About The OR Society

The Operational Research Society is the UK’s professional home for operational research, decision analytics and data science. Our mission is to improve real-world decisions through the use of data, analysis and structured thinking. Founded in 1948, we support members through professional accreditation, training, journals, conferences and a global community.

Operational Research Society (ORS)  grew during World War II when scientists and military experts used analysis to improve military decisions and efficiency. This pioneering work showed how structured thinking could solve complex problems.   

Formation and the Early Years

Founded in 1948, the Operational Research Society was formed to support the use of these methods in industry, government, and academia. Since then, the Society has helped develop the practice of operational research and continues to connect people who use data and analysis to improve decisions.

Growth and Development

During the 1950s and 1960s the Operational Research Society grew in size and influence. The Society hosted conferences and seminars to share knowledge and support collaboration, while the Journal of the Operational Research Society became a key outlet for research in the field.

Influence and Impact

By the 1970s the Operational Research Society had become a recognised voice in the global OR community. It supported the use of OR methods across sectors such as manufacturing, transport, healthcare and finance, while also promoting OR education in universities and helping train future professionals.

Modern Era

In recent decades, the Operational Research Society has adapted to new technology and methods. Digital platforms have expanded access to resources, events and networks. The Society continues to promote best practice and support the development of operational research.

Achievements and Recognition

The Operational Research Society has reached many milestones, including awards such as the Beale Medal and the President’s Medal that recognise leadership in the field. Members have led work that improves decisions across sectors, strengthening the Society’s global influence in both research and practice.

A global movement

By 1955 interest in operational research had spread across many Western countries. Membership of the Society grew from fifty founding members to around 1,250 by 1964. Today the Society has 4,500+ members, including academics, practitioners and students who benefit from training, publications and networks.

Our 'Draw My Life' animation about Lord Patrick Blackett, a true pioneer of Operational Research, further brings this history to life and celebrates his key role in ORS history. 

Defining the Field

In 1941 Professor Patrick Blackett described operational research as scientists working with operational teams to analyse real data and improve decisions. In 1947 Charles Kittel defined it as a scientific method that gives executives a quantitative basis for decision making, while Sir Charles Goodeve later called it “quantitative common sense”.

By 1962 the field was described as the use of modern science to address complex management problems involving people, systems and resources. Today the Operational Research Society focuses less on strict definitions and instead shows the value of OR through real examples and practical impact.

Looking Forward

The Operational Research Society continues to support the growth of operational research by building a strong community and encouraging collaboration across sectors. Its work helps advance the use of OR to address modern challenges.

Inside OR is the society's quarterly magazine, featuring news, methods, people and events, from across the field.  The Journal of the Operational Research Society s an international journal that publishes research and practical applications in operational research.
