ABSTRACT: This paper is dedicated to the presentation of the single-channel waiting line systems
with Poisson arrivals and exponential service times.They represent stages of customer flow
management processes. Waiting systems are stochastic mathematical models and they represent the
describing base of the waiting phenomena, service processes, prioritization, etc. Mathematical
models of queuing theory present interest in modeling, designing and analysing of nowadays
information networks. Increasing trend of their development and emergence of new network
technologies, impose new requirements regarding the development of new mathematicals waiting
models. In this paper we merely present the single-channel waiting line model, with example on a
fast-food restaurant.

Key words: customer flow, queuing theory, waiting system, waiting line, efficiency
