The paper proposes a process mining method for analysis of EDRMS workflow processes. The method is based on the analysis of document action logs. It is assumed that an “empty” system is put in the enterprise without descriptions of workflows and users perform familiar actions in manual mode.

After processing several documents of the same type, the journal becomes “complete”, which allows reconstructing the intended document processing process. After reviewing the received process by the analyst and making changes, the process can be loaded into the system and the appointment of the passage of all instances by the document will be automated.

The study proposes the following scheme for the reconstruction of the listed projections of the BPMN model - the workflow process:

event log segmentation by document type;
segmentation of received logs by stages of the document life cycle;
reconstruction of the control flow projection;
reconstruction of the projection of resources;
reconstruction of data projection and decision making.

The need for the first step is due to the fact that several types of workflows can be associated with a single type of document in a journal. The second step allows you to separate the event traces of processing a single document. The splitting is based on the life cycle stages of the document type. After selecting a set of traces, in the next step, the projection of the workflow control flow of the modified alpha-plus algorithm is reconstructed, which allows to obtain a BPMN-graph of the process as a result. In the next step, to ensure the reconstruction of the projection of resources, the tree of the organizational structure is used, in which the intermediate nodes are organizational units and positions, and the leaves are officials. Reconstruction is carried out on the basis of the proposed heuristic rules. The data projection reconstructed in the next step, describing the main attributes of the process instance, corresponds to the registration card of the document. The paper proposes a procedure for identifying delegates for controlling the behavior of exclusive process gateways. For each exclusive gateway, obtained during the reconstruction of the flow control model according to the log, a pair of predicates is built on expressions of comparisons of the attributes of the registration card. The construction of these predicates was performed by an algorithm for the automatic construction of decision trees.

The above methods for the reconstruction of the projections of process models were implemented as a component in the composition of BPMN - the editor of workflow processes.
