Because of the computational and statistical nature of most of these fields, OR also has strong ties to computer science and analytics. Nearly all of these techniques involve the construction of mathematical models that attempt to describe the system. Operational research (OR) encompasses the development and the use of a wide range of problem-solving techniques and methods applied in the pursuit of improved decision-making and efficiency, such as simulation, mathematical optimization, queueing theory and other stochastic-process models, Markov decision processes, econometric methods, data envelopment analysis, ordinal priority approach, neural networks, expert systems, decision analysis, and the analytic hierarchy process. Originating in military efforts before World War II, its techniques have grown to concern problems in a variety of industries.
Operations research is often concerned with determining the extreme values of some real-world objective: the maximum (of profit, performance, or yield) or minimum (of loss, risk, or cost). Because of its emphasis on practical applications, operations research has overlapped with many other disciplines, notably industrial engineering.
Įmploying techniques from other mathematical sciences, such as modeling, statistics, and optimization, operations research arrives at optimal or near-optimal solutions to decision-making problems. The term management science is occasionally used as a synonym. Air Force Specialty Code: Operations Analysis), often shortened to the initialism OR, is a discipline that deals with the development and application of analytical methods to improve decision-making.
