These models provide the ‘best’ or ‘optimal’ solution to problems subject to certain limitations of the use of resources.

During world war II, military management called on scientists from various disciplines and organized them into teams to assist in solving strategic and tactical problems (ie) to discuss, evolve and suggest ways and means to improve the execution of various military projects. This new science came into existence in military context. The term operations Research was first coined in 1940 by McClosky and Trefthen in a small town, Bowdsey, of the United Kingdom.
