Information
This model describes the retail of produced goods. Goods that are being sold 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.
The retail model is the same model as the distribution model except for the parameter values used.
