Abstract-This paper focuses on the fog-computing concept usage in the geographically-distributed information and control systems. Fog-computing concept improves the dependability of the information and control system, system latency and the communicational environment load. The key issue of fogcomputing application to the information and control systems is the formation of device communities to solve management tasks. In the current paper the new device community forming problem model is presented and described as a multicriteria optimization problem. A brief model discussion is given, and some problem solving techniques are described.
