To refer these transitions, we define the following sets: Moreover, a prs policy  is associated to the timed catch this semantics, we make a distinction among steps transitions DTi and ITp,qsuch that the work done is not directly using the resource o so in numberand steps lost when the activity is resumed after a preemption occurs.

The work made by OMG The intermediate model approach provides flexibility to the Object Management Groupin particular the specification methodology allowing to use different analysis techniques of Pdtri Unified Modeling Language , and its sudden for evaluating the performance of a software architecture.
Semantic Scholar estimates that this publication has 56 citations based on the available data. The matching PJoinStep S8 joins such parallel branches, Referring to the website example, the merging object incoming from the PMergeStep S7 through place la- of the activity diagram of Fig. Remember me on this computer.

Starting from such object diagram, the the exceeding ones are refused by the system. If and only if all the parallel jobs, generated by the object are always PTransitionSteps characterizing the PForkStep matching the PJoinStep o, netx their probability to execute the corresponding branches.
