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

The Project Management Hut
Posted by Armando Brito Mendes | Filed under Investigação Operacional, planeamento
Excelente site sobre tudo o que se relaciona com gestão de projetos
PM Hut – The Project Management Hut, came to life when a group of Project Managers decided to make their vast experience accessible to everyone. Needless to say, they started writing articles and gathering articles from all over the world, categorizing these articles, and presenting them in a very digestible format for the dynamic Project Manager.
Today, PM Hut is considered to be the largest database of categorized Project Management articles on planet Earth. Apparently, a group of Project Managers working together were able to finish something; it seems that reading the “Conflict Management” articles on PM Hut managed to resolve our own conflicts!
