A management system comprising a plurality of moving bodies including an autonomous moving body having an autonomous control section configured to perform autonomous movement, and a movement managing section that communicates via a communication apparatus with the plurality of moving bodies and manages movement of the plurality of moving bodies, wherein the movement managing section includes a priority/subordination determining section configured to determine a priority/subordination degree relating to the movement of each of the plurality of moving bodies, based on individual information of the plurality of moving bodies, and the autonomous moving body includes a priority/subordination comparing section configured to make a comparison between another priority/subordination degree, which is the priority/subordination degree determined by the priority/subordination determining section for another moving body that is close to the autonomous moving body and is different from the autonomous moving body among the plurality of moving bodies and which is the priority / subordination degree having been sent to the autonomous moving body by the movement managing section, and a self priority/subordination degree, which is the priority/subordination degree determined by the priority/subordination determining section for the autonomous moving body and having been sent to of the autonomous moving body by the movement managing section, or a priority/subordination receiving section configured to receive from the movement managing section a comparison result between the another priority/subordination degree and the self priority/subordination degree acquired through a comparison made by the movement managing section, the movement managing section further includes a priority/subordination adjusting section configured to adjust the priority/subordination degree when there are a plurality of moving bodies that have equal priority/subordination degrees, when there are a plurality of moving bodies that have equal priority/subordination degrees, the priority/subordination adjusting section adjusts the priority/subordination degree of a moving body for which a timing at which the priority/subordination degree was determined is a first timing to become higher than the priority/subordination degree of a moving body for which a timing at which the priority/subordination degree was determined is a second timing that is later than the first timing. a plurality of moving bodies including an autonomous moving body having an autonomous control section configured to perform autonomous movement, and a movement managing section that communicates via a communication apparatus with the plurality of moving bodies and manages movement of the plurality of moving bodies, wherein the movement managing section includes a priority/subordination determining section configured to determine a priority/subordination degree relating to the movement of each of the plurality of moving bodies, based on individual information of the plurality of moving bodies, and the autonomous moving body includes a priority/subordination comparing section configured to make a comparison between another priority/subordination degree, which is the priority/subordination degree determined by the priority/subordination determining section for another moving body that is close to the autonomous moving body and is different from the autonomous moving body among the plurality of moving bodies and which is the priority / subordination degree having been sent to the autonomous moving body by the movement managing section, and a self priority/subordination degree, which is the priority/subordination degree determined by the priority/subordination determining section for the autonomous moving body and having been sent to of the autonomous moving body by the movement managing section, or a priority/subordination receiving section configured to receive from the movement managing section a comparison result between the another priority/subordination degree and the self priority/subordination degree acquired through a comparison made by the movement managing section, the movement managing section further includes a priority/subordination adjusting section configured to adjust the priority/subordination degree when there are a plurality of moving bodies that have equal priority/subordination degrees, when there are a plurality of moving bodies that have equal priority/subordination degrees, the priority/subordination adjusting section adjusts the priority/subordination degree of a moving body for which a timing at which the priority/subordination degree was determined is a first timing to become higher than the priority/subordination degree of a moving body for which a timing at which the priority/subordination degree was determined is a second timing that is later than the first timing.
