Endogenous Queue Number Determination in G/M/s Systems

Research output: Contribution to journalArticle



This paper presents a model for the endogenous determination of the number of queues in an G/M/$s$ system. Customers arriving at a system where $s$ customers are being served play a game, choosing between $s$ parallel queues or one single queue. Equilibria are obtained for risk-neutral and risk-averse customers. With risk-neutral customers, both a single queue and multiple queues are equilibrium states, and there is scope for mixed strategies. When risk-averse customers are considered, there is a unique single queue equilibrium. These results are discussed and suggestions for further research put forth.
