Information

This model describes the distribution network of produced goods. Goods that are being distributed are represented by the mass-flow model in the lower part of the graph, whereas the orders for these goods are represented by the mass-flow models in the upper part of the graph. The signal-flow model represents the control of the flow of goods based on the information obtained from their order status.
