History of Operations Research
The history of operations research dates back to World War II, when scientists and mathematicians were recruited to solve complex military problems. Since then, operations research has evolved into a multidisciplinary field that applies mathematical and scientific methods to optimize complex systems and decision-making processes. Today, operations research plays a critical role in various industries, from healthcare to transportation to finance.
The Emergence of Operations Research During World War II
Operations research (OR) is a discipline that applies advanced analytical methods to help make better decisions. While its roots go back to the early 20th century, it truly emerged and took shape during World War II.
In the early days of the war, the Allied forces faced many complex challenges, such as optimizing the use of radar systems, improving the efficiency of anti-aircraft guns, and determining the best way to drop bombs from airplanes.

Military leaders recognized that solving these issues required a scientific approach utilizing a wide range of quantitative techniques.
The field of OR was born out of the need to solve these complex problems and make better decisions that could help win the war.
After the war, the field of OR expanded to other areas, including manufacturing, transportation, healthcare, and finance. OR techniques were used to optimize production processes, improve transportation logistics, and develop better healthcare delivery systems. The field also started to incorporate more advanced mathematical and statistical models that could handle larger and more complex problems.

The Post-War Growth of OR
The birth of OR as a formal field of study can be traced back to the work of British mathematician and physicist Patrick Blackett, who was awarded the Nobel Prize in Economics in 1974 for his contributions to the field. Blackett was instrumental in developing the use of operational research techniques during World War II, and his work helped to transform the field into a formal discipline.
Throughout the latter 20th century, OR grew in both depth and breadth. Specialized subfields emerged within operations research; each focused on developing advanced methodologies to solve particular types of complex problems. Some key subfields include:
- Linear and nonlinear programming
- Queueing theory
- Decision analysis
- Game theory
- Simulation modeling
- Inventory and supply chain optimization
At the same time, constant advances in computing power, data gathering, and algorithmic sophistication enabled operational researchers to tackle larger and more complex problems than ever before across the public and private sectors.
Today, operations research continues to expand its real-world impact, influencing areas as diverse as healthcare, urban planning, environmental protection, and more. By employing a scientific approach to operational decision-making, OR remains an essential tool for organizations seeking optimal results with limited resources.
