The Operations Research techniques are not simple but involve higher mathematics. The tendency today is to combine several of these techniques and form more sophisticated and advanced programming models. The subject of operation research was born during Second World War in U.K., and was used for military strategy. During World War II, a group of scientists, having representatives from mathematics, statistics, physical and social sciences were entrusted to the study of various military operations. This team was very success­ful and greatly contributed to the meticulous handling of entire operation and related problems of the operation. After the World War II, it was started applying in the fields of industry, trade, agriculture, planning and various other fields of economy. The present study accounts the applications of Operations Research to prove the multidisciplinary of O.R.
