1. A moving object operation management device that manages operation of a plurality of moving objects configured to move in a passage provided in an area and perform work at a specific place, the moving object operation management device being configured to,
when the work of a certain moving object hinders movement of another moving object in the passage, set a section including the place where the work is performed as an exclusive section, and
when the exclusive section for one of two moving objects and the exclusive section for the other moving object are adjacent to each other and movement of the one moving object to a next destination by a shortest path is hindered by the exclusive section for the other moving object,
selectively generate a first operation instruction and a second operation instruction by comparing an arrival time of the one moving object at the next destination between the first operation instruction and the second operation instruction, the first operation instruction being an instruction to move the one moving object to the next destination by a path bypassing the exclusive section for the other moving object, and the second operation instruction being an instruction to move the one moving object to the next destination by the shortest path after the exclusive section for the other moving object is cancelled, wherein the second operation instruction is an instruction to, when movement of the other moving object to a next destination by a shortest path is hindered by the exclusive section for the one moving object,
cause the one moving object to retreat into a nearby retreat space so as to cancel the exclusive section for the one moving object,
cause the other moving object to pass through the cancelled exclusive section and move toward the next destination by the shortest path, and then
move the one moving object to the next destination by the shortest path.
