Abstract: A method is used for selecting a boundary sample. The method includes acquiring a deterioration trend of a new device by performing a deterioration acceleration treatment to the new device, acquiring deterioration trends of a plurality of repaired devices which have been repaired after long-term use by performing a deterioration acceleration treatment to the plurality of repaired devices, calculating an upper limit of deterioration of the repaired device based on the deterioration trend of the new device, and selecting a boundary sample indicating a limit state in which the device can be reused as a standard of reuse of the device by specifying a repaired device having the largest deterioration among the repaired devices having a deterioration not larger than the upper limit.

Abstract: A method for measuring a deflection amount of a columnar structure includes the following steps. The method includes placing a longitudinal direction of a columnar structure in a direction parallel to a ground to place the columnar structure on a support member that supports the columnar structure such that the columnar structure is rotatable around an axis in the longitudinal direction; determining that the columnar structure placed has stopped rotating under its own weight around the axis; and measuring, after the stop of the rotation is determined, measuring a distance in a vertical direction between a straight line connecting both ends in the longitudinal direction of the columnar structure and a curved line along a shape in the longitudinal direction of the columnar structure.

Abstract: A facility maintenance method updates, in a case where an event having occurred in a facility is determined to fall outside a fault tree, the fault tree such that a cause of occurrence of the event identified through investigation is reflected, and in response to the identified cause of occurrence of the event, identifies a location where a structural element of equipment/material identified to relate to the cause of occurrence of the event is used, based on installation information indicating a location where the equipment/material is installed, to formulate an inspection plan for the identified location.

Abstract: A reuse support system is provided. The system includes an acquisitor which acquires skill data of workers, a grantor which grants a work license to the workers based on the acquired skill data of the workers and stores the granted work license for each of the workers in a storage, and a provider which reads the work license from the storage in response to authentication operation of the workers and provides an image according to the read work license.

Abstract: A method is used for determining reusability. The method includes receiving image data of a boundary sample and repairing method data corresponding to the image data from a database using a terminal; outputting the image data of the boundary sample for each reuse form of the device and the repairing method data using an output device; and determining whether to repair and reuse a used device by comparing a state of the recovered device with the output image of the boundary sample.

Abstract: A method for manufacturing a regenerated product includes a selection step for selecting a recovered regeneration object based on a first evaluation standard indicating a state of a surface of the regeneration object, a rust-removing step for performing a rust-removing treatment to the regeneration object selected by the selection step, and a judgement step for judging whether to terminate the rust-removing treatment in the rust-removing step based on a second evaluation standard indicating the state of the surface of the regeneration object.

Abstract: A reuse support system of an embodiment includes a display controller which displays, on a display, an image including an image of a boundary sample which serves as a reference for reuse of a facility in response to operation of a worker, an acceptor which accepts selection of a reuse mode of the facility, and a manager which manages a delivery destination of the facility based at least in part on the reuse mode of the facility selected by the acceptor.
