The central processing unit is also configured to perform prognostic analysis based on the received use history information and to determine an estimated remaining life for the piece of equipment based on the prognostic analysis. The central processing unit is further configured to generate a report for the piece of equipment based on the prognostic analysis and to provide the generated report to a user. | 01-01-2009 |
| 20090063031 | Performance-based haulage management system - 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. | 03-05-2009 |
| 20090063226 | Systems and methods for improving haul route management - A method for managing haul routes in work environments comprises receiving performance criteria associated with a haul route and establishing a target total effective grade for at least one machine associated with the haul route based on the performance criteria. The method also includes collecting performance data associated with the at least one machine. A drive axle torque of the at least one machine is determined and an actual total effective grade associated with the at least one machine is estimated. The at least one machine is identified as an underperforming machine if the actual total effective grade for the at least one machine exceeds the target total effective grade. An average total effective grade for the at least one machine is determined as a function of the actual total effective grade. A haul route deficiency is identified if the average total effective grade exceeds a threshold level. | 03-05-2009 |
| 20090099707 | Systems and methods for improving haul road conditions - A method for improving haul road surface conditions comprises collecting performance data associated with at least one machine operating on a haul route and determining a rolling resistance of each of the at least one machine based on the performance data. An average rolling resistance associated with one or more portions of the haul route is determined based on the rolling resistance of each of the at least one machine. The one or more portions of the haul route are identified as irregular if the average rolling resistance of the one or more portions exceeds a threshold resistance value. A proposed modification to the irregular portion of the haul route is generated, and performance of the at least one machine is simulated based on the proposed modification. The method also includes outputting results of the simulated performance. | 04-16-2009 |
| 20090099708 | Systems and methods for designing a haul road - A method for designing a haul road based on machine performance comprises receiving one or more haul road parameters and identifying at least one type of machine to be operated on the haul road. The method also includes selecting at least one target operating parameter associated with the at least one type of machine and simulating performance of the at least one type of machine to predict an operating value corresponding with the at least one target operating parameter. If the predicted operating value is not within a threshold range of the corresponding target operating parameter, one or more haul road parameters are adjusted. | 04-16-2009 |
| 20090099886 | System and method for performance-based payload management - A method for managing machine payload based on haul road conditions comprises collecting performance data associated with a machine operating in a work environment and determining an actual total effective grade of the machine based on the collected performance data. The total effective grade is compared with a target total effective grade value, and total effective grade associated with a plurality of payload levels may be simulated if the actual total effective grade is not within a threshold range of the target total effective grade value. At least one of the plurality of payload levels that causes the simulated total effective grade to fall within the threshold range of the target total effective grade value is identified. | 04-16-2009 |
| 20090154992 | Systems and methods for haul road management based on greenhouse gas emissions - A method for haul road design based on greenhouse gas emissions comprises receiving a first set of performance data associated with a plurality of machines and establishing a greenhouse gas emission limit for the plurality of machines based on the first set of performance data. A target greenhouse gas emission level for each of the plurality of machines is determined based on the greenhouse gas emission limit, and total effective grade is determined based on the target greenhouse gas emission level for the respective machine. The method also includes generating a haul road design based on the total effective grade. | 06-18-2009 |
| 20110288908 | SYSTEMS AND METHODS FOR IMPROVING HAUL ROAD CONDITIONS - A method for improving haul road surface conditions comprises collecting performance data associated with at least one machine operating on a haul route and determining a rolling resistance of each of the at least one machine based on the performance data. An average rolling resistance associated with one or more portions of the haul route is determined based on the rolling resistance of each of the at least one machine. The one or more portions of the haul route are identified as irregular if the average rolling resistance of the one or more portions exceeds a threshold resistance value. A proposed modification to the irregular portion of the haul route is generated, and performance of the at least one machine is simulated based on the proposed modification. The method also includes outputting results of the simulated performance. | 11-24-2011 |
