Abstract

A method of displaying a production schedule in three dimensions. Time periods are displayed along an x-axis. Within each time period, an available-capacity rectangle has a width that is all or part of the width of the time period, such that the width represents the proportion of that time period during which capacity is available. Capacity-consuming rectangles are layered on top of the available-capacity rectangles, and include setup rectangles and production rectangles. The width of these rectangles represents the proportion of capacity consumed. The height of production rectangles represents production volume. Cost rectangles may be placed in front of the capacity consuming rectangles, and have a depth that represents relative monetary cost.

Claims

1. A method of providing a three-dimensional display of a production schedule, comprising the steps of:

displaying one or more available-capacity rectangles along a first axis, each having a width along said first axis and a depth along a second axis, each available-capacity rectangle associated with a time period of said production schedule, said width representing available capacity as a proportion of said time period; and

displaying at least one capacity-consuming rectangle atop at least one of said available-capacity rectangles, each capacity-consuming rectangle having three dimensions along said first and second axes and along a third axis, such that the width of each said capacity-consuming rectangle represents capacity consumed in terms of time, and such that said height of each said capacity-consuming rectangle represents production volume.

2. The method of claim 1, wherein said capacity-consuming rectangles comprise setup rectangles, whose widths represent duration of setup times.

3. The method of claim 1, wherein said capacity-consuming rectangles comprise production rectangles whose widths represent duration of production runs.

4. The method of claim 1, wherein said capacity-consuming rectangles comprise setup rectangles, whose widths represent duration of setup times, and wherein said capacity-consuming rectangles further comprise production rectangles, whose widths represent duration of production runs, each said setup rectangle preceding an associated production rectangle.

5. The method of claim 1, further comprising the step of displaying cost rectangles in front of said capacity-consuming rectangles, the depth of each said cost rectangle representing the monetary cost of an associated capacity-consuming rectangle.

6. A computer-implemented production management system, comprising:

a model of a production system;

a scheduling engine operable to generate production schedules to be performed by said production system; and

a presentation interface operable to provide three-dimensional displays representing said production schedules by performing the following steps;

displaying one or more available-capacity rectangles along a first axis, each having a width along said first axis and a depth along a second axis, each available-capacity rectangle associated with a time period of said production schedule, said width representing available capacity as a proportion of said time period; and

displaying at least one capacity-consuming rectangle atop at least one of said available-capacity rectangles, each capacity-consuming rectangle having three dimensions along said first and second axes and along a third axis, such that the width of each said capacity-consuming rectangle represents capacity consumed in terms of time, and such that said height of each said capacity-consuming rectangle represents production volume.

7. The system of claim 6, wherein said capacity-consuming rectangles comprise setup rectangles, whose widths represent duration of setup times.

8. The system of claim 6, wherein said capacity-consuming rectangles comprise production rectangles whose widths represent duration of production runs.

9. The system of claim 6, wherein said capacity-consuming rectangles comprise setup rectangles, whose widths represent duration of setup times, and wherein said capacity-consuming rectangles further comprise production rectangles, whose widths represent duration of production runs, each said setup rectangle preceding an associated production rectangle.

10. The system of claim 6, further comprising the step of displaying cost rectangles in front of said capacity-consuming rectangles, the depth of each said cost rectangle representing the monetary cost of an associated capacity-consuming rectangle.

11. A presentation interface for a computer-implemented production scheduling system, comprising programming media operable to perform at least the following steps when executed by at least one computer processor controlled by data stored in the programming media:

display one or more available-capacity rectangles along a first axis, each having a width along said first axis and a depth along a second axis, each available-capacity rectangle associated with a time period of said production schedule, said width representing available capacity as a proportion of said time period; and

display at least one capacity-consuming rectangle atop at least one of said available-capacity rectangles, each capacity-consuming rectangle having three dimensions along said first and second axes and along a third axis, such that the width of each said capacity-consuming rectangle represents capacity consumed in terms of time, and such that said height of each said capacity-consuming rectangle represents production volume.

12. The programming media of claim 11, wherein said programming is further operable to modify said production schedule in response to manipulation of said rectangles on said display.

13. The programming media of claim 11, wherein said programming is further operable to display production schedule modification options on said display and to modify said production schedule in response to selection of one or more of said options.

14. The programming media of claim 11, wherein said programming media is further operable to display minor setup rectangles and production run rectangles inside said production rectangles.

15. The programming media of claim 11, wherein said programming media is further operable to display segments within said available-capacity rectangles, which represent different types of capacity.

16. A method of providing a three-dimensional display of a production schedule, comprising the steps of:

displaying one or more available capacity-rectangles along a first axis, each having a width along said first axis and a depth along a second axis, each available capacity rectangle associated with a time period of said production schedule, said width representing available capacity as a proportion of said time period;

displaying at least one setup rectangle atop at least one of said available-capacity rectangles, each setup rectangles having a width and a depth, said width representing a duration of that setup; and

displaying at least one production rectangle atop at least one of said available-capacity rectangles, each production rectangle having three dimensions along said first and second axes and along a third axis, such that the width of each said production rectangle represents duration of a production run in terms of time, and such that said height of each said production rectangle represents production volume.

17. The method of claim 16, further comprising the step of displaying cost rectangles in front of said production rectangles, the depth of each said cost rectangle representing the monetary cost of an associated production rectangle.

18. The method of claim 16, further comprising the step of providing a more detailed view of said production rectangles, such that minor setup rectangles within said production rectangles are displayed.

19. The method of claim 16, further comprising the step of providing a more detailed view of said production rectangles, such that items produced within each production rectangle are displayed.
