    摘要: A method for extracting as knowledge causal relationships between input variables and an output variable of a neural circuit model, said neural circuit model being of a hierarchical structure constructed of an input layer, at least one hidden layer and an output layer and having performed learning a limited number of times by determining weight factors between mutually-connected neuron element models in different layers of the input layer, hidden layer and output layer, wherein with respect to plural routes extending from a neuron element model, corresponding to a particular input variable, of the input layer to a neuron element model, corresponding to a particular output variable, of the output layer by way of the individual neuron element models of the hidden layer, a product of the weight factors for each of the routes is determined, and the products for the plural routes are summed, whereby the sum is employed as a measure for the determination of the causal relationship between the particular input variable and the particular output variable.

    摘要: In order to operate a plurality of utilities (2,3,4,5), the utilities (2,3,4,5) are interconnected via a communication path (11). Each utility (2,3,4,5) has a control device (1) for controlling the utility (2,3,4,5) and a memory (12) for storing information factors which are used by the corresponding control device (10). The information factors corresponding to all the utilities (2,3,4,5) are investigated by an extraction device (13) to determine which are common to the utilities (2,3,4,5) and which are related. Where the common information factors are identified, they are passed by the communication path (11) to the memories (12) of all the utilities (2,3,4,5). Similarly, when related information factors are found, a calculating device (14) calculates common information which is also passed via the communication path (11) to the memories (12) of all the utilities (2,3,4,5). In this way, utilities (2,3,4,5) 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 (2,3,4,5) or carried out by a common control device (6). The utilities (2,3,4,5) may be electric power supply systems, district heating and cooling systems, sewage disposal systems, waste recovery systems, etc.
