 -Example: P, Q and R Production System

To illustrate, consider the production process producing three products P, Q and R. The process is described in the figure below.
Each rectangle describes an operation in the production process. The number in the center of each box is a unique identifier for the part produced by the operation. Each circle indicates a raw material input. The unit price and raw material designation is shown in the circle. The rectangles with the rounded corners name the finished goods P, Q and R which correspond to parts 400, 450 and 250 respectively.

The arrows passing between operations and raw materials show the flow of materials between operations and from raw materials to operations. The small numbers next to the arrows show the number of units of material necessary for the receiving operation.
