Weak Conformance Between Process Models And Synchronized Object Life Cycles

Weak conformance between process models and synchronized object life cycles

Process models specify behavioral execution constraints between activities as well as between activities and data objects. A data object is characterized by its states and state transitions represented as object life cycle. For process execution, all behavioral execution constraints must be correct. Correctness can be verified via soundness checking which currently only considers control flow information. For data correctness, conformance between a process model and its object life cycles is checked. Current approaches abstract from dependencies between multiple data objects and require fully specified process models although, in real-world process repositories, often underspecified models are found. Coping with these issues, we introduce the concept of synchronized object life cycles and we define a mapping of data constraints of a process model to Petri nets extending an existing mapping. Further, we apply the notion of weak conformance to process models to tell whether each time an activity needs to access a data object in a particular state, it is guaranteed that the data object is in or can reach the expected state. Then, we introduce an algorithm for an integrated verification of control flow correctness and weak data conformance using soundness checking.

Service-Oriented Computing

This book constitutes the refereed conference proceedings of the 12th International Conference on Service-Oriented Computing, ICSOC 2014, held in Paris, France, in November 2014. The 25 full and 26 short papers presented were carefully reviewed and selected from 180 submissions. The papers are organized in topical sections on business process management; service composition and discovery; service design, description and evolution; cloud and business service management; ensuring composition properties; quality of service; semantic web services; service management; cloud service management; business service management; trust; service design and description.
