Work Center Maintenance Screen
Work Center can be regarded as a single machine, multiple machines that are similar or a work place, like a workbench, shipping area, a CNC machine or assembly line. Each work center carries its own burden setup, so the system will calculate burden cost based on these values for production at this work center. Also, the way to operate the machine is defined through the Machine Hour Calculation Method.
Entry Field Descriptions
Name | Type and Description |
1. Work Center ID | 6 alpha-numeric characters. Work Center ID. |
2. Description | 30 alpha-numeric characters. Description of this work center. |
3. Department | 4 alpha-numeric characters. Can be blank. Multiple work centers can belong to one department. By assigning a department ID, it is possible to evaluate the performance of work centers and summarize the evaluation for the department. If department ID is given, most of the following fields default to values in the department file. |
4. Labor Absorb Account | Default Account format. Labor Absorb Account for this work center. Different labor absorb accounts can be defined for different work centers. Defaults to BOMP Global Setup or Department file. |
5. Burden Absorb Account | Default Account format. Burden Absorb Account for this work center. Different burden absorb accounts can be defined for different work centers. Defaults to BOMP Global Setup or Department file. |
6. Def Direct Labor Grade | 2 alpha-numeric characters. Default labor grade for direct labor at this work center. Any operation in this work center will default to this labor grade in the operation file. Defaults to BOMP Global Setup or Department file. |
7. Def Shared Labor Grade | 2 alpha-numeric characters. Default labor grade for shared labor at this work center. Any operation in this work center will default to this labor grade in the operation file. Defaults to BOMP Global Setup or Department file. |
8. Substitute Work Center | 6 alpha-numeric characters. The substitute for this work center. If there is more than one similar work center function and it is possible to change the production routing from one to another, this field defines the substitute for this work center. The operator can change the production to this work center in certain situations. |
9. No of Machines | 2 numeric digits. Number of machines in the work center. One work center can represent more than one machine. This field indicates how many machines are in this work center and the system will give a warning if an operator tries to report work on more machines than the capacity. 0 - This work center has no machines or the capacity should be bypassed. The default is 0. |
10. Machine Hour Calculation Method | 1 alpha-numeric character. “M”, “C” or “S” This field indicates how the machine is operated and so defines how the machine hours will be collected for production at this work center. Options M - All crew members are operating the same machine at one time. A Machine Hour is equal to the hours the crew spends on it. (Machine Hours = Labor Hours) C - Each crew member is operating their own machine. A Machine Hour is the sum of the hours that each member spends on it. (Machine Hours = Labor Hours times Number Of Crew Members) S - There is no direct relationship between Labor Hours and Machine Hours. This may be a situation where the machine can run independently without an operator involved, like a Computer Numerical Controlled (CNC) Machine. Defaults to BOMP Global Setup or Department file. |
End By Def If Labor End | “Y” or “N” This determines the default of whether a machine will continue or be suspended when an operator leaves it if the Machine Calculation Method is “S”. The operator can override this during production. Defaults to BOMP Global Setup or Department file. |
11. Pct / Labor Amount | 10 numeric digits with 6 decimal places and an optional minus sign. Normal Burden from percentage of Labor Amount. |
12. Pct / Material Amt | 10 numeric digits with 6 decimal places and an optional minus sign. Normal Burden from percentage of Material Amount. |
13. Amt / Unit Weight | 12 numeric digits with 6 decimal places and an optional minus sign. Normal Burden from per unit of parent item weight. |
14. Amt / Unit Volume | 12 numeric digits with 6 decimal places and an optional minus sign. Normal Burden from per unit of parent item volume. |
15. Amt / Prod Qty | 12 numeric digits with 6 decimal places and an optional minus sign. Normal Burden from per piece processed in production. |
16. Amt / Dirc Lab Hr | 12 numeric digits with 6 decimal places and an optional minus sign. Normal Burden from per hour of Direct Labor. |
17. Amt / Shar Lab Hr | 12 numeric digits with 6 decimal places and an optional minus sign. Normal Burden from per hour of Shared Labor. |
18. Amt / Machine Hr | 12 numeric digits with 6 decimal places and an optional minus sign. Normal Burden from per Machine Hour. |
19. Pct / Labor Amount | 10 numeric digits with 6 decimal places and an optional minus sign. Burden in Setup Mode from percentage of Labor Amount. |
20. Pct / Material Amt | 10 numeric digits with 6 decimal places and an optional minus sign. Burden in Setup Mode from percentage of Material Amount. |
21. Amt / Unit Weight | 12 numeric digits with 6 decimal places and an optional minus sign. Burden in Setup Mode from per unit of parent item weight. |
22. Amt / Unit Volume | 12 numeric digits with 6 decimal places and an optional minus sign. Burden in Setup Mode from per unit of parent item volume. |
23. Amt / Prod Qty | 12 numeric digits with 6 decimal places and an optional minus sign. Burden in Setup Mode from per piece processed in production. |
24. Amt / Dirc Lab Hr | 12 numeric digits with 6 decimal places and an optional minus sign. Burden in Setup Mode from per hour of Direct Labor. |
25. Amt / Shar Lab Hr | 12 numeric digits with 6 decimal places and an optional minus sign. Burden in Setup Mode from per hour of Shared Labor. |
26. Amt / Machine Hr | 12 numeric digits with 6 decimal places and an optional minus sign. Burden in Setup Mode from per Machine Hour. |
These parameters allow the operator to configure burden driven by different reasons, either when a machine is operating normally or when a machine is in setup mode. There are two sets of burden parameters for each work center, one for the machine in setup mode and another for normal mode.
Setting these parameters to accurate values requires experience. However, a quick suggestion is to compare the overhead amount each month with information accessible at the time, like the labor dollar amount of that month, labor hours or machine hours. They initially can be reasonable estimates and tuned over time to provide a better estimate for production burden cost.
Based on figure 14, in normal mode, each processed parent item would cost $1 and each machine hour used to produce it will cost $1. So if 10 pieces were produced and the process time at this work center was 2 hours, the burden cost would be $12 ($1 x 10 + $1 x 2).
