YAWL and OR-joins (2)
Consider the following extract from a YAWL model:
a) Describe the execution semantics of the OR-join. What is the fundamental difference to other joins such as XOR-join, AND-join, discriminator and m-out-of-n-join?
b) Which execution order of the activities are allowed for the model given above (i.e. which traces are allowed)?
More information on YAWL can be found in the book in chapter 4.5.
