Operations research, operational research, or simply OR is an interdisciplinary science which deploys scientific methods like mathematical modeling, statistics, and algorithms to decision making in complex real world problems which are concerned with coordination and execution of the operations within an organization. The nature of organization is essentially immaterial. The eventual intention behind using this science is to elicit a best possible solution to a problem scientifically, which improve or optimize the performance of the organization.

Operations research in context


The terms operations research and management science are often used synonymously. When a distinction is drawn, management science generally implies a closer relationship to the problems of business management.

Uncertainty in Industrial Practice: A Guide to Quantitative Uncertainty Management
Etienne de Rocquigny (Editor), Dr. Nicolas Devictor (Editor), Dr. Stefano Tarantola (Editor) Mon, 30 Jun 2008 04:00:00 -0000
  There is a growing demand from institutional bodies for the justification of industrial methodologies and practices (e.g. safety criteria, environmental protection and control, maintenance and design optimization). Previous books in this area have either been too theoretical, or too specific in their scope. Uncertainty in Industrial Practice aims to provide a practical reference on uncertainty treatment for all types of industry, Read More...

Bayesian Approach to Inverse Problems
Jérôme Idier (Editor) Mon, 30 Jun 2008 04:00:00 -0000
  Many scientific, medical or engineering problems raise the issue of recovering some physical quantities from indirect measurements; for instance, detecting or quantifying flaws or cracks within a material from acoustic or electromagnetic measurements at its surface is an essential problem of non-destructive evaluation. The concept of inverse problems precisely originates from the idea of inverting the laws of physics to recover a quantity of interest Read More...
Time Series Analysis: Forecasting and Control, 4th Edition
George E. P. Box, Gwilym M. Jenkins, Gregory C. Reinsel Mon, 30 Jun 2008 04:00:00 -0000
  This is a revision of a classic, seminal, and authoritative book that has been the model for most books on the topic written since 1970. It focuses on practical techniques throughout, rather than a rigorous mathematical treatment of the subject. It explores the building of stochastic (statistical) models for time series and their use in important areas of application forecasting, model specification, Read More...
