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