Operations research analyzes and presents scientific procedures for decision making in engineering, technology management and management human, productive and financial resources of an organization.
The main purpose of Operations Research is to optimize the system performance when subjected to restrictions.
It is based on mathematical modeling and uses optimization techniques (convex) and graph theory.
The main calculation algorithm is the SIMPLEX table and network, considered one of the two most important algorithms of the twentieth century (https://www.siam.org/pdf/news/637.pdf).
Operations research was meant to optimize the use of scarce resources during the 2nd world war and, having gained dominance in the industry and management. It is presented today as one of the main tools of business decision making (scientific and non-empirically). In addressing this matter, the main priority is the”basic principles”and detailed examples at the expense of theoretical complexity that this subject today presents.
O.R. can be used in optimal radiation therapy, finding the shortest path in a network, settingprices in the stock exchange market, etc.
