Abstract

A testing system configured to test a person'"'"'s performance at manufacturing related tasks comprises at least one simulated workstation in one embodiment. Each simulated workstation is modeled after a manufacturing related task and comprises at least one work piece to which the task is to be conducted, and at least one detector associated with the work piece. The detector is operable to detect a manufacturing task performed by a person and is configured to generate a signal based upon on the performance. The simulated workstation further comprises at least one instructional device configured to inform a person of the tasks to be performed on the work piece at the workstation, and at least one automated electronic scoring mechanism configured to receive the signal from the detector and tabulate a person'"'"'s performance at the task.

Claims

1. A testing system configured to test a person'"'"'s performance at manufacturing related tasks, comprising:

at least one simulated workstation, wherein the workstation models a manufacturing related task and comprises,

at least one work piece to which the task is to be conducted;

at least one detector associated with the work piece, the detector operable to detect a manufacturing task performed by a person and configured to generate a signal based upon the performance;

at least one instructional device configured to inform a person of the tasks to be performed on the work piece at the workstation; and

at least one automated electronic scoring mechanism configured to receive the signal from the detector and tabulate a person'"'"'s performance at the task.

2. A system according to claim 1 wherein the simulated workstations are configured to test a person'"'"'s performance at bolt insertion and removal, at wire harness connection and disconnection, at welding, at painting, at handling weights of various sizes, or combinations thereof.

3. A system according to claim 1 wherein the instructional device comprises a display monitor, an audio device, an instruction document, or combinations thereof.

4. A system according to claim 1 wherein the testing system further comprises a user control component configured to allow a person to control the instructional device, and comprising a keypad, a mouse, or combinations thereof.

5. A system according to claim 1 wherein the detector comprises an imaging device configured to provide image data representing the work piece, wherein the image data comprises the signal sent to the automated electronic scoring mechanism.

6. A system according to claim 1 wherein the detector is a sensor comprising a switch configured to open or close a circuit upon actuation, a magnetic switch, a motion sensor, a contact switch, relay, proximity switch, position detector, or combinations thereof.

7. A system according to claim 1 further comprising a signal converter operable to translate the detector signal into a usable format for the automated scoring mechanism.

8. A system according to claim 1 wherein the automated electronic scoring mechanism is configured to record the speed and accuracy of a person performing manufacturing tasks.

9. A system according to claim 1 wherein the automated electronic scoring mechanism is operable to randomize the tasks performed at a simulated workstation.

10. A system according to claim 1 wherein the automated electronic scoring mechanism is operable to score a person'"'"'s performance against at least a sample of all test takers.

11. A system according to claim 1 wherein the automated electronic scoring mechanism is operable to adjust a person'"'"'s score to correct for malfunctions in the simulated work station.

12. A system according to claim 1 wherein the automated electronic scoring mechanism comprises a microprocessor or computer.

13. A system according to claim 1 wherein the automated electronic scoring mechanism comprises software configured to tabulate the scores of the person'"'"'s performance.

14. A work evaluation method comprising:

providing at least one simulated workstation configured to inform one or more persons of a manufacturing task to be performed at the simulated workstation, and to automatically score the person'"'"'s performance at the task;

receiving score data from the simulated workstation on the persons'"'"' performance at the manufacturing task;

producing a work profile for each person from the score data;

providing at least one job profile comprising performance criteria required for a specific job; and

ascertaining whether the person'"'"'s work profile substantially matches the performance criteria of the job profiles.

15. A work evaluation method according to claim 14 further comprising making an offer of employment to those persons whose profiles substantially match the performance criteria.

16. A work evaluation method according to claim 14 further comprising providing a tutorial that demonstrates the proper procedure for performing the manufacturing related tasks.

17. A work evaluation method comprising:

providing a first manufacturing related task to be performed by a person at a simulated workstation;

recording the person'"'"'s performance of the first task at the simulated workstation via an automated electronic scoring mechanism; and

generating automatically at least one additional task to be performed by the person at the simulated workstation based upon the recorded performance of the first task.

18. A work evaluation method according to claim 17 wherein the recording of the performance further comprises the steps of

receiving signals from a plurality of detectors to record the persons, the detectors being triggered by the person performing the manufacturing related task;

and

evaluating the person'"'"'s performance by comparing the timing and order of the detector signals to an expected timing and order of detector signals.

19. A method according to claim 17 wherein the automatically generating operation comprises:

determining the affected location on the workstation of the person'"'"'s performance of the first task; and

determining an additional task to be performed at the workstation, such that the affected location does not preclude completion of the additional task.

20. A method according to claim 17 further comprising assigning at least one additional task at another simulated workstation.
