摘要： In a plant for which process control is made, a margin of an operation allowable limit for a process variable is variably established according to situations for each apparatus constituting the plant. In addition, allowable upper limits of operation considering a life consumption state and an operation schedule of each apparatus are established for respective apparatus on the basis of a life of the whole plant. The life of each apparatus and the life of the whole plant are controlled with a goal to expire all equipment substantially at the same time by reflecting the allowable operating conditions of the apparatus constituting the plant on the plant control. Therefore, it is possible to realize rational and useful plant operation.

摘要： A consumer load receiving power from a power system is divided into a first load to which power may be interrupted if necessary to reduce demand on the power system, and a second load to which power supply may not be interrupted to reduce demand on the power system. When it is necessary to reduce demand on the power system, the power system sends a load control signal to a controller at the consumer indicating that supply of power to the first load is to be interrupted. In response to the load control signal, the controller interrupts supply of power from the power system to the first load, thereby reducing demand on the power system.

摘要： In an expert system of an operating system e.g. an industrial plant it is desired to input data in the form of relationships between operating parameters of the system to a database. However, if such data are input by inexperienced users, there is the possibility of incorrect data being input. Therefore, a memory stores a plurality of fundamental rules, each being a predetermined relationship between the operating parameters. Then when a datum is input, the fundamental rule(s) corresponding to the operating parameters of the datum are investigated, and the datum is transmitted to the database when each such corresponding fundamental rule is satisfied. In a further development, prevent transmitting datum to a database when each such corresponding fundamental rule is not satisfied.
