Process status supervisory system

A system for supervising the status of processing performed in data processing means in which the internal status of the system changes due to an input of operation information from outside the system, comprising:

• input means for inputting the operation information from outside the system;
• first storage means for intermittently storing, in accordance with a predetermined timing, information data representing the internal status of said data processing means which changes due to the input of said operation information, said predetermined timing being at a second time point which occurs according to a predetermined number of the inputs of the operation information;
• second storage means for storing said operation information in the order input and link information representing the relationship among said input operation information, said second storage means also storing corresponding file information representing whether or not there is a correspondence between said information data representing the internal status of said data processing means stored in said first storage means and said operation information input by said input means;
• and
• restoring means for restoring said data processing means to the internal status at a specific first time point, said restoring means comprising:
• retrieval means for retrieving the operation information stored in said second storage means for defining the operation which transpired from the second time point to said specific first time point in accordance with the link information and the corresponding file information, whereby the second time point is prior to the specific first time point, and the information data representing the internal status of said data processing means corresponding to said second time point stored in said first storage means;
• and
• execution means for causing said retrieved operation information that define operations which transpired from the second time point to the specific first time point to be executed again in said data processing means using the internal status of said data processing means corresponding to said second time point and for restoring said data processing means to the internal status at the specific first time point.

In an apparatus for supervising the status of processing performed in first processing means having a first knowledge base, first inference engine means for making an inference with reference to said first knowledge base and data processing means for providing control for conducting a predetermined data process in accordance with the inference made by said first inference engine means, said apparatus comprising:

• second processing means having a second knowledge base and second inference engine means for making an inference with reference to said second knowledge base for the purpose of providing further control over the predetermined data process conducted in said first processing means;
• determining means having input means for manually inputting necessary operation information for providing further control over the predetermined data process, said determining means in response to the input means determining whether or not said second processing means should provide further control over the predetermined data process conducted in said first processing means;
• and
• control means for causing said second processing means to start the predetermined data process conducted in said first processing means when said determining means determines that said second processing means is to provide further control over said first processing means or for causing said first processing system means to start the predetermined data process when said determining means determines that said second processing means is not to provide further control over said first processing means.

An apparatus for supervising the status of processing performed in a system to be supervised which comprises:

• first processing means having a first knowledge base and first inference engine means for making an inference with reference to said first knowledge base, said first processing means providing control for conducting a predetermined data process in accordance with an inference made by said first inference engine means;
• second processing means having a second knowledge base and second inference engine means for making an inference with reference to said second knowledge base for the purpose of providing further control over the predetermined process conducted in said first processing means;
• determining means having input means for manually inputting necessary operation information or providing further control over the predetermined data process, said determining means in response to the input means determining whether or not said second processing means should provide further control over the predetermined data process conducted in said first processing means;
• and
• control means for causing said second processing means to start the predetermined process conducted in said first processing means when said determining means determines that said second processing means is to provide further control over said first processing means.
