Annotation:

The authors of the article consider the methodology of production flow models application at enterprises such as refineries/petrochemical complexes. Their operation shows what should be used for guiding when modernizing the model, responding to the current reengineering of business processes in production. It is proposed to follow five interrelated principles "5A", which form a feedback loop, which ensures the required and sufficient conditions for the model's operability during its operation. For the selected type of objects, the specifics of models for calculating current and calendar plans using the "5A" methodology are considered, and how the models are operable through the interaction of principles. The use of digital models at different levels of production management, both technological processes and workshops and the whole production, assumes the information interrelation of these models, which will lead to an increase of production efficiency and the competencies of its specialists. To this purpose reaching envisages building a network infrastructure for interaction and support of models of different levels, including a virtual team of specialists from key services of the main production with an independent coordinator at the head. The coordinator forms a virtual team of specialists and controls them monitoring "5A" cycle as well as interacts with the management of the services and the enterprise. The approach is generalized to vertically integrated oil companies and petrochemical clusters.
