ABSTRACT
Operations Research (OR) is one such science that provides better solutions to the managers, engineers and any practitioners with better solutions. This science came into existence during World War II. Though it was first employed for military operations, its applications are extended to any field on the earth in some form or other. The name operations research was given to this subject because it has started with the research of operations. During world war - II, the military commands of UK and USA engaged several teams of scientists to discover tactical and strategic military operations. About four to five decades ago it would have been difficult to get a single operations researcher to describe a procedure for conducting OR project. But today, every engineer and manager are presenting the procedure in different ways as suits to their situations. Operations Research model provides a clear and distinct direction to the managers in decision making and problem solving.
