Performance-based haulage management system
First Claim
1. A method for managing haul routes in work environments, comprising:
- collecting performance data associated with a machine during a haul route run in a work environment;
monitoring a route completion time associated with the machine;
comparing the route completion time with a threshold completion time;
selecting, if the route completion time exceeds the threshold completion time, a first payload level for the machine;
simulating operation of the machine based on the first payload level to generate a simulated route completion time of the machine; and
establishing a payload limit of the machine as the first payload level if the simulated route completion time does not exceed the threshold completion time.

Abstract
A method for managing haul routes in work environments comprises collecting performance data associated with a machine operating in a work environment. The method also includes determining a drive axle torque of the machine and estimating a total effective grade associated with the machine based on the drive axle torque. The estimated total effective grade is compared with a threshold level and, if the estimated total effective grade exceeds the threshold level, a design performance of the machine may be simulated based on the calculated total effective grade. Design performance data is compared with the collected performance data, and a payload limit of the machine is adjusted if the design performance is inconsistent with collected performance data.
