The purpose of Operations Research is to prepare the professional to decide between different means or methods available to achieve a proposed objective, so that a result is achieved in relation to certain optimization criteria.
Although intuition and experience are part of the considerations in a decision-making process, some decisions deserve a more in-depth study, due to their consequences and the complexity of the context, making a methodological support essential for making decisions. decisions, which can be found in the procedures of the operations investigation system operations engineer.
It could be seen that one of the earliest historical examples of the use of operational research is the mission entrusted to Archimedes by Hieron, tyrant of Syracuse, to apply the best means and methods to defend the city against the attacks and siege of the Romans.
But operational research has only benefited from systematic application until the Second World War, mainly in the conduct of large military operations. Operational research uses computers to a large extent; the invention and commercialization of these machines were the primary condition of their development in the civil domain and especially in the business economy. By happy coincidence, it is only in our time that the management problems of large companies have become hopelessly complex.. Although it is essential for the operational research technician to study the general problems that arise and the classical algorithms that allow them to solve them, he must also be fully convinced that the practical situations that he will encounter will be much more complicated and that he will have to undertake a Original task to satisfy the decision maker by offering him the possibility to optimize according to his own criteria.
