The Master of Science in Industrial Engineering and Operation Research is geared towards training young engineers to become operational specialists in designing, installing and managing industrial production and service systems, taking into account scientific, technological, economical, organisational and human factors. It is clear that many companies, both small and large, are eager to recruit these engineers. Internationally, experience with master’s programmes in industrial engineering shows that graduates quickly grow towards responsible leadership functions. Furthermore, IEOR engineers are not only found in industry but also in many organisational systems of society such as government, health care and hospitals, public service, law enforcement, transport and traffic systems, et cetera. It is also a core discipline in less traditional engineering environments: consumer-directed service companies, supermarket chains, retail companies, health services, consulting, etc. IEOR engineers are often responsible for the operational aspects of organisations in functions like production manager, head of development, supply chain manager … and are found in all levels of the management. They also function as specialists (‘methods engineer’) in supporting departments of large companies and international corporations. Notable examples of what IEOR has to offer in today’s society can be found on www.iienet.org, the web site of the Institute of Industrial Engineering (IIE) which is the international professional organisation of engineers in this discipline. The organisation of European students of Industrial Engineering and Managements (ESTIEM) can be found on www.estiem.org.
