1. An operating machine constituted by a plurality of components, said operating machine comprising:

  • a storage unit which stores an operation history of a target component included in said plurality of components and targeted for life span estimation, a discrimination threshold value used for classifying usage of said target component into a plurality of usage modes based on said operation history, and a usage mode-specific estimated life span indicative of an estimated life span of said target component in each of said usage modes; and

    an arithmetic and control unit which performs a process of calculating an operating time of said target component in each of said usage modes by classifying said operation history of said target component in accordance with said discrimination threshold value, and a process of estimating the life span of said target component based on the operating time of said target component calculated for each of said usage modes in the aforementioned process and on said usage mode-specific estimated life span;

    wherein said usage mode-specific estimated life span is calculated on the basis of the operating times of a plurality of replaced components of the same type as the type of said target component in each of said usage modes.
