The range of optimality is useful only for basic variables. a. True b. False ANSWER: False POINTS: 1 DIFFICULTY: Easy LEARNING OBJECTIVES: IMS.ASWC.19.18.01 - 18.1 NATIONAL STANDARDS: United States - BUSPROG: Reflective Thinking TOPICS: 18.1 Sensitivity Analysis with the Simplex Tableau KEYWORDS: Bloom's: Remember 2. The range of optimality is calculated by considering changes in the cj − zj value of the variable in question. a. True b.

As long as the objective function coefficient remains within the range of optimality, the variable values will not change although the value of the objective function could. a. True b.

If the simplex tableau is from a maximization converted from a minimization, the signs and directions of the inequalities that give the objective function ranges will need to be adjusted to apply to the original coefficients. a.
