PROBLEM TO BE SOLVED: To preferably change area distribution to a plurality of mobile objects to make a task be continued even when mission maintenance becomes difficult due to various mission inhibition factors in the plurality of mobile objects for performing a prescribed mission in an individual area.;SOLUTION: An operation control system 10 controls operation of a plurality of unmanned aircrafts 1 for performing a monitoring mission individually in a plurality of monitoring airspace WA adjacent to each other. A controller 23 of a ground station 2 acquires enclosure information on each unmanned aircraft 1 to determine whether a plurality of unmanned aircrafts 1 can maintain mission or not based on the information. When there is the unmanned aircraft 1 that is difficult to maintain the mission, a plurality of airspace division patterns P are set that are redivided by matching a portion where the unmanned aircraft 1 can fly in the plurality of monitoring airspace WA with an aircraft that can maintain the mission among the plurality of unmanned aircrafts 1, an evaluation value concerning a mission inhibition degree is calculated on each of the air space division patterns P on the basis of the enclosure information, and a pattern with the lowest mission inhibition degree among the plurality of air space division patterns P is selected based on the evaluation value.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2019,JPO&INPIT
