Network-based Computer System Reliability modeling to explore the reliability, availability and security of network-based computer systems used in life-critical applications such as avionics, nuclear power plants, automobiles and industrial chemical processes. Reliability-based Network Computer Systems provides a basic concept of reliability modeling and address new challenges in modeling the reliability of computer network-based systems, as well as new trends, capabilities and limitations. It includes various methods of modeling the dependence: stochastic processes, Markov and semi-Markov model, the response-time distributions, stochastic Petri-net-based modeling formalism, andMonte Carlo simulation model. Reliability-based Network Computer Systems provides students and researchers with a detailed picture of reliability models and analysis techniques.
