Urgency of the research. Nowadays business process management is the one of the most popular management concepts. It is based on business process modeling which is used to document enterprise activities with the help of graphical business process models built using various modeling notations.

Target setting. Maintenance of the collection of business process models provides ways to their future reuse for design and improvement of enterprise business processes. Therefore, the need for support of correctness and consistency of business process models stored in the enterprise repository becomes relevant.

Actual scientific researches and issues analysis. The last open-access publications, including existing formal methods based on the representation of business process models by using coherent, directed graphs, as well as various metrics with the corresponding thresholds, are considered.

Uninvestigated parts of general matters defining. The existing formal methods allow guessing about the presence of errors, but do not allow defining their amount and place within a business process model.

The research objective. To develop the method of analysis and improvement of the control flow structure of business processes.

The statement of basic materials. Basic errors that might occur during the control flow structure of business process is formed are defined. The coefficient which allows defining the presence and amount of errors, as well as the optimization problem which solution allows elaborating recommendations for business process model improvement, are proposed. The software implementation of the method is used to validate it by analyzing sample business process models presented in various modeling notations.

Conclusions. The proposed method allows defining the presence and amount of detected errors, as well as their place within a business process model in order to their further elimination.

Key words:

business process model; modeling notations; business process model metrics; business process modeling errors; control flow of business process; analysis and improvement method.
