Automatic analyzer and method thereof

An automatic analysis method of an automatic analyzer,

• the automatic analyzer including:
• an incubator that includes a plurality of holding portions holding a plurality of reaction containers and promotes a reaction of a mixed solution of a sample and a reagent, the reaction containers containing the mixed solution;
• and
• an analyzing unit that performs analysis on the mixed solution contained in each of the reaction containers by installing the reaction container, in which the predetermined reagent is added to the sample at a predetermined timing based on analysis information relating to a measurement item of the sample, in the holding portion and operating a measurement sequence at a predetermined reaction time, wherein
• in a case where an analysis schedule to be performed by the analyzing unit based on analysis information of the sample that is requested to be measured is created, at a time of analyzing a plurality of different measurement items, an analysis schedule of an analysis target is estimated and created according to a plurality of different measurement sequences of the measurement items such that the different measurement sequences are capable of being performed.
