Grades

The Grades page shows the grades available in the case, together with the material types and traded materials to which the grades belong. Grades are added automatically when plant models are associated with the model, or can be entered manually.

The Grades page shows only the products that are available in the network. Actual flows of grades at each demand must be defined in the Demands page in terms of their price and requirement. Grades can only be associated with demand nodes, so if a sale of product is required at a location, a demand node must be present here. For example, you cannot sell directly from a plant or terminal, but a demand node must be created and the grade transferred from the plant to the demand via a transport link.
