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, 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 overlap 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 complex decision-making problems. The term management science is sometimes used as a synonym. It is sometimes considered to be a subfield of mathematical sciences. Operations research ( British English: operational research), often shortened to the initialism OR, is a discipline that deals with the development and application of advanced analytical methods to improve decision-making.

It is highly interdisciplinary, borrowing questions from philosophy, methods from neuroscience and insights from clinical practice - all in the goal of furthering our grasp of human nature and society, as well as our ability to develop new intervention methods.įrontiers in Psychology, as a large, multidisciplinary and open-access journal, aims to be at the forefront of disseminating the best scientific knowledge and impactful discoveries to researchers, academics, clinicians and the public worldwide.įrontiers in Psychology is a member of the Committee on Publication Ethics.The examples and perspective in this article may not represent a worldwide view of the subject. Today, psychological science is becoming increasingly important at all levels of society, from the treatment of clinical disorders to our basic understanding of how the mind works. Frontiers in Psychology is the largest journal in its field, publishing rigorously peer-reviewed research across the psychological sciences, from clinical research to cognitive science, from perception to consciousness, from imaging studies to human factors, and from animal cognition to social psychology.įield Chief Editor Axel Cleeremans, at the Université libre de Bruxelles, is supported by an outstanding Editorial Board of international researchers.
