Abstract: This paper considers a Markovian queueing inventory system with c servers and optional self-service facility, driven by an inventory under the (s, S) protocol. When an arrival occurs, if both an idle server and free inventory are available, then service by a server is initiated. If a customer on arrival finds all servers active but free inventory available, then he can either wait for the server (join the waiting line) or go for a self-service. A modified case of the framework has been analysed by changing the presumption that in the event when an arriving customer finds all the servers active, but a few inventories free will choose to have self-service. Here also we obtain steady-state probabilities and express a cost function in terms of some important performance measures. We made a point to point investigation on recycle time. A cost optimisation problem has been stated and numerically solved. Also, the impacts of certain parameters on a few performance measures are moreover outlined numerically.
