  • Ontology as a Term System of BPMN Notation

    Abstract:
    Introduction. Business Process Model and Notation (BPMN) is widely used standard for modeling business processes and supported by the Object-Oriented Technology Specification Management Group (OMG). However, the BPMN 2.0 specification is quite lengthy and contains over 500 pages. Item definitions are scattered across different sections of the specification and sometimes conflict. In addition, the structure of elements and their relationships are described in the form of metamodel, but further syntactic rules are defined within the natural language text. The purpose. This article proposes an ontology that formally represents the BPMN specification. The item description is consolidated within the appropriate class, and further explanations are provided in the annotations. The taxonomic structure in an ontology provides navigation through concepts in is-a relationships. Methods. A possible way to organize terminological vocabulary is the construction of ontologies, terminological systems and the creation of terminological data banks. The open source Protégé ontology editor was chosen to form the ontology. The correctness of the resulting terminology is partly ensured by the Reasoner included in Protégé. Results. The ontology of BPMN 2.0 notation can be used in the educational process as reference, as well as to control knowledge. In addition, ontology can be used as tool for solving semantic search problems. A potentially interesting result can also be an automated synthesis procedure based on the proposed ontology of questions for tests in the LMS Moodle system or similar.

  • Executable Business Process Modeling

    Research Article
    Development of education No 1 (7)

    Abstract:
    As noted in the explanatory note to the «Information Systems Specialist» professional standard, the success of implementing information systems is largely determined by the accuracy of their adaptation to the business processes of the customer organization. Today, BPMN notation is often used as a tool for extracting requirements for information systems. BPMN provides executable semantics that make it possible not only to draw up a detailed specification of a business process, but also to model it with numerical estimates. The aims of this study are to choose tools for teaching students from the number provided by BPMN notation: descriptive, analytical and executable, which allow to implement the third level of modeling; to define a methodology for teaching business modeling, including the ability to execute business processes in the universal BPMN runtimes and as an add-on on the configuration of the information system. The following methods have been used: comparative analysis and testing of the functionality provided for the development of business processes in the Bizagi and 1C: Enterprise tool environments, including the creation of the data and presentation layers necessary for BPMN execution. As a result, the main stages of business modeling are formulated, a functional comparison of tools for working at the following stages has been carried out: development of a business process model; development of a data layer that supports the execution of the process; mapping data to process tasks – forms of user tasks; programming business rules governing the process; execution of a business process by user-performer. The peculiarity of 1C: Enterprise is that the business process is essentially a superstructure over the layers of data and representations of the finished configuration of a process-oriented information system. The authors believe that both the first and the second approach deserve attention in terms of the educational process at the university for students of 09.03.02 «Information systems and technologies» specialty.
