Abstract

A real time status monitoring method for inputting randomly varying data relating to a plurality of objects, processing a plurality of functions having some of the data as variables and monitoring an overall status including the objects on a real time basis, and an apparatus therefor are disclosed. A table indicating the presence or absence of data change in the objects and the presence or absence of variables related to the data change in the funtions is prepared. In processing the functions, the table is referenced and only those functions which include the variables related to the data change are processed.

Claims

inputting randomly varying data relating to a plurality of types of objects;

grouping the data;

preparing and grouping real time status management tables indicating which ones of the data comprise variables for a plurality of functions;

generating group data change flags indicating which grouping of the data has been changed by detecting reception of the data;

determining the variables which are subjects of processing due to data reception and types of functions which include the variables based on a function processing end flag indicating on which ones of the data the processing of the functions has been completed, and the group data change flags;

processing only those functions which include the variables which are subjects of processing due to the data reception, based on the determining;

generating the function processing end flag indicating on which ones of the data the processing of the functions has been completed; and

displaying a processing result of the functions.

4. A real time status monitoring method according to claim 3 wherein said data are grouped in accordance with a frequency of data change for the plurality of types of objects.

5. A real time status monitoring method, the method comprising the steps of:

inputting randomly varying data relating to a plurality of types of objects,

grouping the data;

dividing a plurality of functions including some of the data as variables into a plurality of types of sub-functions in accordance with the grouping of the input data;

preparing a management table indicating which ones of the sub-functions the functions use for processing;

generating signal flags indicating which ones of the sub-functions have a data reception;

determining which sub-functions are subjects of processing and types of functions which include such sub-functions based on a decision making support information change flag indicating on which ones of the sub-functions the processing of the function has been completed and the signal flags;

processing only those functions which include the sub-functions which are subjects of processing due to the data reception, in accordance with the determining;

generating the decision making support information change flag indicating which ones of the sub-functions the processing of functions have been completed; and

displaying a processing result of the functions.

6. A real time status monitoring method, the method comprising the steps of:

inputting randomly varying time serial data relating to a plurality of types of objects;

dividing the time serial data into a first data component relating to current real time data and a second data component relating only to past time serial data;

preparing a management table indicating if the first data component and the second data component comprise variables for a plurality of functions for processing;

generating data change flags indicating which of the first and second data components have been inputted by detecting reception of the time serial data;

fetching a processing result for the second data component from a memory area;

processing the first data component, when the first data component is determined to be a subject for processing due to the data reception, based on the data change flags;

processing the functions by consolidating the processing result for the first data component and the processing result for the second data component by using the management table; and

displaying a processing result of said processing the functions.

7. A real time status monitoring system comprising:
