Quizplus · Accepted Answer

Decision variables are unknown values that the model seeks to determine. They represent the quantities that the model seeks to optimize or minimize. Restrictions or limitations are represented by constraints in the model. Quantities for which no feasible solutions exist would not be considered decision variables in the optimization model.
