PROBLEM TO BE SOLVED: To provide an operation management system and an operation management method capable of determining where and how much a work apparatus is operating.;SOLUTION: An operation management system comprises a first communication device, a second communication device, and a third communication device capable of communicating with each other. The first communication device includes a first acquisition part for acquiring atmospheric pressure information indicating an atmospheric pressure of a place where works are performed by a work apparatus to be used when constructing a multi-layered structure and operation information indicating whether the work apparatus is operating or not. The second communication device includes a second acquisition part for acquiring reference floor atmospheric pressure information indicating an atmospheric pressure of a reference floor to be a reference in a height direction in the structure. The third communication device includes a control part for determining a work floor indicating where the work apparatus is disposed on the basis of the atmospheric pressure information and the reference floor atmospheric pressure information and for generating a work floor-based operation status table in which the operation information is associated with the work floor.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
