Abstract
Provided is a system analysis device that is able to calculate a degree of contribution of a variation pattern of time-series data to a change in state of a system, in which time dependency and spatial dependency are taken into account. A system analysis device 10 includes a detection unit 11 that detects, as a rule, a combination of observation values that is included in a plurality of pieces of time-series data and satisfies a predetermined condition, the observation values being values of indices observed while a system is operating; and a calculation unit 12 that calculates a contribution degree that is a degree of contribution of the detected rule to a change in state of the system.
Claims10
A system analysis device comprising:
- a memory storing instructions;
- and
- one or more processors configured to execute the instructions to:
- detect, as a rule, a combination of observation values that is included in a plurality of pieces of time-series data of observation values and satisfies a predetermined condition, the observation values being values of indices observed when a system is operating;
- and
- calculate a contribution degree that is a degree of contribution of the detected rule to a change in state of the system.
A system analysis method comprising:
- detecting, as a rule, a combination of observation values that is included in a plurality of pieces of time-series data of observation values and satisfies a predetermined condition, the observation values being values of indices observed when a system is operating;
- and
- calculating a contribution degree that is a degree of contribution of the detected rule to a change in state of the system.
A non-transitory computer readable storage medium recording thereon a program causing a computer to perform processes comprising:
- a detection process that detects, as a rule, a combination of observation values that is included in a plurality of pieces of time-series data of observation values and satisfies a predetermined condition, the observation values being values of indices observed when a system is operating;
- and
- a calculation process that calculates a contribution degree that is a degree of contribution of the detected rule to a change in state of the system.
