Abstract
In order to operate a plurality of utilities, the utilities are interconnected via a communication path. Each utility has a control device for controlling the utility and a memory for storing information factors which are used by the corresponding control device. The information factors corresponding to all the utilities are investigated by an extraction device to determine which are common to the utilities and which are related. Where the common information factors are identified, they are passed by the communication path to the memories of all the utilities. Similarly, when related information factors are found, a calculating device calculates common information which is also passed via the communication path to the memories of all the utilities. In this way, the utilities may operate more efficiently than when they are operated on a stand-alone basis. The investigation of the information factors, and the calculating of common information from related information factors may be distributed among the utilities or carried out by a common control device. The utilities may be electric power supply systems, district heating and cooling systems, sewage disposal systems, waste recovery systems, etc.
