Webb25 juli 2016 · In standard form, linear programming problems assume the variables x are non-negative. Since the variables don’t have standard bounds where 0 <= x <= inf, the bounds of the variables must be explicitly set. There are two upper-bound constraints, which can be expressed as. dot (A_ub, x) <= b_ub. Webb1. The following linear programming model is solved by simplex method in the tableau format. (1) What are basic variables in first and second constraints, respectively? (2) What are the marginal values for two constraints? (3) What is B − 1? Max Z = 3 X 1 + 2 X 2 S.T. X 1 + X 2 ≤ 4 Z 2 X 1 + X 2 ≤ 6 X 1, X 2 ≥ 0 2. Continued!
