Based On Structured Element Research Model Of FM/FM/·Fuzzy Queueing Theory

Method based on fuzzy structural units of the queuing theory with fuzzy parameter, the parameters in the classical model of queuing theory system is fixed, not depict real life well. With the development of the society, life rhythm to speed up the randomness is becoming more and more popular, is more and more uncertainty, difficult to control. So this paper studies the ambiguity of queuing theory. First study the queuing system with fuzzy variable input rate, M/M/1/?namely when customers with parameters as negative exponential ? arrived in system, but is queued waiting for is an uncertain factor, then the effective ?e arrival rate of input process is a random variable, said that with the fuzzy structure element method makes it easier to calculate. Then, the queuing M/M/-model.Under the condition of the fuzzy parameters are discussed,the customer arrival time and service time are fuzzy Numbers.Using the combined fuzzy expansion and natural expansion principle. Fuzzy queuing model of the main indicators of solving transformed the arithmetic of fuzzy multiple functions.Get fuzzy queuing model FM/FM/·under the balanced distribution of average captain, the average sojourn time And the membership function and related indicators.
