The method of automated implementation of the theory of constraints in the functioning of a petrochemical enterprise

Automation, digitalization, blockchain. These categories have become key in the modern economy and determine the vector of competitive development of industrial enterprises. An important problem remains finding funds for the transformation of the entire production system, as well as identifying the most vulnerable and weak links in the management system of an industrial enterprise. Based on this, the development of a universal methodology, implemented in particular through the use of Data Mining, attracts attention. This predetermined the choice of the topic, object and subject of the study, on the basis of which the purpose of the study is formulated - the development of a methodology for identifying limitations (“strong” and “weak” places) in the functioning of a petrochemical enterprise, adapted to Industry 4.0. Within the framework of achieving the goal, such research methods as formalization (in terms of building a SCOR model of the supply chain of petrochemical products), comparison (in the context of evaluating and comparing the dynamics of development of various industrial enterprises), the coefficient method (laid the basis of the author’s universal methodology for evaluating business processes) are used. As a result of the research, the following scientific results were obtained: a formalized SCOR model of the supply chain of petrochemical products was proposed, supplemented by general indicators for evaluating business processes (the first level), which allows linking the results of the activity of an industrial enterprise with these business processes; patterns of development of petrochemical enterprises of the Republic of Tatarstan - PJSC Nizhnekamskneftekhim and JSC Nizhnekamsk Carbon black Plant, characterized by more efficient functioning of the latter, including in the crisis conditions of 2020, were revealed; a comprehensive method (of the first level) of automated detection of restrictions in the functioning of a petrochemical enterprise, tested on the example of petrochemical enterprises, is proposed; a blockchain scheme is proposed in the management of the main business processes of an industrial enterprise. The inclusion of the methodology in the instructional and methodological materials for managing business processes of industrial enterprises will ensure the maximum possible effect as a result of building a data collection system based on the principles of blockchain.
