What is Operations Research?


Many people probably never heard the phrase “Operations Research” used. Operations Research (OR), or operational research in the U.K, is a discipline that deals with the application of advanced analytical methods to help make better decisions. The terms management science and analytics are sometimes used as synonyms for operations research. Yet, in my experience OR extends far beyond either. The figure shows a hierarchy of operations research activities, and I’ll let you decide if they are also performed in analytics.

  • Data Mining and Machine Learning
  • Artificial Intelligence and Expert Systems
  • Financial Engineering
  • Games, Decision, and Strategic Planning
  • Marketing Research
  • Investment Science
  • Experimental and Engineering Design
  • Manufacturing and Production
  • Logistics and Transportation
  • Supply Chain Management
  • Enterprise Resource Planning

Modeling Systems and Optimization Services is an interface part that bridges OR modeling with OR tools. When implemented smoothly, it is the part that is not noticed by modelers or users.

Where do you find them?

Operation Research Analysts work in many industries, including maritime, space operations, defense, airlines, train lines, financial service, entertainment and many more. Wherever operation occur, operations research analysts are usually there. The following lists several key functional areas for operations research analysts.

  • Communications
  • Interfaces
  • Networks
  • Scheduling
  • Routing
  • Manpower
  • Modeling

What are Their tools?

Underlying Tools is the level that is typically regarded as what uniquely defines Operations Research.

  • Mathematical Programming
  • Computing Technology
  • Probability and Statistics
  • Stochastic Simulation
  • Systems Analysis
  • Organization Theory
  • Accounting Principles
  • Engineering Economics
  • Decision Analysis
  • Game Theory
  • Heuristics
  • Computer Programming
  • Numeric Methods
  • Stochastic Analysis
  • Queuing Theory
  • Evolutionary Algorithms
  • Dynamic Programming

What are they built upon?

Foundations upon which OR are built include:

  • Mathematical Theory
  • Statistical Theory
  • Computing Theory
  • Economic Theory

What is their history?

Operational Research was born during the early year of WWII and matured rapidly. One of its primary function was the planning of Operation Overlord or the Normandy Invasion. It has its foundations in mathematics, computing and economic theories, on which basic tools in optimization and simulation are built.  Today OR’s are employed by airlines, train lines, logistic systems, delivery systems (e.g., FedEx), defense systems, military, oil companies, insurance companies, financial institutions, manufacturing, marketing and many more.
