Abstract

A system of tracking objects through a service process at a service shop comprises a computer network configured to track movement of tagged service objects from physical location to physical location within the service shop. The computer network comprises tag readers with antennae configured to receive transmissions from tags encoded with identifiers and connected to associated tagged service objects. The tag readers transmit identifiers obtained from the tag transmissions together with an indication as to which antenna received each transmission. Servers receive the identifiers transmitted from the tag readers and determine, based at least on the identifiers and which tag reader antenna received the transmissions, which physical location each service object associated with the received identifiers occupies. Client workstations generate a visual map of physical locations together with summary status information showing which service objects occupy the displayed physical locations.

3. The service shop of claim 2, further comprising a tagging area configured as a place for the connection of a tag to a service object in order to create a tagged service object, the tagging area having one or more tag writer workstations for encoding an identifier onto each tag.

4. The service shop of claim 2, wherein the service shop comprises an automobile service shop and the service objects comprise automobiles.

5. The service shop of claim 2, wherein the computer network is further configured to associate with each service object one of a plurality of service processes, each service process defining an ordered list of one or more service steps to be performed to a service object and one or more physical locations to be visited for the performance of the service steps, the servers are further configured to maintain information sufficient to forecast future physical locations expected to be visited by each service object based at least in part on the service object'"'"'s associated service process, and the client workstations are further configured to display at least one report that forecasts future physical locations expected to be visited by a selected service object.

6. The service shop of claim 5, wherein the servers are further configured to forecast, in addition to future physical locations to be visited, an estimated time of completion of the service process associated with each service object, the estimated time of completion derived at least partially from projected availability of physical locations defined as part of each service object'"'"'s service process.

7. The service shop of claim 2, wherein the tag readers are configured to receive transmissions using radio frequency transmissions from the tags which comprise radio frequency identification tags.

8. A computer readable storage medium comprising a substrate configured to encode computer executable instructions, the computer executable instructions being configured, when executed on one or more computers, to perform the following:

track movement of tagged service objects from physical location to physical location, each physical location being one of a plurality of physical locations and configured as a place for the performance of at least one service on a service object;

receive identifiers and source information from one or more radio frequency identification receivers configured to receive transmissions from tags each encoded with an identifier and connected to an associated tagged service object, the source information configured to identify which receiver received each identifier;

determine, based at least on the identifiers and which receivers received the transmissions, which physical location each service object associated with the received identifiers occupies, and to maintain information sufficient to generate a report showing at least any past physical locations visited by each service object and a current physical location occupied by each service object; and

generate from the maintained information at least a visual map depicting a graphical representation displaying at least some of the physical locations together with summary status information showing which service objects occupy the displayed physical locations.

9. The computer readable storage medium of claim 8, wherein the computer executable instructions are further configured, when executed by a computer, to generate at least one of a first report, a second report, or a third report, wherein:

the first report displays at least, for one or more of the physical locations, statistics regarding how many service objects have entered each physical location during a specified time period, an aggregate time that the service objects have been in each physical location, and an average time spent per service object per physical location;

the second report displays at least, for each of a plurality of service objects, an identifier associated with the service object, an arrival date for the service object at a service shop, and a departure date for the service object at the service shop; and

the third report displays at least a plurality of delays that occurred at a service shop during a specified date range, each physical location at which each delay occurred, an identifier associated with each service object for which each delay occurred, and a date and time of each delay.

10. The computer readable storage medium of claim 8, wherein the computer executable instructions are further configured, when executed by a computer, to identify circumstances in which the received identifiers and source information lead to ambiguity in a determination regarding which physical location a particular service object occupies, and to resolve such ambiguity by performing a potential fields calculation to determine which physical location the particular service object most likely occupies.

11. The computer readable storage medium of claim 8, wherein the computer executable instructions are further configured, when executed by a computer, to associate with each service object one of a plurality of service processes, each service process defining an ordered list of one or more service steps to be performed to a service object and one or more physical locations to be visited for the performance of the service steps, to maintain information sufficient to forecast future physical locations expected to be visited by each service object based at least in part on the service object'"'"'s associated service process, and to display at least one report that forecasts future physical locations expected to be visited by a selected service object.

12. The computer readable storage medium of claim 11, wherein the computer executable instructions are further configured, when executed by a computer, to forecast, in addition to future physical locations to be visited, an estimated time of completion of the service process associated with each service object, the estimated time of completion derived at least partially from projected availability of physical locations defined as part of each service object'"'"'s service process.

13. The computer readable storage medium of claim 12, wherein the projected availability of a particular physical location for a particular service object is derived at least in part from a determination of how many other service objects are projected to visit the particular physical location prior to a projected visit of the particular service object to the particular physical location and an estimated time for each visit by the other service objects to the particular physical location.

14. A method of tracking service objects through a service process, the method comprising:

receiving a plurality of service objects to be serviced;
