Unit-I Introduction - The term operations research was first coined in 1940 by McClosky and Trefthen in a small town Bowdsey, of the United Kingdom. This new science came into existence in a military context. 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, relating to air and land defense of the country. Their mission was to formulate specific proposals and plans for aiding the Military commands to arrive at decisions on optimal utilization of scarce military resources and efforts and also to implement the decisions effectively. This new approach to the systematic and scientific study of the operations of the system was called Operations Research or operational research.

UNIT – II TRANSPORTATION PROBLEM - The Transportation problem is one of the sub classes of L.P.Ps in which the objective is to transport various quantities of a single homogeneous commodity, that are initially stored at various origins to different destinations in such a way that the total transport cost is minimum. To Achieve this objective we must know the amount and location of available supplies and the quantities demanded, In addition , we must know that costs that result from transporting one unit of commodity from various origins to various destinations.
