This booklet presents the main whole formal specification of the semantics of the enterprise approach version and Notation 2.0 typical (BPMN) to be had thus far, in a method that's simply comprehensible for quite a lot of readers – not just for specialists in formal equipment, yet e.g. additionally for builders of modeling instruments, software program architects, or graduate scholars focusing on company approach management.

BPMN – issued via the item administration workforce – is a everyday average for enterprise approach modeling. besides the fact that, significant drawbacks of BPMN comprise its constrained help for organizational modeling, its in basic terms implicit expression of modalities, and its loss of built-in consumer interplay and information modeling. additional, in lots of situations the syntactical and, specifically, semantic definitions of BPMN are erroneous, incomplete or inconsistent. The ebook addresses concrete matters about the execution semantics of industrial approaches and offers a proper definition of BPMN technique diagrams, that may function a valid foundation for additional extensions, i.e., within the type of horizontal refinements of the center language.

To this finish, the summary kingdom computer (ASMs) process is used to formalize the semantics of BPMN. ASMs have established their worth in a variety of domain names, e.g. specifying the semantics of programming or modeling languages, verifying the specification of the Java digital desktop, or formalizing the ITIL swap administration process.

This form of development promotes extra consistency within the interpretation of accomplished versions, in addition to genuine exchangeability of versions among diversified instruments. within the outlook on the finish of the ebook, the authors finish with providing extensions that deal with actor modeling (including an intuitive option to denote permissions and obligations), integration of user-centric perspectives, a polished communique inspiration, and knowledge integration.

Example text

Such a change is stated by one or more updates of the form myFunction(parameter1, parameter2, : : :) := newValue newValue can thereby also be calculated from the old value in this location, as in “f(x) := f(x) C 1”. One state transition is affected by a set of such updates, all of which are supposed to be performed simultaneously. For instance, the following is a possible update set for our simple example: { lifecycleState(InstanceA, Activity1) := " Com pl et ed " , add newToken(InstanceB) to tokensInSequenceFlow(SequenceFlow2) } whereby the latter update statement abbreviates: tokensInSequenceFlow(SequenceFlow2) := tokensInSequenceFlow(SequenceFlow2) [ {newToken(InstanceB)} In contrast to most other state-based methods, there is no need to explicitly state that the values in certain locations remain the same as before.

The BPMN standard provides start events for this, but the question is left open how exactly such a start event is triggered. However, this must be clarified if models shall be transferrable from one tool to another. There are two major alternatives for triggering a start event to create a new process instance: either triggers are directly delivered by the environment to the right start event or triggers are issued into a pool where start events regularly check for appropriate triggers. g. on behalf of a user who wants to choose between different messages which are concurrently available.

Rule CreateInstance : flowNodes instances correlationInfo ! 2 Deleting Instances The rule DeleteInstance removes the given instance from the active instances of the given flow node and adds it to closedInstances. Note that a completed instance may still be needed—in particular, for compensation. 3 Interrupting Activities Activities can take an indeterminate time to complete and are not even guaranteed to complete ever. While an instance of an activity is running, conditions in its environment (in the parent instance) may change such that the instance becomes obsolete.
