NettetConstraint 1: Since x1 < 6 is not a binding constraint, its dual price is 0. Constraint 2: Change the RHS value of the second constraint to 20 and resolve for the optimal point determined by the last two constraints: 2x1 + 3x2 = 20 and x1 + x2 = 8. The solution is x1 = 4, x2 = 4, z = 48. Hence, the dual price = znew-zold = 48 - 46 = 2.

NettetIn some cases, another form of linear program is used. A linear program is in canonical form if it is of the form: Max z= cTx subject to: Ax b x 0: A linear program in canonical form can be replaced by a linear program in standard form by just replacing Ax bby Ax+ Is= b, s 0 where sis a vector of slack variables and Iis the m m identity matrix. Nettet6.10 D. Is binding: The effect of deleting a linear constraint from a linear programming model depends on whether or not that constraint is binding. A binding constraint is one that must be satisfied in order for the model to be feasible. If the constraint is binding, then deleting it will make the model infeasible.
