Many members of ISIR have significantly advanced the goals of the organization through their general contributions to knowledge, the formation of professionals, the promotion of international cooperation and/or exemplary practice. In effort to recognize such individuals who have advanced the goals of ISIR through contributions to the profession and service to the organization the Society founded a Fellows program in 1996. New Fellows are announced at the International Symposia.


Ruud Teunter, University of Groningen, The Netherlands


Geert-Jan van Houtum, Eindhoven University of Technology, The Netherlands


Stefan Minner, Technische Universität München, Germany


Ton de Kok, Eindhoven University of Technology, The Netherlands

Ton de Kok’s academic career is highly devoted to inventory control. After a mathematics study at the University of Leiden he embarked on a PhD project on Production-inventory control models on which he got his PhD in 1985. Thereafter he started working at the Center for Quantitative Methods (CQM), a consulting company on inventory control within the Philips Company. After 5 years he moved to Philips Consumer Electronics, but Ton got more and more interested in research and he moved to the Technical University of Eindhoven, first as part-time and later as full professor in Operations Management in 1992. Since that time he has written over 75 papers in international scientific journals, supervised many PhD students, most on inventory control. In 2004 he was Edelman Award Finalist as member of the Philips Semiconductors team and in 2006 he received ISIR’s Service Award. Ton’s most known contribution is on multi-echelon inventory systems, where he developed new evaluation and optimization methods. Finally, Ton also started a company, called Chainscope, where he is presently CTO. So all in all a very varied career, but in almost all his endeavours inventories played an important role.

The combination of rigor and pragmatic considerations in his papers over the years are really impressive. He has been a regular participant of the ISIR Symposia and acted in several roles in the ISIR’s community.


Attila Chikán

Prof. Chikán has been named a Fellow of ISIR for a number of reasons.  First and foremost are his contributions to the organization.  As founder of ISIR he realized his vision of international scholarly collaboration, enriching the research and lives of many colleagues.  As First Vice President and Secretary General, his leadership has sustained the life of the organization and provided great value to its members.   Prof. Chikán?s role in mentoring and developing students and colleagues alike extends far beyond his role in ISIR.  From the creation of a college to broaden and deepen the experience of university students to his collaboration with colleagues in research and publication, he has shared his knowledge, contacts, insights and time.  His influence has been felt from the classroom to the boardroom in government and in business.

The intellectual contributions of Prof. Chikán are significant as well.  His publications number in the hundreds.  His books and articles have influenced academics and practitioners alike.  Especially noteworthy is the interdisciplinary nature of his work.  By incorporating micro and macro views of economic phenomena, Prof. Chikán crosses boundaries to provide much deeper understanding of system behavior. Similarly, his melding of mathematical modeling and organizational behavior also enriches his insights.  His results don?t remain in academia.  They are incorporated into practice through seminars and workshops, Prof. Chikán?s consulting and his board memberships.  It is for his service to ISIR, mentoring of individuals, influence on the field and contributions to practice that Prof. Chikán is named Fellow of ISIR.


Jacob Wijngaard, University of Groningen, The Netherlands


Henk Zijm, University of Twente, The Netherlands

Rector of the University of Twente, The Netherlands had been named Fellow of the International Society for Inventory Research. This honor was bestowed for:
1. His important influence on inventory theory and management through his research, publications and professional presentations on production planning, inventory control, multi-echelon systems and flexible manufacturing issues.
2. His fostering of the development of colleagues and students by collaborating on research projects, supervising PhD. theses, publishing research findings jointly and in his administrative roles at the University of Twente.
3. His major contributions to practice with his work at Philips Electronics, consulting engagements and management seminars.
4. His support of the development of professional practice in research and application by taking leadership roles in academic and professional societies and, especially, for his service to ISIR where he has been an active presenter, has chaired individual sessions and is a member of the Executive Committee.


Louis Maccini
, The Johns Hopkins University, USA
Louis J. Maccini is by far the most active economist of his generation in the area of inventory research. He has contributed to our understanding of the linkages between inventory investment and pricing policy, adjustment costs, multi-period labor contracts, layoff behavior, production volatility interest rates, and so much more. While the Social Science Citation Index reports that his contributions have been cited more than 288 times, this is an understatement of his contribution to our discipline for he has inspired a cadre of graduate students at Johns Hopkins to focus their research on inventory behavior.

D. Clay Whybark
, University of North Carolina, USA
D. Clay Whybark is one of the most respected scholars world-wide in Production and Inventory Management (or Operations Management).
His works are standard references in academic publications and study materials in business education.
