Task reliability optimization method for coupling damage trajectory dynamic joint prevention and control

Abstract

The invention provides a task reliability optimization method for coupling damage trajectory dynamic joint prevention and control. The method comprises the following steps: step 1, modeling a damage degradation trajectory in a task process; and 2, establishing and optimizing a task risk control strategy. The task reliability evaluation and optimization method based on environment impact-internal degradation damage trajectory coupling is innovatively constructed for the problem of multi-type fault risk coupling in a complex task environment on the basis of a joint dynamic prevention and control idea of associated damage. According to the method, on the basis of quantitative modeling and property analysis of a coupling damage trajectory, a detection-abortion combined control strategy for an aperiodic task period is designed, and a combined optimization method of a detection period and an abortion threshold value is developed. According to the method, the survival safety, the task reliability and the service economy of the task system in the complex competitive failure environment can be remarkably improved.
