Information processing system, component lifetime determining method, and non-transitory recording medium

A component lifetime determining method for determining lifetimes of components, to be replaced by preventive maintenance, of respective electric devices, the component lifetime determining method comprising:

• specifying, based on variables that represent use states of the electric devices and failure data of the electric devices which have been obtained from the electric devices including the components, a plurality of leading variables relevant to the lifetimes of the components;
• classifying a plurality of values of each of the leading variables into sections to create a lifetime matrix in which the lifetimes of the components are set with respect to combinations of the sections each of which relates to a different leading variable;
• and
• obtaining, from the lifetime matrix, the lifetimes of the components corresponding to the combinations of the sections each of which relates to the different leading variable to determine the lifetimes of the components with respect to the respective electric devices.

A non-transitory recording medium for causing one or more information processing apparatuses determining lifetimes of components, to be replaced by preventive maintenance, of respective electric devices, to execute a process, the process comprising:

• specifying, based on variables that represent use states of the electric devices and failure data of the electric devices which have been obtained from the electric devices including the components, a plurality of leading variables relevant to the lifetimes of the components;
• classifying a plurality of values of each of the leading variables into sections to create a lifetime matrix in which the lifetimes of the components are set with respect to combinations of the sections each of which relates to a different leading variable;
• and
• obtaining, from the lifetime matrix, the lifetimes of the components corresponding to the combinations of the sections each of which relates to the different leading variable to determine the lifetimes of the components with respect to the respective electric devices.
