Abstract: A cognitive model for survivable system with a multilayer cognitive ability was proposed, and based on high-order multi-type π calculus, combining formal modeling of cognitive model with quantitative analysis of cognitive performance, thus can obtain the quantitative evaluation of system cognitive performance after formal modeling of system operation state, system service and internal structure. A cognitive model for survivable system with a multilayer cognitive ability was proposed. Based on high-order multi-type π calculus, formal modeling of cognitive model for survivable system in two aspects was taken. By using the tool MWB, the tests were achieved about system availability, instantaneous availability, steady-state availability and high-priority tasks throughput in different attacks.
