Chen Hua-yan · Ordnance Industry Automation · 2006
Research of IBMS OAS based on Petri net workflow, taking document circulation as example, the event sequence in circulation example was found out at first. When workflow was executing, one token in C1 was used to trigger and carry out task 1; after that, the token was consumed and sent to the other C1; then, a new token was generated by C1. The task 2 was triggered by the new C1 token; then, the new token was sent to C2 and C3. Task 3 and task 4 could be triggered at the same time or asynchronously. After executing trigger, the token was sent to C4 and C5, and one token was generated by each of then to trigger task 5 and sent to C6 at last. The workflow was completed.
