Based on Color Petri-net Modeling and Estimate for Task Reliability of Complex Weapon System

Aiming at the task reliability of complex weapon system, an idea of stratified modeling and estimate method based on color Petri-net with memory token was proposed. All tasks in system, reconstructive number and required resources for every task can be modeled by color Petri-net with memory token. Based on the state of required resources and accumulated working time, the system can identify whether the tasks could be completed and obtain the reliability indexes of each task. An application of example for Field Air-defense C3I system shows that the method is feasible. The method suits to multi-task and re-configurable systems task reliability modeling and estimate.
