Monitoring and Enactment with Reactive Event Calculus

Hence, the following level mapping can be established: 1. While the total ordering assumption is reasonable when a granularity of milliseconds is chosen, it becomes questionable when shifting to a magnitude of hours or days. The three ConDec models captured in Figs. At the beginning, refuse order and accept order are blocked, because they need a previous execution of close order. Furthermore, process mining is a viable solution, because it is minimally intrusive.

A g-sciff derivation for S starting from an initial trace Ti corresponds to a sciff derivation for gen S Ti , whose termination is guaranteed by hypotheses. On the other hand, they must be prone to verification, in order to guarantee the trustworthiness and reliability of the developed model, as well as to ensure that the actual executions of the system effectively comply with it. As a consequence, a further occurring event matching with H Ev1 , T1 would trigger a new, separate propagation on the original rule.

Let us consider the ConDec model shown in Fig. Directions for a New Program. Indeed, each absence constraint triggers a negative expectation concerning the targeted activity.

Experimental Evaluation

Ebook Description Many novel application scenarios and architectures in business process management or service composition are characterized by a distribution of activities and resources, and by complex interaction and coordination dynamics. Logic Programming 37 1-3 , 1—46 1998 138. In the normal situation, the deadline is sharp, and the seller must respect it in order to comply with the choreography. An activity is said to be atomic if its execution is traced by means of a single event, non atomic otherwise. Timing aspects are not critical when the automaton is used for providing enactment facilities, because it is built once and for all before the execution phase. Indeed, composite events are complex events that do not concretely take place during the execution, but that are instead determined as a combination of concrete events, when certain circumstances are met.

This concept has been recalled in Examples 4. We have considered four challenging settings, namely Business Process Management, Clinical Guidelines, Service Oriented and Multi-Agent Systems. To facilitate readability, the parts mentioning the originator and the execution time can be omitted when the corresponding variables are not involved in any condition. Abstract The advent of distributed and heterogeneous systems has laid the foundation for the birth of new architectural paradigms, in which many separated and autonomous entities collaborate and interact to the aim of achieving complex strategic goals, impossible to be accomplished on their own. However, it is important to point out that a bounded search strategy preserves termination, but undermines completeness. Its structure is shown in Fig. Its application on three concrete and heterogeneous industrial case studies is reported.

Declarative Technologies for Open Agent Systems and Beyond. Lectures on Concurrency and Petri Nets. To understand such dynamics and to develop methods and tools apt to accommodate modeling and reasoning about them is a very challenging goal. After having discussed how the static verification task can be also interpreted as a model checking problem, we compare g-sciff with state-of-the-art explicit and symbolic model checkers, providing an empirical discussion of their benefits and drawbacks. In particular, a time structure could be: Linear vs. The explicit enumeration of the execution traces is avoided, because a ConDec diagram implicitly supports all the execution traces which comply with the modeled constraints. Systems that al- low users to maneuver within the process model or even change the model while working are considered to be the most suitable for dynamic processes management.

Abstract The advent of distributed and heterogeneous systems has laid the foundation for the birth of new architectural paradigms, in which many separated and autonomous entities collaborate and interact, with the aim of achieving complex strategic goals, impossible to be accomplished on their own. The meta model has been originally developed to address Business Process event trails, but it can seamlessly accommodate any trace produced inside an Event-Based System. The E-mail message field is required.

When providing execution support, it is not only important to offer compliance verification facilities, but also to give a constant feedback to the interacting entities, keeping them informed about the evolving state of affairs and reporting undesired situations. Closure Closure can be applied only when no other transition is applicable. In: Proceedings of the International Conference on Fifth Generation Computer Systems, pp.

Description: 1 online resource xxii, 411 pages. In the general case, activities encompass actions made by a single participants without involving the other ones e. In particular, the module applies a set of selector algorithms, which could trigger a service replacement during the execution, for example because a QoS value is under a threshold. Chapter 7 concludes this part with a discussion of related work and a summary. The intensional representation of expectations may sometimes ca fusion w.

Informatics: 10 Years Back, 10 Years Ahead. In particular, discovering a set of declarative business constraints would be useful to obtain a concise and comprehensible representation of what is going on, abstracting away from implementation details. Adherence to business constraints is not only needed due to external regulations and audit legislation. In other words, soundness requires that every formula derived from a given theory by applying the inference rules is also entailed by i. Indeed, by running g-sciff with an initial empty trace, it will terminate, returning the empty trace.
