PURPOSE:To obtain a solution which is close to an optimum one in a short time by calculating a value corresponding to whether each generator at each point is operated or not by using a neural network and then performing calculation so that an energy function becomes a minimum based on a sum of the calculation result. CONSTITUTION:A model-creation mechanism 12 creates a model of a neural net based on a content of a data-description portion 11. A demand at each power plant is described in the data-description portion 11. The model-creation mechanism 12 defines a neuron corresponding to an element of a schedule matrix and expresses constraint conditions and an evaluation function using an energy function, thus enabling a connection coefficient between the neurons to be determined according to a coefficient matrix. Then. a neural network operation mechanism 16 performs calculation based on the neural network model which is created by the model creation mechanism 12 and an initial value which is set by an initial-value setting mechanism 13 and allows the neural network to be operated. |
