Operation research

The term Operation Research (OR) related to military operations during the Second World War. Scientists used various techniques to deal with strategic and tactical problems during the war. After the war military OR group scientists tried to apply OR techniques to civilian problems relating to business, industry and research development. During the 1950s educational institutions introduced OR in their curricula. Today service organizations such as airlines, railways, hospitals, libraries and banks employ OR to improve their efficiency.

Operation Research in India

In India, operations research came into existence with the opening of an OR unit in 1949 at the Regional Research Laboratory in Hyderabad. At the same time another OR was set up at the then Defense Science Laboratory to tackle the problems of stores, purchase and weapon evaluation. An OR unit under Professor P.C. Mahalonobis was established in 1953 in the Indian Statistical Institute, Kolkata to apply OR methods in national planning and survey. Operation Research Society of India (ORSI) was formed in 1957 and its first conference was held in Delhi in 1959. For academic studies, the first M.Sc. course on OR was started by Delhi University in 1963. At the same time, Institutes of Management at Kolkata and Ahmedabad introduced OR in their MBA courses.
