Designing Optimal Enterprise Architecture for Digital Industry: State and Prospects

This article discusses the formation of a rational Enterprise Architecture (EA) of the digital industry. The aim of the article is to draw the attention of the scientific community to the issue of using EA in the Industry 4.0 concept. The relevance of the article is that the use of a rational AP will help to effectively transfer the enterprise to the digital industry. Increasing the efficiency of the enterprise in the modern digital world is achieved through the use of “cross-cutting” indicators, which will be contained in several architectural representations. A set of metrics is proposed to represent the formalization and mathematical measurement of EA. The enterprise architecture is a process of collecting and disseminating information about how an organization uses and should use IT in its activities. The application of architectural models, in particular the Zachman' model, allows implementing a systematic approach in the field of solving the enterprise's problems from the point of view of information technologies in the digital industry. With the help of the set theory, EA is represented as a tuple of 8 elements, which contains sets of requirements, business processes, business systems, data elements, applications, technologies, constraints and business rules, as well as a corresponding set of indicators and their meanings. A set of main components of the EA is determined and the indicators of their measurement are given. In this paper, it is shown that there is a need for a variety of proposals for architectural representations, and this article is one of such representations that can contribute to the formation of “standards” of EA, including the attributes of architecture, their definition and measurement of value, ie metric form and scale. In the digital industry, there is a need for “architecture repositories” that use the same set of standards for organizing, storing, and extracting knowledge of architecture.
