Fuzzy Reliability Analysis Of Network Systems

Network systems are having been widely used in communications, transportation, engineering management. With the development of the complex communication system, computer network and electricity network, the calculation of network reliability problems appeared, although new large-scale complex network has many already reliability calculation. However, in the network, entering the information and system state have some degree of uncertainty, this uncertainty includes both randomness and fuzziness. The reliability of traditional analysis methods can not meet the large and complex that contains fuzzy system reliability analysis and design of the need to make on the fuzzy reliability of network systems.This article is first series-parallel network system, for example, in the division of the fuzzy state on the basis of a mathematical model, discussed several key indications, including the fuzzy reliability, fuzzy failure rate, average life expectancy of fuzzy and fuzzy residual life based on fuzzy state is given the average life expectancy and remaining life of the new fuzzy definition, on this basis to consider a large two terminal network system, using a computer algorithm come true the minimal path and not make the calculation method of combining fuzzy reliability calculations, large two terminal network system for fuzzy reliability index discussed, a calculation of fuzzy large-scale two terminal network reliability.
