Multichannel queueing systemwith a finite buffer, a lockout of an input flow, and a knockout of customers from the buffer

A multichannel queueing system with a finite buffer, a lockout of a semi-Markovian input flow, and a knockout of customers from the buffer by a first customer arrived into the system over the period when the input flow is unlocked is considered. The periods of lockout and the periods when the input flow is unlocked have an exponential distribution with different intensities. The main stationary characteristics such as a queue distribution, a loss probability, and a mean sojourn time are found.
