At the end of the optimization, the final solution can be displayed by clicking on the Detailed results button. If the check box Display Dual is selected, the shadow prices associated to the constraints are also displayed.
The data concerning the family items are displayed first (Sales, Sub-contracting, Production, Inventory). Then the data concerning the resource items are displayed (capacity coefficients, capacity increase, capacity decrease, overcapacity).
The interest and use of the dual variables (and associated shadow prices) is a standard issue of a linear programming course.
