REAL-TIME INDEX CALCULATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a real-time index calculation apparatus capable of calculating and providing an index value for representing the characteristics of an event at an estimation target time in a response time required by a user without deteriorating the reliability of the index value of the calculation result.

SOLUTION: A line estimation part 2 respectively estimates time required for a calculation process of a systematic index by a calculation part 5 for an estimation target time point preset in a time series order and an estimation start time point which is a time point back as long as it takes to create its own estimation systematic information and starts a creation process of the estimation systematic information at these estimation start time points. A calculation management calculator 10 makes the calculation part 5 to start an index value calculation at a time point when the systematic estimation part 2 has created the estimation systematic information and provides a calculation result of the index value at the estimation target time point which is a provision time point.
