Data Analysis and Decision Modeling

18. How are binary variables specified in the Analytic Solver Platform (ASPY? a. By replacing RHS values in constraints with 0 or 1. b. By specifying changing cells as INTEGER and as non-negative. c. By specifying changing cells as BINARY in the Variable Type/Bound area of ASP. d. By selecting Assume Binary Model in the ASP Options dialog box. 19. An ILP problem has 5 binary decision variables. How many possible integer solutions are there to this problem? a. 5 b. 10 c. 25 d. 32 20. Consider the constraint X3 + X4 +X5 + X6 + X7 > 27 representing Air Express' Monday minimum worker requirement. Why was a ">" used versus an "="? a. The ">" is needed to accommodate workers held over from Sunday. b. Solver only accepts ">" constraints. c. The ">" is less restrictive. d. The "=" will always produce an infeasible constraint
