Аннотация: To solve the problem of inertia of enterprise information systems, the architecture of an integrated information system based on a service-oriented architecture is proposed. The stages of building an information system for object-process control are proposed. The architecture is shown and the modules of the integrated information-control system are described. A feature of the proposed architecture is a set of services that ensure the performance of tasks in the face of changing organizational goals, combining both homogeneous and heterogeneous software.
