Warning to those planning to attend ICCPMA 2016  

September 17, 2016


We would like to call attention to a fact that ORSJ is neither involved in the International Conference for Computational Physics, Mathematics and Applications (ICCPMA 2016) nor responsible for its organization. More precisely, ICCPMA 2016 used the name of ORSJ without consent; besides, while the conference website uses the postal address of the ORSJ's office as if the conference organizing body, named Institute of Information System & Research Center, is located at the same address. However, it is all a complete lie. Namely, ORSJ exclusively uses the address and has never agreed to support or organize the conference.


We have first recognized the unauthorized use of the name and address of ORSJ very recently after receiving several inquiries from potential participants of the conference. After a brief investigation, we found that ICCPA 2016 also uses the name of a professor in Japan without his consent. In light of those facts, the conference seems to be a fraud, which has nothing to do with ORSJ. We hope that those who plan to attend the event will not suffer from any damage caused by this illegal activity.

In addition to such pursuits as research on OR theory and the development of methodologies, the ORSJ explores the practical use of methods applicable to specific problems occurring in the world of business and government offices. It also actively promotes exchanges of information among its members as well as interaction on an international level.

5. Publications
  1. Communications of Operations Research of Japan, the journal for ORSJ members, is published periodically in Japanese. Each issue has a special feature section consisting of clear, readily understandable explanations about OR theory and applications pertaining to a particular subject. The journal's contents also include articles written by leaders in this field, regular columns on selected topics, case studies, and updates on ORSJ activities.

    "Journal of the Operations Research Society of Japan" is a professional journal issued four times a year. From 2010, JORSJ are freely accessible at ORSJ webpage.

6. Research presentation forums and symposiums
  1. The ORSJ holds forums every spring and fall to present the results of research. The spring session is in Tokyo, while the fall event is held elsewhere in Japan.

    The research forums feature not only a conventional presentation format but also a "paper fair" structure that emphasizes discussion.

    Special lectures and symposiums are held during the research forums.
