摘要： Methods and systems of directing the movement of a plurality of batch delivery systems between a loading area and a continuous material processor determine a location of each of at least two of the plurality of batch delivery systems; determine a state of each of the located batch delivery systems; predict an estimated time of arrival at the continuous material processor of a loaded batch delivery system in transit from the loading area to the continuous material processor; predict a number of loaded batch delivery systems that will be located at the continuous material processor at a future time; estimate an idle time for the predicted number of loaded batch delivery systems at the continuous material processor; predict a time when the continuous material processor will be in a No-Material state; and direct the movement of at least one of the plurality of batch delivery systems to minimize at least one of the estimated idle time and the time when the continuous material processor will be in the No-Material state.

摘要： Methods of deploying shovels and haul trucks to meet a defined production target may include: Determining at least one production constraint for a shovel and a material processing system; estimating an effect of entropy on a cycle time of the haul trucks to produce a future cycle time estimate; estimating an effect of entropy on a material processing time of the material processing system to produce a future material processing time estimate; predicting whether a delay will occur during the operation of the shovel, the haul trucks, and the material processing system; estimating a duration of the predicted delay; determining a number of shovels and a number of haul trucks required to meet the defined production target based on the determined production constraint, the future cycle time estimate, the future material processing time estimate, and the duration of the predicted delay; and deploying the determined number of shovels and the determined number of haul trucks.

摘要： Systems and methods of operating vehicles to reduce bunching of the vehicles when traveling on a roadway determine an intra arrival time for two consecutive vehicles traveling on the roadway; calculate a virtual spacing between the two consecutive vehicles based on the intra arrival time; determine a following distance threshold; compare the virtual spacing between the two consecutive vehicles with the following distance threshold; determine that the two consecutive vehicles are in a bunched condition when the virtual spacing between the two consecutive vehicles is less than the following distance threshold; and control at least one of the two consecutive vehicles until the vehicles are no longer in the bunched condition.

摘要： Methods and systems of determining and controlling a vehicle travel speed on a roadway determine a grade of the roadway at defined intervals along the roadway; calculate a maximum straight line vehicle speed for each defined interval based on the determined grade and vehicle performance data; determine a radius of curvature and a superelevation of the roadway for each defined interval; determine a lateral friction coefficient for a vehicle/roadway system; calculate a maximum cornering vehicle speed for each defined interval based on the curvature, superelevation, and lateral friction coefficient; calculate the travel speed for each defined interval based on the maximum straight line vehicle speed and the maximum cornering vehicle speed; and control the speed of the vehicle so that it does not exceed the calculated travel speed for each defined interval.

摘要： A system for optimizing a travel speed of an off-road vehicle utilizes time-over-target values as a threshold indicator for diagnostics and subsequent remedial actions. A road used for haulage is divided into a plurality of predetermined road segments. A target transit time is defined for each of the predetermined segments to provide a target speed curve. An actual transit time values is measured for the off-road vehicle in transiting the road. A comparison outcome is generated by comparing the target transit time value with the actual transit time value. The comparison outcome is useful in diagnosing causes of operation trouble and in scheduling remedial action to address the operational trouble.
