Abstract: In this paper we study some basic concept of queuing theory and provide brief overview of queuing theory. We analyze the basic component of queuing theory and different type of distribution that are used to analyze a queuing model. The importance and requirement of state dependent queuing model also explained. Finally some basic model of queuing theory, performance measures is discussed and methodologies used to analyze such model are explained.
Keywords: State dependent model, Vacation model, Breakdown model, Maximum entropy principle.
