Component management device, component management method, and non-transitory storage medium

A component management method for managing a threshold value related to a used amount of replaceable components, comprising:

• detecting, by a detector, a first-class component whose used amount exceeds the threshold value and which is used without causing a failure, based on component information related to the used amount and failure information related to a failure occurrence with respect to the first-class component in a component management device including the first-class component, and detecting a first-class device including the detected first-class component and not causing a failure related to the first-class component;
• determining, by a processor, the presence or absence of a correlation with respect to a first correlation between the used amount of the detected first-class component and an operating condition of the first-class device;
• and
• determining, by the processor, a first update value of the threshold value based on the used amount of the first-class component in the first-class device when no correlation for the first correlation is determined;
• wherein the first-class component has the number of components whose used amount exceeds the threshold value and which is used without causing a failure exceeds a certain ratio of the total.

A non-transitory storage medium that stores a computer program for operating a computer as a component management device that manages a threshold value related to a used amount of replaceable components, comprising:

• a detection component configured to detect a first-class component whose used amount exceeds the threshold value and which is used without causing a failure, based on component information related to the used amount and failure information related to a failure occurrence with respect to the first-class component in the component management device including the first-class component, and to detect a first-class device including the detected first-class component and not causing a failure related to the first-class component;
• a correlation determination component configured to determine the presence or absence of a correlation with respect to a first correlation between the used amount of the detected first-class component and an operating condition of the first-class device;
• and
• an update component configured to determine a first update value of the threshold value based on the used amount of the first-class component in the first-class device when no correlation for the first correlation is determined;
• wherein the second-class component has the number of components whose used amount exceeds the threshold value and which has a failure occurrence exceeding a certain ratio of the total.
