History of Operations Research:

Operations Research (OR) has its roots in the early 20th century and evolved as a response to the complex challenges posed by World War II. The discipline emerged from the efforts of military planners to optimize resource allocation and strategic decision-making.

World War II Origins:

• During World War II, military operations faced intricate logistical and tactical problems.


• Mathematicians and scientists were brought together to apply quantitative methods to military planning.


• Notable figures like George Dantzig and A.P. Rowe made significant contributions.

Formation of OR Societies:

• After the war, interest in applying mathematical methods to problem-solving persisted.


• The Operational Research Society (ORS) in the UK, established in 1948, played a pivotal role in formalizing the field.


• The U.S. Operations Research Society (now INFORMS) was founded in 1952.

Post-War Industrial Applications:

• OR methodologies found applications beyond the military, extending to industries.


• Businesses began using mathematical modeling to optimize production, inventory, and distribution processes.

Development of Key Techniques:

• Linear programming, developed by George Dantzig in the late 1940s, became a cornerstone of OR.


• Simulation techniques, game theory, and network analysis also gained prominence in the 1950s and 1960s.

Expansion into Various Fields:

• OR expanded into diverse fields such as healthcare, transportation, finance, and telecommunications during the latter half of the 20th century.


• Increasing computational capabilities further fueled the growth of the discipline.

Integration of Computers:

• The advent of computers in the 1960s and 1970s revolutionized OR, allowing for more complex modeling and efficient solution algorithms.

Global Spread:

• OR became a global discipline, with societies and associations established in various countries.


• Educational programs and research centers dedicated to OR proliferated worldwide.

Continuous Evolution:

• OR continues to evolve, incorporating advanced mathematical techniques, artificial intelligence, and data analytics.


• Its applications in supply chain management, optimization, and decision analysis remain vital in addressing contemporary challenges.

The history of Operations Research reflects its dynamic evolution from a wartime necessity to a versatile discipline applied across industries for systematic problem-solving and decision optimization.
