The Computer Simulation for Queuing System

� Abstract—The queuing system is a typical problem of discrete event system, and the computer simulation is a quite effective way for solving the queuing problem and analyzing the performances of the queuing system. This paper provides the step of the research of the computer simulation and necessary mathematical algorithm by studying the single-channel and multi-channel queuing system based on the payment system of the minitype super-market. Keywords—The computer simulation, the queuing system mathematical model. HE computer simulation is a method that demonstrates dynamtically the structure and the behaviors of a system with computer in order to evaluate and predict the effect of the behaviors of some system and provide information for decision. It is an effective way to solve complicated practical problems. The queuing system is the most typical problem in the discrete event system, and computer system, communication system and transportation system are all typical tangible or intangible queuing system. As a result of the widely used queuing system, the queuing character, the queuing regulation, the service organization become more and more complex so that the parsing method nearly can't be obtain. The computer simulation is a quite effective way for solve the queuing problem and analyzing the performances of the queuing system, which construct a real system model with computer program, and attain the performances and the characters changing with time through computation. With the computer simulation, the cost of the development of the system can be reduced, and the safety of the experiment and the debugging, thus it will bring great society effort and economic effort. In the queuing model, data units are often considered as customs and CPUs, transmission lines, channels and terminals are thought as queue. This is just a queuing model. Because input, computation, transmission, storage and output are discrete in time field, it is also called discrete queuing model. In real life, waiting in queue is a common phenomenon, which makes people inconvenient .This paper takes the payment of minitype supermarket as a example to discuss the computer simulation for the single-channel and multi-channel queuing system.
