The Production page displays summary information on the utilization of production facility nodes (typically plants or factories).
The bar chart Open Location Capacity versus Utilization shows the actual utilization versus the capacity for each production facility. This gives you an idea of which production facilities are being under-utilized, which may benefit from expansion, and so on.
The table Production Usage shows details about capacities of production facilities (supported by the visualization in the bar chart below it). To find out what would happen to the network if certain production facilities are forced open or closed, you can make selections in the checkboxes and click Optimize (AIMMS icon) to solve again.
