Asymptotic diffusion analysis of the retrial queuing system with feedback and batch Poisson arrival

The mathematical model of the retrial queuing system \(M^{[n]}/M/1\) with feedback and batch Poisson arrival is constructed. Customers arrive in groups. If server free, one arriving customers starts his service, rest join orbit. service times are exponentially distributed. customer whose completed leaves system, or reservice, goes to method asymptotic diffusion analysis proposed for finding probability distribution number condition growing average waiting time accuracy approximation obtained.
