Abstract

A resource scheduling system includes a set of resources and associated resource attributes, a representation of resource demands, and a scheduling module for generating a schedule of resource utilization. The representation of resource demands and availability may include information about time slots, calendars, and shifts. A slot is a representation of a demand for one or more individual item. A calendar is a representation of dates when resources are needed. Each shift represents a set of time intervals of resource demands. Additionally, the system keeps track of individual resource availability and preferences and attempts to create a resource utilization schedule that satisfies all constraints generated based on the time slots, calendars, shifts, and resource schedules.

Claims

1. A computer-implemented resource scheduling system comprising:

a set of resources and associated attributes;

at least one calendar representing dates for resource utilization;

at least one slot representing demand for one or more individual resource items;

a set of resource constraints generated based on the at least one calendar and the at least one slot; and

a scheduling module for generating a schedule of resource utilization that satisfies at least a subset of the resource constraints.

2. The computer-implemented system of claim 1, further comprising:

at least one shift representing a recurring demand for a pattern of resource allocation.

3. The computer-implemented system of claim 2, wherein the scheduling module assigns individual resources to instances of demand for resources represented by the slots and shifts.

4. The computer-implemented system of claim 1, further comprising:

user interface for generating at least one additional constraint.

5. The computer-implemented system of claim 1, wherein at least one resource of the set of resources has an associated set of time intervals during which said resource is available to be scheduled.

6. The computer-implemented system of claim 1, wherein the scheduling module assigns individual resources to instances of demand for resources represented by the slots.

7. The computer-implemented system of claim 1, wherein the scheduling module generates diagnostic information, and wherein the diagnostic information comprises at least one of the following:

information about conflicts between resource demands, information about resource shortages, information about unavailability of a schedule that satisfies all the resource constraints, information about resource utilization, information about patterns of demand, and information about resource availability.

8. The computer-implemented system of claim 1, further comprising:

an automatic calendar generator that generates a new calendar based on the at least one calendar.

9. The computer-implemented system of claim 1, further comprising:

a user interface for graphically displaying a match between demand for an individual resource and availability of the resource, using rectangular array to display time intervals divided among a plurality of classes.

10. The computer-implemented system of claim 9, wherein the plurality of classes comprise one or more of the following classes:

time intervals for which the resource is both available and in demand, time intervals for which said resource is available and not in demand, and time intervals for which the resource is neither available nor in demand.

11. The computer-implemented system of claim 1, wherein the scheduling module uses constraint propagation for generating the schedule of resource utilization.

12. The computer-implemented system of claim 1, wherein the scheduling module generates a partial schedule satisfying a subset of the resource constraints.

13. A computer-implemented method for resource utilization scheduling, said method comprising:

recording information about a set of resource items;

associating attributes with the set of resource items;

recording demand information about the set of resource items;

generating constraints based on the demand information; and

generating a schedule of resource utilization based on the generated constraints.

14. The computer-implemented method of claim 13, wherein generating constraints based on the demand information further comprises:

providing a user interface for generating constraints.

15. The computer-implemented method of claim 14, wherein providing the user interface for generating constraints further comprises:

describing constraints in a natural language; and

allowing for modification of constraint clauses expressed in the natural language.

16. The computer-implemented method of claim 13, wherein the demand information comprises slot information representing individual resource demands for at least one time slot.

17. The computer-implemented method of claim 13, wherein at least one resource attribute comprises schedule information representing resource demands for a set of time intervals for which an associated resource item is available to be scheduled.

18. The computer-implemented method of claim 13, wherein generating the resource schedule further comprises:

propagating the constraints using constraint back propagation.

19. The computer-implemented method of claim 13, wherein generating the resource schedule further comprises:

generating a list of resource slots; and

assigning the resources to appropriate slots in the list of the resource slots.
