developed to “bear” the state space that describes the constraints of the mission system on the SHEL system. The mapping from ASFS×AAFS to ASFS is established, which could transform the evolution of MS into the spatial dynamic trajectory in ASFS. This model can be used in the construction of mission safety analysis platform, the evaluation and prediction.
