A work machine management apparatus includes: a switchback point setting unit configured to set at least one switchback point of a work machine in a work place of a mine; a work point setting unit configured to set a plurality of work points of the work machine; a travel track generating unit configured to generate, based on a position of each of the plurality of work points and a position of the at least one switchback point in a loading place, a plurality of target travel tracks along which the work machine travels in the work place; and a travel track selecting unit configured to select, among the plurality of target travel tracks, a target travel track along which the work machine travels in the work place.

An attachment monitoring system according to an embodiment includes a working machine, attachments, a measurement unit, a terminal device, and a server device. The working machine includes a working arm. Each of the attachments is attached to a leading end part of the working arm so as to be driven by a fluid pressure. The measurement unit is provided to measure at least one of a vibration and the fluid pressure when each of the attachments identified on the basis of individual identifying information is driven. The terminal device is provided in the working machine to acquire measured results of the measurement unit. The server device collects the measured results of the respective attachments from the terminal device, and analyzes operation states of the respective attachments on the basis of the collected measured results.

A method of controlling machines for performing operations at a worksite is disclosed. The method includes receiving pre-construction terrain data, design terrain data, and resource data and then defining a plurality of constraints based on the data. Operations of the machines are simulated based on the data. The method includes estimating process variables associated with the operations and defining and scheduling tasks to be performed by the machines. The method includes collecting real time data from the worksite and updating the estimated process variables and the scheduled tasks of the machines based on the collected real time data. Instructions are then provided to the machines for executing the tasks.

A construction machine management system includes a detection sensor unit installed in a construction machine that is movable in a work site area and a position recognition unit that recognizes position information regarding a position of work executed in the work site area using a movable work tool included in the construction machine based on a detection result obtained by the detection sensor unit with respect to an external indicator installed in the work site area and a detection result obtained by the detection sensor unit with respect to a movable indicator attached to the movable work tool.

A remote server identifies based on unique identification information, model information, operator name information and/or owner name information, and a plurality of pieces of contact information. The remote server identifies trouble content information, estimated cause information, and seriousness information based on trouble content identification information. The remote server simultaneously transmits transmission information to contact addresses indicated by the plurality of pieces of contact information identified, the transmission information including the model information, the operator name information and/or the owner name information, date and time information, position information, the trouble content information, the estimated cause information, and the seriousness information. When the seriousness information has a highest rank, the remote server adds instruction information instructing a phone call to the operator and/or the owner to the transmission information to be transmitted to the contact addresses indicated by the plurality of pieces of contact information.

An operation state management system for a construction machine includes a management apparatus configured to manage an operation state of the construction machine by communicating with the construction machine and a construction machine including a cumulative value storage device configured to store a cumulative value in which an amount of operation of the construction machine is accumulated and have an adjustment function to the stored cumulative value, an adjustment existence determining unit configured to determine whether the cumulative value stored in the cumulative value storage device has been adjusted, and a communication terminal apparatus configured to communicate with the management apparatus and transmit adjustment information indicating that at least the cumulative value has been adjusted to the management apparatus when the adjustment existence determining unit has determined that the adjustment has been performed.
