Structural and Functional Modeling of Processes with a Dedicated Control Subject

— The efficiency of informational support depends on the speed and quality of making management decisions, as well as their relevance and adaptability to changing conditions, which determine the efficiency of the functioning of production systems. The paper considers the development of artifacts to represent structural and functional models of organizational systems described by the set of interacting processes and subprocesses functioning under uncertainty. The creation of a new system of artifacts is caused by the necessity to distinguish the subject of management in an explicit form combining discrete and continuous processes within the framework of one model, as well as determining the efficiency of the obtained models. The eEPC, BPMN, and IDEF methodology of structural modeling served as a basis for this development. The use of the proposed system of artifacts is shown using the example of managing the product portfolio of production systems operating on a free market. The presented form of representation allows one to structure the running processes and investigate their efficiency by the methods of simulation modeling and statistical analysis.
