The graphs following each table show the sequence
of operations in the Operations Routing Summary and the Process
Plans.
Each node represents an operation identified by its number. All the operations that must be done but whose order may change are connected with an AND junction, whereas operations that must follow a strict sequence appear in that order in a single branch of the graphs. The schemas show which operations correspond to the each node in the process plans. |
