Abstract: Abstract This paper embeds safety sensitivity analysis into model-based systems engineering (MBSE) design, constructs a safety sensitivity analysis framework based on system design models, and establishes a model-driven safety design process and sensitivity analysis procedures oriented to complex tasks. The moment-independent importance measure analysis method is adopted, and the measure values are used to directly identify the key risk factors that play a leading role in the task. This study addresses the problems of unknown or difficult-to-accurately-fit new single-machine failure rate distributions under multi-system integration, interactive interference between variables, and the difficulty in identifying key variables in multi-system coupled tasks, thereby providing a clear target for subsequent scheme optimization and risk management and control.
