Claims
- 1. A production planning system, comprising:
a graphical user interface configured to receive values for one or more capacity attributes characterizing a manufacturing line configured to produce one or more products, and to display one or more inventory investment amounts computed based upon the received capacity attribute values and needed to cover expected demand and expected demand uncertainty for the one or more products over an exposure period with a target service level.
- 2. The system of claim 1, wherein the graphical user interface includes a capacity attributes section prompting a user to input values for one or more of the following capacity attributes characterizing the manufacturing line: shift length; number of shifts in a given unit of time; mean time line is inoperable; mean set-up time; set-up time variability; and production scheduling variability.
- 3. The system of claim 1, wherein the graphical user interface is configured to receive values for one or more production attributes characterizing the one or more products.
- 4. The system of claim 3, wherein the graphical user interface includes a production attributes section prompting a user to input values for one or more of the following production attributes for each of the one or more products: mean demand; demand uncertainty; line cycle time; and average time between builds.
- 5. The system of claim 1, wherein the graphical user interface includes a total inventory investment section for displaying a total inventory investment amount needed to cover expected demand and expected demand uncertainty for all of the products over an exposure period with a target service level.
- 6. The system of claim 1, wherein the graphical user interface includes a product-specific inventory investment section for displaying a respective inventory investment amount needed to cover expected demand and expected demand uncertainty for each of the products over an exposure period with a target service level.
- 7. The system of claim 1, wherein the graphical user interface is configured to display one or more computed manufacturing capacity levels needed to cover expected demand and expected demand uncertainty for the one or more products over an exposure period with a target service level.
- 8. The system of claim 7, wherein the graphical user interface includes a total manufacturing line capacity section for displaying one or more measures of total line utilization needed to cover expected demand and expected demand uncertainty for all of the products over an exposure period with a target service level.
- 9. The system of claim 7, wherein the graphical user interface includes a product-specific manufacturing line capacity section for displaying a respective measure of manufacturing line responsiveness for each of the products.
- 10. The system of claim 1, wherein the graphical user interface is configured to display a graph of total production cost plotted as a function of excess manufacturing line capacity.
- 11. A production planning method, comprising:
receiving values for one or more capacity attributes characterizing a manufacturing line configured to produce one or more products; and displaying one or more inventory investment amounts computed based upon the received capacity attribute values and needed to cover expected demand and expected demand uncertainty for the one or more products over an exposure period with a target service level.
- 12. The method of claim 11, further comprising prompting a user to input values for one or more of the following capacity attributes characterizing the manufacturing line: shift length; number of shifts in a given unit of time; mean time line is inoperable; mean set-up time; set-up time variability; and production scheduling variability.
- 13. The method of claim 11, further comprising receiving values for one or more production attributes characterizing the one or more products.
- 14. The method of claim 13, further comprising prompting a user to input values for one or more of the following production attributes for each of the one or more products: mean demand; demand uncertainty; line cycle time; and average time between builds.
- 15. The method of claim 11, further comprising displaying a total inventory investment amount needed to cover expected demand and expected demand uncertainty for all of the products over an exposure period with a target service level.
- 16. The method of claim 11, further comprising displaying a respective inventory investment amount needed to cover expected demand and expected demand uncertainty for each of the products over an exposure period with a target service level.
- 17. The method of claim 11, further comprising displaying one or more computed manufacturing capacity levels needed to cover expected demand and expected demand uncertainty for the one or more products over an exposure period with a target service level.
- 18. The method of claim 17, further comprising displaying one or more measures of total line utilization needed to cover expected demand and expected demand uncertainty for all of the products over an exposure period with a target service level.
- 19. The method of claim 17, further comprising displaying a respective measure of manufacturing line responsiveness for each of the products.
- 20. The method of claim 11, further comprising displaying a graph of total production cost plotted as a function of excess manufacturing line capacity.
