Non-linear process plans are process plans which comprise different manufacturing alternatives Such non-linear process plans increase the flexibility of scheduling activities and allow to remedy quickly to disturbances in the workshop They are represented by Petn nets
The automatic generation of a non-linear process plan is realised m different steps:
- the feature based workpiece description is transformed into a non-linear sequence of operation steps:
- the resources capable to manufacture : he specified operation steps, are determined.
- the non-linear sequence is converted into a non-linear process plan which is directly usable for scheduling
