PLANT OPERATION SCHEDULE CALCULATION METHOD

PURPOSE:To always perform accurate operation schedule calculation secularly by collecting real operation data with respect to the quantity of state of a plant, and correcting a plant characteristic function sequentially automatically. CONSTITUTION:In a schedule calculation routine 2 in a schedule calculation method 1, the state quantity of the plant and a targeted time at the time of starting schedule calculation are read in, and the schedule calculation is repeated until a difference between the targeted time and a scheduled time arrives at an allowable value. In a plant characteristic function correction routine 3, the real operation data is read in at a time when the operating state of the plant is set, and it is arranged and accumulated as plant characteristic data, and the automatic correction of the plant characteristic function is performed by using the plant characteristic data at the time of completing the collection of data. And the state quantity of the plant in future is estimated from the present quantity of state of the plant in the routine 2 by using the latest plant characteristic function data 4 on which automatic correction is applied.
