Abstract

Industry 4.0 is an actively developing concept, of which the concept of the Digital Twin is becoming a part. The digital twin is a complex cyber-physical system that consists of many components. One of the main tasks in the construction of a twin is to organize the interaction of the parts of the twin with each other. Previously, an approach called the enterprise service bus was used, but over the years of its use it became clear that it is not suitable for constantly evolving and growing systems. The digital twin is just such a system and therefore it is required to use a different approach, called microservice. If we imagine the parts of the twin as a set of microservices, then it will be possible to create a system suitable for constant evolution and replacement of its parts. This approach was used to solve the problem of building a prototype digital twin of methanol production. The solution of this problem showed the possibility of using a microservice approach.
