Abstract: Queuing theory employs mathematical analysis to determine the system's effectiveness measures. Such critical and effective measures are then used as data in the development of an optimization model for determining system efficiency and requirements. In this paper, we will discuss and provide the steps for developing the computer simulation model as well as the mathematical algorithms required to analyse the complex service network as queuing systems. A computer simulation is a realistic simulation of how a real-world process or system works over time. It is a very useful and valuable tool for analysing and evaluating any available or developed process. It can be used to learn, test, and evaluate the behaviour of many different types of problems. Simulation provides a low-cost, secure, and quick analysis tool with the necessary sensitivity analysis.
