Abstract: An automatic analysis system includes: a plurality of automatic analyzers; a conveyance line connected to the analyzers; and a computer configured to control the conveyance line to distribute a sample to the automatic analyzers. Each of the automatic analyzers includes a first component that is constantly used and a second component that is intermittently used. The computer is configured to compare a usage time of the first component of each automatic analyzer with a set time, select, when the usage time of the first component of any one of the plurality of automatic analyzers exceeds the set time, the automatic analyzer in which the usage time of the first component exceeds the set time as a prioritized device, and control the conveyance line such that a sample used for analysis in the second component is conveyed to the prioritized device in preference to another automatic analyzer.
