Asymptotic analysis of the flow of repeated requests in system MMPP|M|<» with repeated requests
In this article, the Queueing system with unlimited number of facility is considered. The Markov modulated process, controlled by the Markov chain k(t) with infinitesimal generator Q = ||qj ||, enters into the input of such system. Every customer comes into any of the vacant server, where he is served during a stochastic time distributed according to the exponential law with the parameter ц. After service, the customer leaves the system with probability r-1, and with probability r the customer comes back in it for repeated service The problem is to study the flow of repeated requests to the system during the time t. Using the method of initial moments, analytical expressions are found for the first and the second moments of the number of repeated requests to the system during the time t. For more detailed research of this process, the method of asymptotic analysis is proposed in a condition of a growing service time. It is shown that asymptotic characteristic function of a number of repeated requests into the system during the time t has the Poisson distribution with the following parameters: a = M {i(t)} = rKt, G
= M{(i(t) - a)
} = rKt, where к is defined as к = -2- RAE, 1 - r [RQ = 0 E is an unit column vector, and the row vector R is determined by the system Keywords
