7
 
 
8
 
Booking takes at least 3 minutes but if it takes more than 5 minutes, the booking server will terminate the connection and the whole booking process has to be restarted by firing the transition restart1.
9
 
 
10
 
After booking the payment has to be done within 10 minutes since the session (including booking) was initiated, otherwise the connection will close and the whole process restarts by firing restart2. The transport arcs allow us to measure the total time since the session started.
11
 
 
12
 
Each time the booking is restarted, one attempt is used (the place attempts initially gets 3 tokens as the output arc from the transition start is weighted).
13
 
 
14
 
After successful payment or after all three attempts were used, the workflow has to terminate. In case of success, using the urgent transition empty, we will without any delay empty the place attempts and immedialy finish the workflow by firing the transition success.
15
 
 
16
 
The two queries together guarantee strong soundness of the workflow net. Alternatively, open in the menu Tool/Workflow analysis and verify soundness of the workflow while computing shortest and longest duration of the workflow.</labels>
