Dear Colleagues,  The aim of the IFORS Developing Countries Online Resources page is to offer the OR worker all publicly-available materials on the topic of OR for Development. It also aims to provide a venue for people who are working in the area to share their completed or in-process work, learn from others, and stimulate comments and discussions on the work. Regarding IFORS Developing Countries OR resources website, its regular updates - and your possible submission of "free" (not copyright protected) material, you might occasionally visit http://ifors.org/developing_countries/index.php?title=Main_Page. "Operational Research" (OR) is the discipline of applying advanced analytical methods to help make better decisions. By using techniques such as problem structuring methods and mathematical modelling to analyze complex situations, Operational Research gives executives the power to make more effective decisions and build more productive systems. The International Federation of Operational Research Societies (IFORS; http://ifors.org/) is an almost 60-year old organization which is currently composed of 51 national societies. Regional Groups of IFORS are: ALIO (The Latin American Ibero Association on Operations Research), APORS (The Association of Asian-Pacific Operational Research Societies), EURO (The Association of European Operational Research Societies), NORAM (The Association of North American Operations Research Societies). IFORS conferences are taking place every three years. IFORS 2020 will be celebrated in Seoul, South Korea (http://www.ifors2020.kr/). Thank you very much for your attention. With kind regards, best wishes, Gerhard-Wilhelm Weber PS: Feedback is welcome via gerhard.weber@put.poznan.pl.
