Summary

Simulation modelling involves the development of models that imitate real-world operations, and statistical analysis of their performance with a view to improving efficiency and effectiveness. This non-technical textbook is focused towards the needs of business, engineering and computer science students, and concentrates on discrete event simulations as it is used in operations management. Stewart Robinson of Warwick Business School offers guidance through the key stages in a simulation project in terms of both the technical requirements and the project management issues surrounding it. Readers will emerge able to develop appropriate valid conceptual models, perform simulation experiments, analyse the results and draw insightful conclusions.

Author Biography

Stewart Robinson is a Senior Lecturer in Operational Research at Warwick Business School. With more than 15 years experience of simulation and its practice, he has consulted for many national and international organizations. His teaching and research focus on simulation and the practical application of operational research. These are subjects on which he has published three books and more than 40 articles.
