Equipment Mission Safety Evaluation Method Based on Function-Structure

Safety is the eternal theme of aviation activities. With rapid development military technology and equipment construction, new requires safer more reliable management guarantees. The aim this paper to evaluate safety level in a single-stage mission. mission defined as capacity avoid unacceptable accidents during execution. A analysis framework constructed according logic mission-function-safety structure. profile ensures success by specifying functional requirements structure realizes adjusting scheduling resources. On basis, dependency network (FDNA) method improved study interaction failures between components specific state. numerical simulation for proposed analyze evolution relationship behaviors, which could obtain under different failure modes. case verifies application process. results revealed that assessment needs be evaluated with consideration profile. scale system conforms Weibull distribution attack It shown escalating risks will cause serious consequences.
