Explicação para professores e alunos sobre IO
In a nutshell, operational research (O.R.) is the discipline of applying advanced analytical methods to help make better decisions.
By using techniques such as problem structuring methods (sometimes known as ‘Soft O.R.’) and mathematical modelling to analyse complex situations, operational research gives executives the power to make more effective decisions and build more productive systems based on:
- More complete data
- Consideration of all available options
- Careful predictions of outcomes and estimates of risk
- The latest decision tools and techniques

Analysis of Risky Decisions
Making decisions is certainly the most important task of a manager and it is often a very difficult one. This site offers a decision making procedure for solving complex problems step by step.It presents the decision-analysis process for both public and private decision-making, using different decision criteria, different types of information, and information of varying quality. It describes the elements in the analysis of decision alternatives and choices, as well as the goals and objectives that guide decision-making. The key issues related to a decision-maker’s preferences regarding alternatives, criteria for choice, and choice modes, together with the risk assessment tools are also presented.

Posted by Armando Brito Mendes | Filed under Investigação Operacional
Operations research (also referred to as decision science, or management science) is an interdisciplinary mathematical science that focuses on the effective use of technology by organizations. In contrast, many other science & engineering disciplines focus on technology giving secondary considerations to its use.
A Investigação Operacional (IO) ou Pesquisa operacional (PO), é um ramo interdisciplinar da matemática aplicada que faz uso de modelos matemáticos, estatísticos e de algoritmos na ajuda à tomada de decisões. É usada sobretudo para analisar sistemas complexos do mundo real, tipicamente com o objectivo de melhorar ou optimizar a performance.
