Operations Research (OR) emerged as a discipline during World War II, driven by the need to optimize military operations. Scientists and engineers from various fields collaborated to develop techniques for resource allocation, logistics, and strategic planning. The success of these efforts led to the adoption of OR in the business world after the war.

• Early Developments:

  • Linear programming was developed by George Dantzig in 1947.
  • Queueing theory was developed by A.K. Erlang in the early 20th century.
  • Simulation techniques were developed by John von Neumann and Stanislaw Ulam.

• Post-War Growth:

  • OR techniques were applied to a wide range of business problems, including inventory management, production planning, and marketing.
  • The Operations Research Society of America (ORSA) was founded in 1952.
  • The Institute for Management Sciences (TIMS) was founded in 1953.

• Modern Era:

  • Advances in computing technology have enabled the development of more sophisticated OR models and algorithms.
  • OR is now used in a wide range of industries, including manufacturing, logistics, finance, healthcare, and government.
  • The rise of data science and machine learning has further expanded the scope of OR.

Impact on India:

• OR has played a significant role in improving the efficiency and productivity of Indian industries.
  • Indian universities and research institutions have made significant contributions to the field of OR.
  • OR professionals are in high demand in India, particularly in the IT, manufacturing, and logistics sectors.

From its origins in military strategy to its current applications in diverse industries, Operations Research continues to evolve as a powerful tool for decision-making and problem-solving.
