OPERATIONS RESEARCH: HISTORY 
? The roots of OR can be traced back many 
decades, when early attempts were made to 
use a scientific approach in the management 
of organizations.  
? However, the beginning of the activity called 
operations research has generally been 
attributed to the military services early in World 
War II.  
? Because of the war effort, there was an urgent 
need to allocate scarce resources to the 
various military operations and to the activities 
within each operation in an effective manner.

? Because of the war effort, there was an urgent 
need to allocate scarce resources to the 
various military operations and to the activities 
within each operation in an effective manner.  
? Therefore, the British and then the U.S. military 
management called upon a large number of 
scientists to apply a scientific approach to 
dealing with this and other strategic and tactical 
problems.  
? In effect, they were asked to do research on 
(military) operations. These teams of scientists 
were the first OR teams.  
? By developing effective methods of using the 
new tool of radar, these teams were instrumental 
in winning the Air Battle of Britain.

? Through their research on how to better manage convoy 
and antisubmarine operations, they also played a major 
role in winning the Battle of the North Atlantic. 
? Similar efforts assisted the Island Campaign in the 
Pacific. 
? A key person in the post-war development of OR was 
George B Dantzig. In 1947, he developed linear 
programming and its solution method known as simplex 
method.  
? Besides linear programming, many other tools of OR 
such as statistical control, dynamic programming 
queuing theory and inventory theory were well 
developed before the end of the 1950s.
