Abstract
Classical queuing models assume that each incoming user is accepted into the system if there is at least one free space in the queue and is served in a certain order. However, frequently in real systems, users may be impatient and leave the system after some waiting time if their service has not begun. Another kind of practically important and interesting queues is so-called ticket queues. In such queues, each arriving user receives a numbered ticket and observes the number of the user being served, which is broadcast on a display panel. In a ticket queue, no physical queue is formed. Thus, based on information about the difference between his own number and the displayed number, the user decides whether to balk or wait for service. In contrast to the usual queues with balking users, the balking user in ticket queues leaves the system physically, but his number remains in the queue.
We consider a ticket queueing system with a finite buffer of capacity. Arriving users obtain a ticket for service but may balk the system with the probability depending on the queue of tickets ahead of customers. Tickets issued to users remain in the ticket buffer whether they participate or not. The server is unaware about the presence of users in the system and spends some time for their service even the respective user already left the system. In this paper, good reviews of relevant research are presented and the stationary distribution of the considered system is analyzed.
