Considerations Regarding the Valence and Diversity of Operations Research Models

Operations research(OR), also called decision optimization science, is the one that provides mathematical models meant to lead to finding the optimal variant in an economic, military, social, political, etc. type of activity. These are methods with a major potential, highlighted since the emergence of the models used in World War II actions and later in various other fields, especially in western countries. This paper aims to highlight the benefits of using OR techniques over time and especially to highlight its applicability. In this paper we summarize the presentation of the evolution and contributions of Operational Research in various fields until the ‘60s, a future paper will deal with the time frame 1960-2020.
