ANOMALIE W MODELOWANIU PROCESÓW BIZNESOWYCH

In the field of business process modeling the most popular is the Business Process Modeling Notation (BPMN). BPMN is relevant from a practical point of view while at the same it offers many challenges for software developers and scientists. Specification of a BPMN diagram is relatively precise, but it is only a descriptive form presented at some abstract, graphical level. Most of the work in this area is focused on the use of the possibilities offered by BPMN notation. However, there is still no document analyzing the errors and how to detect and eliminate. The article attempts to analyze issues anomalies that may occur in the BPMN notation. The survey is based on the analysis of literature and own experience of modeling in BPMN. Analyzes allowed us to identify a few of the most common types of anomalies: syntactic anomalies, and structural anomalies.W dziedzinie procesów biznesowych najbardziej popularne jest modelowanie Business Process Modeling Notation (BPMN). BPMN jest istotny z praktycznego punktu widzenia, a przy tym oferuje wiele wyzwań dla programistów i naukowców. Specyfikacja diagramu BPMN jest stosunkowo precyzyjna, ale jest to tylko forma opisowa prezentowana na abstrakcyjnym poziomie graficznym. Większość prac w tym obszarze skoncentrowanych jest na wykorzystaniu możliwości, jakie oferuje notacja BPMN. Jednak wciąż nie ma dokumentów analizujących ewentualne błędy oraz sposoby ich wykrywania i eliminowania. Celem artykułu jest próba analizy zagadnienia anomalii, które mogą wystąpić w notacji BPMN. Badanie opiera się na analizie literatury oraz własnym doświadczeniu z modelowania w języku BPMN. Przeprowadzone analizy pozwoliły na zidentyfikowanie kilku najczęściej występujących rodzajów anomalii: strukturalnych i składniowych

Identification and resolution of anomalies in process models using patterns

Modeliranje procesa i metodološka istraživanja modeliranja funkcionalnosti (funkcija, procesa, aktivnosti, operacija, itd.) provode se od početaka razvoja i primjene računala. Pritom su predmet interesa metode i tehnike modeliranja, ali i anomalije modela te njihovo otkrivanje i otklanjanje. Suvremene servisno orijentirane arhitekture, razvoj vođen transformacijom modela i općenito težnja prema automatiziranom razvoju, daju novu važnost istraživanjima anomalija modela procesa i drugih modela funkcionalnosti. Rad se bavi istraživanjem anomalija u modelima procesa, njihovim osobinama, zajedničkim obilježjima, podjelom, metodama i metodikama prepoznavanja, te rješavanja uz primjenu uzoraka. Temeljni pristup otkrivanja i rješavanja anomalija u radu je formiranje taksonomije anomalija, te opis njihovih svojstava i uzoraka. Namjera je da se za svaku klasu anomalija odrede metode otkrivanja i rješavanja, s ciljem automatizacije prepoznavanja i rješavanja anomalija.Anomalies in business process models represent situations in which there is a deviation from the rules of modeling and presentation models. Anomalies are departures from the expected or normal structure, behavior, functionality, performance and etc. Since anomalies have certain common properties and characteristics by which they can be grouped and classified, we can say that the anomalies are actually patterns that cause deviations from normal behavior model and need to be cleared. A model in which exists an anomaly is defective and requires additional intervention which corrects this model. Anomalies in the models of business processes can occur during: modeling, modify models and conversion models. Problems with anomalies especially come to the fore in the case of conversion models from one notation to another. In this case, different uses of specific notation usually dictate and emphasis details on individual elements of the model. For this reason, may cause loss of information during this transformation. This paper deals with anomalies in the models of business processes, their properties, characteristics and features, by developing their taxonomy, the ways of their recognition and ways of their solution. This paper presents an overview of anomalies, which are classified according to certain characteristics. For each anomaly is given a description and example. He also suggested a way to identify and solve, in the form of OCL rules or in pseudo-code. Finally worked out a proposal automation to identify and solve anomalies based on pattern recognition, and our model is tested on several examples

BUSINESS PROCESS MODEL ANTI-PATTERNS: A BIBLIOGRAPHY AND TAXONOMY OF PUBLISHED WORK

Patterns have been proven to be useful for documenting reusable solutions to common problems. A recently published bibliography of business process model patterns shed light into the various types of patterns by providing a systematic categorization of these patterns. In this way, such classification improves the understanding of business process model patterns. Anti-patterns document a counterproductive solution to a commonly occurring problem. While a classification for the large body of literature on business process model patterns is available, a structured bibliography of anti-patterns is missing. Related work on anti-patterns discusses patterns for common modeling errors, problems in business process models as well as in the business processes. Modeling experts should be aware of all these types of anti-patterns. To fill this gap, this paper presents a bibliography of business process model anti-patterns and a taxonomy of anti-patterns that has been developed using an established approach for taxonomy development. Both are based on an literature review and are valuable for people during the design and analysis phases of business processes since knowledge about anti-patterns in business process models helps for increasing their quality. Our overview should also be useful for developers of modeling tools who wish to make the modeler aware of potential modeling problems
