Diet Problem: Students’ Nutrition at the University of Split

A diet problem is one of the oldest optimization problems. The goal is to select a set of food to satisfy meal nutritional requirements at minimum cost. In this paper the diet problem is used to optimize students’ nutrition at University of Split. The criterion was the minimum energy amount of the meal. After data have been collected and statistical analysis performed, decision variables as well as an appropriate mathematical model are defined. According to prescribed food and nutritional requirements, a range of constraint inequalities has been set up. The problem is solved by means of MS Excel Solver. Sensitivity analysis both on objective coefficients and constraints RH sides is carried out. An optimal solution is proposed.
