摘要: Several different models for predicting coverage in a fault-tolerant system, including permanent, intermittent, and transient errors, are discussed. Markov, semi-Markov, nonhomogeneous extended stochastic Petri net computing developed. Two types of events that interfere with recovery examined; methods modeling such events, whether they deterministic or random, given. The sensitivity system reliability/availability to the parameter various error-handling strategies investigated. It is found policy attempting upon detection an error (as opposed automatically reconfiguring affected component out system) can actually increase unreliability system. >
