Abstract: A selection support device that supports selection of a work machine to be used for work from among a plurality of work machines, the selection support device including: a history information acquisition unit configured to acquire history information on a use history of each work machine; a specifying unit configured to specify a degree of use of each work machine based on the history information; and a selection unit configured to preferentially select a work machine with a small degree of use as a work machine to be used for work.

Abstract: The storage unit stores history information in which area information regarding a past work area and time information regarding a work time in the past work area are associated with each other. The acquisition unit acquires area information regarding a current work area. The identification unit identifies a degree of association between the area information acquired by the acquisition unit and the history information stored in the storage unit. The output unit outputs information included in the history information with priority according to the degree of association identified by the identification unit.

Abstract: The acquisition unit acquires area information regarding a current work area. The prediction unit predicts a work time in the current work area on the basis of the area information acquired by the acquisition unit and history information in which area information regarding a past work area and time information regarding a work time in the past work area are associated with each other.

Abstract: A display control system includes: at least a display control device including a transparency control unit that, when displaying a first display component and a second display component such that at least parts of the first display component and the second display component overlap each other, increases a transparency of at least one of the first display component and the second display component in an overlapping portion according to one of a density of display contents contained in the first display component and a density of display contents contained in the second display component in the overlapping portion.

Abstract: A display system includes at least a display device. The display device includes a processor configured to execute a process including: identifying a processing period and a waiting period of a first device and a processing period and a waiting period of a second device based on log information of processing in the first device and log information of processing in the second device that performs processing subsequent to the first device; arranging the processing period and the waiting period of the first device identified on a first time axis that indicates changes of the processing period and the waiting period in the first device; calculating a distance between the first time axis and a second time axis; and displaying a graph in which transitions of the processing period and the waiting period are expressed with different band stripes based on the distance calculated.

Abstract: [Issue] A chamfering method is provided that can be conducted even in small worksite space without using grinding members and without requiring a cleaning process after a chamfering process. [Resolution Means] A brittle material substrate chamfering method according to the present invention includes steps of drawing a scribing line, and heating and/or cooling a part in proximity to the scribing line. The scribing line is drawn on a part of a surface of a brittle material substrate that extends along the edge of the brittle material substrate and has a width not more than 50% of the thickness of the brittle material substrate starting from the edge of the brittle material substrate whereby forming a crack inclined from the surface of the substrate toward a side end surface of the substrate. A part in proximity to the scribing line is heated and/or cooled so that a corner part of the edge of said brittle material substrate is cut out whereby chamfering said brittle material substrate.
