For example the constraint -X1 + X2 ≤ -3 is equivalent to the equation -X1 + X2 + S1 = -3,S1 ≥ 0 Now multiplying both sides by -1 will render a non-negative right-hand side as desired that is X1 - X2 - s1 =3 Posted by … Webb20 okt. 2016 · Now let’s go back to the statement: “The reduced cost of a decision variable (i.e. value 3 for variable x1) is equal to the shadow price of the non-negativity constraint of the variable (i.e. x1 >= 0)”. The shadow price for the constraint x1 >= 0 can be defined as follows: If you increase the right hand side of that constraint (currently ...

Webb• What will happen to the objective function if the right side of the constraints increase by 1? • You must find the shadow prices for BINDING CONSTRAINTS. • NON-BINDING CONSTRAINTS always have a shadow price of 0.
