The article is devoted to the study of a complex of modern automated information systems, considered through the prism of the main tasks of operating activities of modern enterprises.

The author defines the essence and role of automated information systems in the process of enterprises functioning. Also outlined a range of aspects of operating activities that require simplification and continuous information support.

In the first place, the systems of automated design, the so-called CAD-systems, which allow an operating manager to automate design and design work and accelerate the preparation of engineering-technological documentation, are analyzed in the work.

 The author outlines the range of applications and reviews the three groups of today's most popular CAD-systems. Particular attention is paid to the analysis of functional tasks of this type of automated information systems in terms of operating activities of the enterprise.

The article gives a small historical digression to the origins and evolution of MRP, MRP II, ERP systems. The emphasis is on the ERP-system, because it allows you to integrate internal and external information of the organization, as well as support different fields of activity, not limited to one production. The author presents the most common MRP and ERP systems for the present day.

Further, the functionality of information systems that support operative management and production control, the so-called MES-systems, are described in the paper. A list of current software products of the MES-category is also presented.

The next type of automated information systems that were found in the focus of the study were process control systems, or SCADA-systems that are focused on controlling technological equipment at the site level, workshop, etc.

The scheme of the automated information management system hierarchy is developed, which allows to systematize their typical diversity in the context of the functional coverage area and the spectrum of solvable operating problems.
