Here only some of the common applications are being mentioned: In such problems, various centres with their demands are given and various warehouses with their stock positions are also known, then by using linear programming technique, we can find out most economical distribution of the products to various centres from various warehouses. study with tentative formulation of the problem, which is reformulated over and again during the study. In operations research, problems are broken down into basic components and then solved in defined steps by mathematical has solved successfully many cases of research for military, the government and industry. Operation Research entails the application of the principles. This team was very success­ful and greatly contributed to the meticulous handling of entire operation and related problems of the operation. Now our aim is to learn how we can have better decisions.

Mathematical analysis for deriving optimum solution includes ana­lytical or numerical procedure, and uses various branches of mathematics. approach is equally useful for the economists, administrators, planners, irrigation or agricultural experts and statisticians etc. The validity of the solution is checked by comparing the results with those ob­tained without using the model. (vii) It is the application of the scientific methods by scientists and subject specialists to the study of the given operation. The broad, interdisciplinary nature of operations research makes it a field with extensive variety – it is utilised in many industries, with many opportunities arising continuously for new applications. In India, operations research came into existence with the opening of an OR unit in 1949 at the Regional Research Laboratory in Hyderabad.
