TL;DR: An exact analysis is given of the steady state behavior of a queueing model for one possible operating rule for a technical control facility, the situation where one and only one of the servers may periodically leave the facility.
Abstract: In this paper we develop a queueing model for one possible operating rule for a technical control facility. As suggested in reference [1] a military technical control facility can be considered as a multi-server queueing system. One possible operating rule, the situation where one and only one of the servers may periodically leave the facility, has not been considered previously in the queueing theory literature. In this paper, we give an exact analysis, as well as presenting several approximations, to the steady state behavior.
