Draw an activity diagram using signals to capture the following series of events:

  1. Three days before the flight, my travel agent emails me with a list of required travel documents.
  2. If the list is not received by the three day deadline I cancel the flight.
  3. Otherwise: Three hours before the flight, I order a taxi. When the taxi arrives, I depart for the airport

Hi I'm wondering can any one help me with this I have an exam coming up and am having trouble, especially with timed events. Thank you.

The timing is planned in Timing diagrams, maybe a bit in State machine or Sequence diagrams, but Activity diagram is inconvenient for it. And definitely your examples are not so non-standard.

Use Timing diagram!

Look for an example here, search for "timing" on the page
