Abstract: Methods, apparatuses, and systems are presented to simplify optimization problems in order to reflect the decision strategies of a person or persons (decision makers) while taking advantage of the structure of the underlying mathematical model given by the classification of variables and functions according to their real meaning in the context of the problem. This allows the generation of solutions whose behavior better reflects the necessities of the decision maker in a faster and easier way. At the same time, the generated optimization problems are simplified, making them much easier to construct and solve numerically.
