Abstract

Methods for selecting transportation parameters for transporting parts from at least one point of part supply to at least one point of part demand in a manufacturing facility include determining a physical relationship between the at least one point of part supply and the at least one point of part demand, selecting a transportation route type from a preselected group of transportation route types based at least in part on the physical relationship, selecting an automated guided carrier type from a preselected group of automated guided carrier types based at least in part on the transportation route type, determining a need for traffic control based at least in part on the transportation route type, and if it is determined traffic control is needed, selecting a traffic control type from a preselected group of traffic control types based at least in part on the transportation route type.

Claims

1. A method for selecting transportation parameters for transporting parts from at least one point of part supply to at least one point of part demand in a manufacturing facility, the method comprising:

determining a physical relationship between the at least one point of part supply and the at least one point of part demand;

selecting a transportation route type from a preselected group of transportation route types based at least in part on the physical relationship;

selecting an automated guided carrier type from a preselected group of automated guided carrier types based at least in part on the transportation route type;

determining a need for traffic control based at least in part on the transportation route type; and

if it is determined traffic control is needed, selecting a traffic control type from a preselected group of traffic control types based at least in part on the transportation route type, wherein the transportation route type, the automated guided carrier type and the traffic control type are implemented into the manufacturing facility.

2. The method of claim 1 wherein the at least one point of part supply comprises a first point of part supply that supplies a plurality of first parts and a plurality of second parts.

3. The method of claim 2 wherein the at least one point of part demand comprises a first point of part demand that demands the plurality of first parts and a second point of part demand that demands the plurality of second parts.

4. The method of claim 3 wherein selecting the transportation route type from the preselected group of transportation route types comprises selecting a multi-loop route that connects the first point of part supply to both the first point of part demand and the second point of part demand.

5. A method for selecting transportation parameters for transporting parts from at least one point of part supply to at least one point of part demand in a manufacturing facility, the method comprising:

determining a physical relationship between the at least one point of part supply and the at least one point of part demand;

selecting a transportation route type from a preselected group of transportation route types based at least in part on the physical relationship;

selecting an automated guided carrier type from a preselected group of automated guided carrier types based at least in part on the transportation route type;

determining a need for traffic control based at least in part on the transportation route type; and

implementing the transportation route type and the automated guided carrier type into the manufacturing facility.

6. The method of claim 5 wherein selecting the automated guided carrier type from the preselected group of automated guided carrier types is further based at least in part on part types.

7. The method of claim 5 wherein when the transportation route type comprises an elevated route type, the selected automated guided carrier type comprises an overhead traverser.

8. The method of claim 5 wherein when the transportation route type comprises a long route type, the selected automated guided carrier type comprises an autoguide tugger.

9. The method of claim 5 wherein determining the need for traffic control is further based at least in part on the automated guided carrier type.

10. A method for selecting transportation parameters for transporting parts from at least one point of part supply to at least one point of part demand in a manufacturing facility, the method comprising:

determining a physical relationship between the at least one point of part supply and the at least one point of part demand;

selecting a transportation route type from a preselected group of transportation route types based on the physical relationship;

selecting an automated guided carrier type from a preselected group of automated guided carrier types based at least in part on the transportation route type;

determining a need for traffic control based at least in part on the transportation route type and the automated guided carrier type, wherein if it is determined that traffic control is needed, selecting a traffic control type from a preselected group of traffic control types based at least in part on the transportation route type;

selecting a traffic monitoring protocol based at least in part on the transportation route type; and

implementing the transportation route type, the automated guided carrier type, the traffic control type, and the traffic monitoring protocol into the manufacturing facility.

11. The method of claim 10 further comprising establishing a pull signal protocol for sending the automated guided carrier type only when parts are demanded by any of the at least one point of part demand.

12. The method of claim 10 wherein when the transportation route type does not possess a single line of sight, the selected traffic monitoring protocol comprises monitoring a fault signal using a programmable logic controller or computer on the automated guided carrier type.

13. The method of claim 12 wherein the traffic monitoring protocol comprises determining if a location of the fault signal is close to the at least one point of part supply or the at least one point of part demand.

14. The method of claim 10 wherein if the transportation route type comprises non-orthogonal intersections, then the need for traffic control is determined positive.

15. The method of claim 10 wherein if the transportation route type comprises orthogonal intersections without physical barriers, then the need for traffic control is determined negative.

16. The method of claim 10 wherein selecting the automated guided carrier from the preselected group of automated guided carrier types is further based at least in part on part types.

17. The method of claim 10 wherein the at least one point of part supply comprises a first point of part supply that supplies a plurality of first parts and a plurality of second parts.

18. The method of claim 17 wherein the at least one point of part demand comprises a first point of part demand that demands the plurality of first parts and a second point of part demand that demands the plurality of second parts.

19. The method of claim 18 wherein selecting the transportation route type from the preselected group of transportation route types comprises selecting a multi-loop route that connects the first point of part supply to both the first point of part demand and the second point of part demand.
