Assignee: KOMATSU LTD.
Field: Control (Instruments)
Classification: CPC E  G | IPC E  G

Claim 19:
20. An index-value determination method comprising:
providing a work machine;
acquiring state data indicating a state of the work machine at a plurality of times;
determination a classification of work of the work machine for each of the plurality of times based on the acquired state data;
determination a start point and an end point of a period related to a predetermined classification among determined classifications of works; and
obtaining an index value of the state of the work machine, the index value of the state of the work machine including at least a swing angle of the work machine in the period,
wherein, in the step of determination classification of the work of the work machine, a likelihood of each classification of the work of the work machine is acquired based on the acquired state data, and the classification of the work of the work machine for each of the plurality of times is determined based on the likelihood of each classification of the work,
the index-value determination method further comprises a step of performing smoothing process of the likelihood of each classification of the work of the work machine acquired in the step of determination classification of the work of the work machine, and
in the step of determination the start point and the end point of the period related to the predetermined classification, the start point and the end point of the period related to the predetermined classification is determined based on the likelihood in which the smoothing process is performed.
