Factory model
Diagram of Factory

Information

This model describes the factory floor. Goods under production are represented by the mass-flow model in the lower part of the graph, whereas incoming orders for these goods are represented by the mass-flow model in the upper-right part of the graph. The signal-flow model represents the control of the production of new items based on the information obtained from the incoming orders.
