  • Expert system capable of meeting real time constraints
    Patent number: 5412753
    Abstract: An expert system capable of meeting real time constraints for solving a problem on the basis of a flow of input messages concerning the operation and the status of a network of machines, this status changing with time, includes a filter module detecting in real time significant events on the basis of input messages, each significant event being a manifestation of a problem, as judged by a human expert. A database stores all input messages, the significant events defined by the filter module, intermediate data produced by the expert system, data constituting a model of the network of machines and archives relating to problems processed previously, whether solved or not.
