A Multiserver Queueing System with a Interruptable Semi-Markovian Input Flow of Customers and Customer Removal from an Infinite Buffer

A queueing system with a interruptable semi-Markovian input flow of customers and customer removal from a buffer is considered. New customers arrive at servers or at the buffer only during time intervals when the access to the system is open. Customers are lost when the access to the system is closed at the instants of their arrivals. The intervals when the access to the system is open and closed alternate and their lengths are exponentially distributed. The first customer arriving at the system at an open-access interval removes all the customers from the buffer. Stationary characteristics of the system are found for the case when the buffer has an infinite capacity.
