Figure 8.
A horizontal process diagram is divided into two sections labelled supplier and manufacturer. On the left, an external demand function connects to a demand rate symbol that leads to a box labelled orders. From the orders box, an arrow labelled request rate leads to a stacked block listing supplier 1, supplier 2, and supplier n. From the supplier block, an arrow labelled supply rate leads to a box labelled warehouse. Curved arrows connect orders with request rate and suppliers with supply rate. From the warehouse box, an arrow labelled manufacturing rate leads to a box labelled output. From the output box, an arrow labelled shipping rate extends to the right toward an external symbol. Curved feedback arrows connect warehouse with manufacturing rate and output with shipping rate. A curved arrow also connects the supplier section to the warehouse area across the top of the diagram.Stock and flow model of the underlying supply chain
