QUEUING SYSTEM | ETS075 |

**Aim**

The purpose of the course is to introduce methods to predict the real-time behaviour of service systems, especially for telecommunucation systems.

*Knowledge and understanding*

For a passing grade the student must

- Solve problems in elementary queuing theory and queuing network theory
- Use simple simulation tools

*Skills and abilities*

For a passing grade the student must

- Use simple queuing models to estimate the real-time properties of a system
- Use discrete event simulation to study the performance of a system
- Be able to interpret measurements and make estimations

**Contents**

The course treats real-time properties of communication systems. The students learn to predict the performance of systems, which also gives the ability to improve and optimise systems.

The course contains an overview of elementary queuing and queuing network theory and also introduces discrete event simulation. In queuing theory methods to calculate the average time a customer spends in a queue and the blocking probability are treated. In queuing network theory Jackson networks are studied. Discrete event simulation using a general programming language is studied.
