Abstract

A computer implemented method and computer system for management of materials on a construction site. In one embodiment, at least one cost scenario is defined for moving at least one material with a vehicle pool. A status of a project which uses the material is then determined. A report is generated which identifies a vehicle of the vehicle pool and defines a load of the material which is to be moved by the vehicle from a first location to a second location.

Claims

1. A computer implemented method for management of materials on a construction site, said method comprising:

defining at least one cost scenario to move at least one material with a vehicle pool;

determining a status of a project which uses the at least one material; and

generating a report which identifies a vehicle of said vehicle pool and defines a load of the material which is to be moved by said vehicle from a first location to a second location.

2. The method as recited in claim 1 wherein said defining further comprises:

defining the cost to move the material from said first location to said second location using said vehicle pool.

3. The method as recited in claim 2 further comprising:

determining at least one variable of the material which affects said cost scenario.

4. The method as recited in claim 3 further comprising:

determining the moisture content of the material.

5. The method as recited in claim 2 further comprising:

defining at least one site variable selected from the group consisting of a distance to move the material from said first location to said second location, a road condition between said first location and said second location, how fast the material can be moved from said first location to said second location, a time when the material is moved from said first location to said second location, and a weather variable.

6. The method as recited in claim 2 further comprising:

receiving an indication of a weighted value which is used to assign said load of the material to said vehicle and wherein said weighted value is selected from the group consisting of;

minimizing the cost to move the material from said first location to said second location and the maximizing the volume of the material which can be moved from said first location to said second location.

7. The method as recited in claim 2 further comprising:

receiving an indication selected from the group consisting of the availability of an operator for said vehicle and the productivity of said operator of said vehicle.

8. The method as recited in claim 1 wherein said vehicle pool comprises a plurality of vehicles, said method further comprising:

determining which of said plurality of vehicles are available; and

generating a plurality of reports which define how the material is to be moved by said vehicle pool.

9. The method as recited in claim 8 further comprising:

identifying at least one additional vehicle which can be included in said vehicle pool from an outside site.

10. The method as recited in claim 1 further comprising:

conveying a machine work flow plan wirelessly to said vehicle.

11. The method as recited in claim 1 further comprising:

generating at least one simulation which models each movement of the material based upon the current status of the site and a desired status of the site.

12. The method as recited in claim 1 wherein said generating said report further comprises:

defining a route for said vehicle to use.

13. A computer implemented system for managing an asset on a construction site, said system comprising:

a cost scenario generator configured to define at least one cost scenario to move a material with a vehicle pool;

a status determiner configured to determine the status of a project which uses the material; and

a report generator configured to generate a report which identifies a vehicle of said vehicle pool and defines which load of the material is to be moved by said vehicle from a first location to a second location.

14. The system of claim 13 wherein said cost scenario generator is further configured to define the cost to move the material from said first location to said second location using said vehicle pool.

15. The system of claim 14 wherein said cost scenario generator is further configured to receive at least one variable of the material which affects said cost scenario.

16. The system of claim 15 further comprising a moisture content estimator configured to generate an estimate of the moisture content of the material.

17. The system of claim 13 wherein said status determiner is further configured to receive at least one site variable selected from the group consisting of a distance to move the material from said first location to said second location, a road condition between said first location and said second location, how fast the material can be moved from said first location to said second location, a time when the material is moved from said first location to said second location, and a weather variable.

18. The system of claim 13 wherein said report generator is further configured to receive an indication of a weighted value which is used to assign said load of the material to said vehicle and wherein said weighted value is selected from the group consisting of:

minimizing the cost to move the material from said first location to said second location and the maximizing the volume of the material which can be moved from said first location to said second location.

19. The system of claim 13 wherein said status determiner is further configured to receive an indication selected from the group consisting of the availability of an operator for said vehicle and the productivity of said operator of said vehicle.

20. The system of claim 13 wherein said cost scenario generator is further configured to receive an indication of a plurality of vehicles comprising said vehicle pool which are available;

and

wherein said report generator is configured to generate a plurality of reports which define how the material is to be moved by said vehicle pool.

21. The system of claim 20 wherein said report genitor is further configured to define a route to be used by said vehicle when moving a load of the material from said first location to said second location and to define a route to be used by said vehicle when returning from said second location to said first location.

22. The system of claim 20 wherein said cost scenario generator is further configured to receive and indication of at least one additional vehicle which can be included in said vehicle pool from an outside site.

23. The system of claim 13 further comprising:

a wireless transmitter configured to convey a machine work flow plan wirelessly to said vehicle.

24. The system of claim 13 further comprising:

a simulator configured to generate at least one simulation which models each movement of the material based upon the current status of the site and a desired status of the site.

25. A computer implemented method for asset management of a material on a construction site, said method comprising:

defining the cost to move a material from a first location to a second location based upon the availability of a plurality of vehicles of a vehicle pool;

identifying said first location of the material and said second location of the material based upon a current status of said project and a desired status of said project; and

generating a report which defines a load of the material and a vehicle of said plurality of vehicles which is used to move said load of the material from said first location to said second location.

26. The method as recited in claim 25 further comprising:

conveying a machine work flow plan wirelessly to said vehicle which identifies said first location, said second location, and said load of the material.

27. The method as recited in claim 26 further comprising:

conveying a route to use when moving said load of the material.

28. The method as recited in claim 25 further comprising:

determining the moisture content of the material.
