To provide increasing of effectiveness of industrial systems with achievement of the guaranteed product quality, the manufacturing digital transformation paradigm is applied. According to Industry 4.0 concept, adaptive, client-oriented automatic control of product life cycle is the basic approach in global manufacturing digitalization. Such technologies as Big Data, Cloud Services, advanced analytic algorithms, have to be implemented to provide an effective control for complex technological processes. Therefore, different technologies operating information from Web as well as from field level and top level manufacture information systems should offer high degree of interoperability. This article represents the, so-called, digital twin concept description. The main development issues and paradigms are described, applying to oil refining industry.

The article states that today in industry 4.0 are widely used automated and computerized control systems of industrial processes of the enterprise. It is stated that one of the types of such systems are MES-systems. The most popular MES-systems are presented, and it is revealed that the use of such systems in the service of the quality of the enterprise will improve the competitiveness of the enterprise. It is specified that the MES-system “FOBOS” is suitable for implementation in departments of quality service of the enterprise, the main advantages and opportunities of this MES-system are described. The article suggested that in order to exclude the possibility of unauthorized access to the MES-system, it is necessary to introduce an information security system. The main ways to ensure the security of data contained in the system are indicated. In conclusion, it is emphasized that the use of optimization and automation of the enterprise is an important step in the context of the transition to industry 4.0.
