In class we described the links between BPMN and process modeling.
Let's explore this issue in more detail.
- Consider the BPMN diagram:
and assume that the steps as marked represent time spent locally.
Give a CPM precedence diagram for this case, assuming that only
the middle pool is local/executable.
- Do critical path analysis on the preceding and determine the critical
- Assume that the node "get flights" does not have a constant time,
but rather, that its time is described by an empirical distribution
out of 100 trials. Remembering that expected time is the sum of
Prob(event)*time(event), what is the expected time for the process now?
Suppose that the "get hotels" operation has its own empirical
What is the expected time to completion now? Hint: you must compute
the probability of each time separately, using both tables.
