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.
