Abstract

An operations control apparatus is disclosed which includes a unit for processing data for operations control of an object, which has an event controller element, a common data base element and a simulator element; a operations control data diagnosis unit; a management element for checking the processing of the respective elements in response to the state of the object, to prepare the optimum processing order of the respective elements and for instructing the same to the event controller elements; a failure mode and effect analysis sheet preparing and correcting element; and a diagnosis rules preparing and correcting element.

Claims

1. An operations control apparatus including a data processing unit for processing data for operations control of an object, said data processing unit including an event controller means, a common data base means and a simulation means, and a data diagnosis unit connected to said processing unit, for diagnosing said data for operations control, said data diagnosis unit including a diagnosis means, said operations control apparatus further comprising:

a management means for checking the processing order of the respective means in response to the state of said object which is varying with respect to time, to prepare the optimum processing order of the respective means, and for instructing the same to said event controller means;

a failure mode and effect analysis sheet preparing and correcting means for predictively analyzing a failure mode and effect of said object, and for preparing and correcting a sheet representing the results of analysis; and

a means for preparing and correcting diagnosis rules in accordance with said sheet of the analysis results.

2. An operations control apparatus as claimed in claim 1, wherein said object is an artificial satellite.

3. An operations control apparatus as claimed in claim 1, wherein said management means includes:

means defining a learning section for acquiring and learning knowledge for operations control from the data which are output to said management means from said event controller means, said common data base means, said simulation means, said diagnosis means and said failure mode and effect analysis sheet preparing and correcting means, respectively;

means defining a knowledge base section for accumulating the knowledge relating to said object and knowledge for operations control generated by said learning section; and

means defining an inference section for performing inferences using the knowledge accumulated in said knowledge base section.

4. An operations control apparatus as claimed in claim 3, wherein said knowledge contained in said knowledge base section comprises past design and operations control information, newly acquired operations control information, information acquired by learning, and information on design models.

5. An operations control apparatus as claimed in claim 1, further comprising an operation console unit connected both to said data processing unit and said diagnosis unit, which serves as an interface between an operator and said data processing unit and said diagnosis unit.
