The Operational Research Society (OR Society), also known as The OR Society, is an international learned society in the field of operational research.The OR Society is a leading professional body for operational research (OR) practitioners and academics. Based in the United Kingdom, the society promotes the understanding and use of operational research in addressing real-world problems across various sectors, including industry, government, and academia.
Its mission is to advance the science and practice of operational research by encouraging innovation, promoting knowledge sharing, and offering support for OR professionals. The Society has 4,000+ members (2024) and continues to grow year on year, the headquarters are in Birmingham, England.
History
The OR Society was established in 1948 as the world’s first operational research society, reflecting the growing interest in the use of scientific methods to solve complex management and operational problems. The roots of OR date back to World War II, where techniques such as simulation, optimisation, and statistics were used to enhance military operations. After the war, these methods began to be applied to a wide range of industries and organisations, leading to the formation of a dedicated society to support professionals in this emerging field.
The OR Society was founded by pioneers in the field, including notable figures such as Sir Charles Goodeve and Patrick Blackett. The society's first meeting was held in the London School of Economics, and its founding goal was to develop and disseminate OR techniques while providing a platform for networking and collaboration. Since then, the society has grown to include thousands of members globally and continues to be a significant force in the evolution of operational research, with members in 53 countries. A full history of The OR Society can be found at https://www.theorsociety.com/ORSHistory
The OR Society is registered charity number 313713[1] and also a company limited by guarantee (Company number 00663819).[2]
Its charitable objectives are:
the advancement of knowledge and interest in OR.
the advancement of education in OR.
The governance of The OR Society is structured around a Council, which serves as the governing body responsible for the strategic direction and overall management of the society. The Council comprises elected members, including the President, Vice-President, Treasurer, and other key officers.
The President of the society typically serves a term of two years, while other council members may serve in various capacities for terms ranging from one to three years. These roles are filled through elections, ensuring that governance remains democratic and representative of the society’s diverse membership. The Council meets regularly to discuss matters related to policy, finance, membership, and the future development of the society.
Several committees support the Council in carrying out its duties. Each committee focuses on specific areas such as financial oversight, scholarly output, and professional development. The management of the society is overseen by a General Council, consisting of up to 36 members. Its affairs are managed by a board, consisting of five officers elected by the membership, including the President, the immediate Past President or the President Elect, two vice presidents, an Honorary Treasurer, and up to six members of the General Council.[3] /</ref> The current president is Sanja Petrovic. Previous presidents have included Sir Owen Wansbrough-Jones, Maurice Kendall, John Giffard, 3rd Earl of Halsbury, George Alfred Barnard, and K. D. Tocher.

Through the Pro Bono OR scheme, volunteer practitioners provide free operational research consultancy services to help non-profits improve efficiency, resource allocation, and decision-making processes. The types of support provided include:
Process optimisation: Helping organizations streamline their operations to reduce waste and improve productivity.
Data analysis and forecasting: Assisting with analysing large datasets to predict future trends, demand, or outcomes.
Strategy development: Supporting the design of long-term strategies based on quantitative analysis and modelling techniques.
Capacity planning: Helping charities assess their staffing and resource needs based on future demand.
This initiative allows OR professionals to apply their skills to social good while gaining valuable experience in diverse settings. It also demonstrates the impact of operational research beyond traditional business and industry applications.
Accreditation
Accreditation is a formal process of evaluating and recognising an organisation, institution, or program as meeting specific standards of quality and competence. OR Society accreditation recognises OR professionals as they progress through grades Candidate Associate, Associate, Associate Fellow and Fellow of the OR Society over the course of their career.
Appropriately experienced ORS members can access Chartered Scientist and Registered Scientist accreditation with the Science Council, and/or Certified / Advanced Data Science Professional via the Alliance for Data Science Professionals
These accreditation routes are not mutually exclusive, meaning many ORS members achieve accreditation in more than one of the pathways.
The OR Society offers its members three pathways for professional certification
OR Society accreditation Chartered Scientist and Registered Scientist Certified / Advanced Data Science Professional
These are offered only to members because membership of a relevant professional society is universally recognised as a key component of certified professional competence..

Learning analytics is the measurement, collection, analysis and reporting of data about learners and their contexts, for purposes of understanding and optimizing learning and the environments in which it occurs. The growth of online learning since the 1990s, particularly in higher education, has contributed to the advancement of Learning Analytics as student data can be captured and made available for analysis. When learners use an LMS, social media, or similar online tools, their clicks, navigation patterns, time on task, social networks, information flow, and concept development through discussions can be tracked. The rapid development of massive open online courses (MOOCs) offers additional data for researchers to evaluate teaching and learning in online environments.
