Analysis of business processes, namely, conducting thorough analytics of existing business processes, fixing and analyzing project histories, interviewing dozens of specialists, identifying user groups, creating characters, developing context and scenarios, mockups and prototypes of a large radio-technical enterprise, leads to a quantum leap, automation and customization of business processes and, as a whole, to increase production capacities and reduce «burning of equipment».

Workflow mining is a promising direction in the theory of project process management in CAD, it solves the inverse problem of automating the design of workflows based on diagrammatic models that are formed in it based on events about completed tasks (for example, according to the log file information). Typically, such diagrammatic models are presented in visual languages such as UML AD, BPMN, eEPC, IDEF, and others. When analyzing a project process, an expert in data mining repeatedly evaluates the diagrammatic model of the project process, changes the conditions of the project process using the characteristics of the model to achieving the optimal solution. Modeling a fragment or a complete project process is usually represented by a stream of work in graphic designs (notations). Such workflows are formalized as patterns and are reusable typical structural units of Workflow mining. It should be noted that the scope of the theory of design process management and design workflows are extensive and include human-computer interaction (for example, in industry – design preparation of production). Modern project process management systems such as SAP, PeopleSoft, Oracle, CRM (Customer Relationship Management) software apply the theory of project process management in the form of computerized technologies, modules. Modeling the project process in such systems is far from a trivial task and requires an understanding of the language for describing the project process (for example, BPMN) and a detailed discussion of the problem with the employees and management involved in the process. Mainly, Workflow mining in CAD is useful in analyzing a new system in terms of understanding how the end user (consumer, designer, programmer, expert, etc.) works with this system, while the design effects of the use of Workflow mining in the management of project processes the following:

reduces the time and cost of analysis, because most information systems have log data (log files) that are available without any additional costs; provides objective information about any accounting, since work flow logs are an impartial reflection of the work performed; allows a formal check of the properties of work flows by modeling the process before its commissioning;

supports several representations of the same project process using algorithms for the synthesis and transformation of models; allows for involuntary exit from workflow cycles (a special acyclic workflow is introduced) when necessary (for example, in case of early exit from the cycle during workflow tracing); allows multiple changes in the characteristics of the diagrammatic model on a working instance of the workflow during its execution on the basis of check points.

Thus, the task of determining the library of workflow instances in an analytical form and the formulation of a method for creating a library of instances of workflows of business processes when designing complex technical products in CAD is an urgent scientific and technical task in the theory of business process management in a large radio engineering enterprise.
