The operational research was born during the years of the World War II out of the need to use scientific methods in the organization of the logistics of the military operations. After the war, the methods of the operational research proved to be extremely efficient in the social-economical decision-making. In the present paper, we present the main chapters of the operational research: Transportation issues, Linear Programming, the Analysis of the Critical Path, the Theory of Wait, the Theory of Supplies, the Theory of the Strategy Games, the Theory of the Decision, Multicriteria Structures. The paper presents as well, the relationship with the connected fields of the operational research: Informatics, the Systems Analysis, and Cybernetics. In the final part of the paper, we show the importance of the operational research in the rational decision-making.
