Abstract

A method for optimizing a workforce. The method includes the steps of: (A) querying a pool of workers to determine a first set of workers qualified to perform a particular task at a particular time, (B) querying the pool of workers to determine a second set of workers that are present to work at the particular time, (C) querying the pool of workers to determine a third set of workers that have not already been assigned a task at the particular time and (D) determining a fourth set of workers to perform the task at the particular time by selecting workers belonging to each of the first set, the second set, and the third set.

Claims

1. A method for optimizing a workforce by executing a computer program configured to cause a computer to perform a process comprising the steps of:

(A) querying one or more databases, said one or more databases storing, in a non-transitory computer readable medium, information related to a plurality of workers, to determine a first set of workers, each worker in said first set of workers being qualified to perform at least one task from a set of predetermined tasks associated with operation of a production line at a particular time to produce a product;

(B) querying said one or more databases to determine a second set of workers that are available to work on said production line at said particular time, wherein determining the second set of workers includes determining whether a worker will be present at said particular time using an expected arrival time for said worker to arrive at a location where a particular task is to be performed based upon an estimate called in by said worker and historical data regarding accuracy of previous estimates from said worker;

(C) querying said one or more databases to determine a third set of workers that have not already been assigned to a task at said particular time;

(D) determining, by the computer, a fourth set of workers to perform said set of predetermined tasks associated with operation of said production line at said particular time by selecting workers belonging to said first set, said second set, and said third set;

(E) assigning, by the computer, each worker in said fourth set of workers to a respective position on said production line associated with one of said tasks in said set of predetermined tasks associated with operation of said production line, wherein (i) in a first mode, said fourth set of workers are automatically assigned to the respective positions, taking into account said expected arrival times of one or more workers to minimize a total delay associated with starting up said production line by avoiding assignment of a high-skill worker to a low skill job when a low-skill worker is expected to be present, (ii) in a second mode, a report is displayed to a supervisor and the supervisor assigns each worker to the respective position, and (iii) one or more workers can be re-assigned to different positions and associated tasks on said production line during performance of the associated tasks in order to improve a match between skills of said one or more workers and the tasks associated with the one or more positions; and

(F) generating one or more reports for presentation to the supervisor or a manager, said one or more reports containing information about one or more of assignments, replacements, critical positions, absent stations, quality training, overtime equalization, identification of one or more of stations for which more operators should be trained, and operators who could be cross trained.

2. The method according to claim 1, wherein steps (A), (B) and (C) are performed simultaneously.

3. The method according to claim 1, wherein said particular time comprises a particular shift at a factory or manufacturing facility at which said production line is located.

4. The method according to claim 3, wherein step (B) comprises determining availability of said second set of workers a predetermined amount of time before a start of said particular shift.

5. The method according to claim 4, wherein said predetermined amount of time is between 1 and 30 minutes.

6. A non-transitory computer readable medium storing computer readable instructions that when executed cause a computer to execute the steps of claim 1.

7. The method according to claim 1, wherein the process further comprises the step of:

(G) re-assigning at least one worker from a particular station along said production line to which the worker is assigned to another station along said production line as additional workers become available based upon predetermined qualifications of said additional workers and one or more predetermined parameters of said set of predetermined tasks, wherein said at least one worker is re-assigned prior to or during performance of the task associated with the particular station and a number of open positions associated with said production line is reduced.

19. The method according to claim 1, wherein calling in said estimate by said worker is implemented using one or more of a cellular telephone, a pager, a global positioning system (GPS) device, and electronic mail.

8. A non-transitory computer readable medium having computer executable instructions for causing a computer to execute a method for managing a work force comprising the steps of:

determining workers available to perform a plurality of predetermined tasks associated with a plurality of stations of a production line, wherein determining whether a worker is available includes determining whether a worker will be present at a particular time using an expected arrival time for said worker to arrive at a location where a particular task is to be performed based upon an estimate called in by said worker and historical data regarding accuracy of previous estimates from said worker;

automatically assigning each worker who is available to a particular station of said production line based on predetermined qualifications of each worker and one or more predetermined parameters of said plurality of predetermined tasks, wherein said expected arrival time of one or more workers is taken into account to minimize a total delay associated with starting up said production line by avoiding assignment of a high-skill worker to a low skill job when a low-skill worker is expected to be present; and

automatically re-assigning at least one worker from the particular station to which the worker is assigned to another of said plurality of stations as additional workers become available based upon said predetermined qualifications of said at least one worker and said one or more predetermined parameters of the tasks associated with the other stations, wherein said at least one worker is re-assigned prior to or during performance of the task associated with the particular station.

9. The computer readable medium according to claim 8, further comprising a database containing said predetermined qualifications of each of said workers, wherein said predetermined qualifications comprise at least three worker skill levels, a level-3 worker is qualified to do level-1 and level-2 tasks, a level-2 worker is qualified to do level-1 tasks, and assignment of a level-3 worker to a level-1 or level-2 task is delayed if a level-1 or level-2 worker is expected to arrive at a location of said production line within a predetermined time frame based upon said expected arrival time for said level-1 or level-2 worker determined using an estimate called in by said level-1 or level-2 worker.

10. The computer readable medium according to claim 8, wherein said one or more predetermined parameters comprise safety, quality, cost, deliver, morale, defects, repairs, warranty, start-up loss, efficiency loss, productivity, scrap, rework and overmanning.

11. The computer readable medium according to claim 8, further comprising instructions for executing the step of:

operating a remote input device configured to identify workers upon arrival of the workers at a location where said task is to be performed.

12. The computer readable medium according to claim 11, wherein said remote input device is selected from the group consisting of a magnetic card reader, a bio-metric input device, a keyboard, a keypad, and a bar code reader.

13. The computer readable medium according to claim 8, further comprising instructions for executing the step of:

generating reports on assignments and reassignments.

14. The computer readable medium according to claim 8, further comprising instructions for executing the step of:

generating reports identifying one or more of stations for which more operators should be trained and operators who could be cross trained.

15. The computer readable medium according to claim 8, further comprising instructions for executing the steps of:

simulating manning decision outcomes; and

generating forecasts using a forecasting tool, wherein said forecasts predict one or more of quality, flexibility and risk of operation based upon the simulated decisions.

16. The computer readable medium according to claim 8, wherein the step of determining available workers comprises registering an arrival of an employee at a location of a production line for producing a product and the step of automatically assigning each available worker comprises:

checking task and employee databases for placement of the employee whose arrival is registered;

determining whether the employee whose arrival is registered is qualified to perform a predetermined task associated with an open position of said production line;

if the employee whose arrival is registered is qualified, assigning the employee whose arrival is registered to the open position of said production line; and

if the employee whose arrival is registered is not qualified, determining whether a previously assigned employee can be reassigned to the open position or another position of said production line to allow assignment of the employee whose arrival is registered.

17. The computer readable medium according to claim 16, wherein the step of automatically reassigning workers as additional workers arrive comprises:

determining whether another employee can be reassigned from a currently assigned position to an open position to allow assignment of the employee whose arrival is registered, wherein the other employee is re-assigned prior to or during performance of the task associated with the currently assigned position;

if another employee can be reassigned, assigning the employee whose arrival is registered to the currently assigned position and reassigning the other employee to another position such that the number of open positions is reduced;

if another employee cannot be reassigned, determining an impact of the open position on quality and efficiency of an operation of said production line;

if the open position will not have an impact on the quality and efficiency of the operation of said production line, assigning the employee whose arrival was registered to the open position and notifying a manager about the assignment; and
