A system includes a region data module and a planning module. The region data module acquires excavation region data and embankment region data. The excavation region data indicates positions of a plurality of excavation regions at a work site. The embankment region data indicates positions of a plurality of embankment regions at the work site. The planning module determines, as a construction plan, a construction sequence and a target travel path including a combination of a plurality of travel paths connecting the excavation regions and the embankment regions while taking into account a change in a topography at the work site.

System and method for determining construction plan for work machine at construction site

The work state identifying unit identifies a work state of a work machine disposed in a construction site at each time point and a work state of a transport vehicle traveling at the construction site at each time point. The time chart generation unit that generates a time chart representing the work state of the work machine at each time point and a time chart representing the work state of the transport vehicle at each time point on the basis of the identified work states. The output control unit that outputs the time charts on an identical screen with a time axis as a common axis.

Construction site management device, output device, and construction site management method

A work state identifying unit identifies work states of a work machine. A parameter identifying unit identifies a parameter related to a work amount per unit time of the work machine or a parameter related to a speed of the work machine for each of the identified work states on the basis of a time series of position data, azimuth data, or speed data of the work machine.
