Systems and methods of automatically scheduling a workforce
View Patent ↗Systems and methods of workforce scheduling are disclosed. One example embodiment, among others, comprises a computer-implemented method of scheduling workers. Each worker is associated with one of a set of flexibility classifications, which include non-flex-time and at least one flex-time. The method includes generating a set of shift instances to cover forecasted demand over a planning period, and assigning the shift instances to the set of workers by iterating through the each of the workers to assign at least a portion of the shift instances to a selected one of the workers. The assigning is such that total hours assigned to the selected worker depends on a number associated with the classification of the selected worker.
1. A system of scheduling a set of workers, each worker associated with one of a set of flexibility classifications, the set including a flex-time classification, comprising:
a processor comprising:
logic configured to generate a set of shift instances to cover forecasted demand over a planning period;
logic configured to produce a set of staff mix enumerations to cover the shift instances, the set of enumerations varying from a first enumeration including zero workers of at least one non-flex-time classification and a first computed number of workers of the flex-time classification, to a last enumeration including a maximum number of workers of the at least one non-flex-time classification and a last computed number of workers of the flex-time classification; and
logic configured to assign the shift instances to the set of workers by iterating through the each of the workers to assign at least a portion of the shift instances to a selected one of the workers, such that total hours assigned to the selected worker depends on a per-interval maximum number and a per-interval minimum number of hours associated with the classification of the selected worker.
2. The system of claim 1 , wherein workers having a classification other than flex-time are assigned shift instances before workers having a classification of flex-time.
3. The system of claim 1 , wherein the total hours assigned to the selected worker approach, but do not exceed, the per-interval maximum associated with the classification of the selected worker.
4. The system of claim 1 , wherein the logic configured to assign uses dynamic programming to assign the shift instances to the set of workers.
5. The system of claim 1 , further comprising logic configured to adjust shift assignments, wherein the logic configured to adjust shift assignments comprises:
logic configured to determine the presence of an unassigned shift instance on a given day;
logic configured to determine the presence of an underutilized worker as compared to the per-interval maximum associated with the classification of the corresponding worker; and
logic configured to assign the unassigned shift instance to the underutilized worker.
6. The system of claim 5 , wherein the logic configured to adjust further comprises:
logic configured to determine the presence of a shift instance assigned to the underutilized worker on the given day; and
logic configured to swap the shift instance assigned to the underutilized worker on the given day with another shift instance assigned to another worker on a different day.
7. The system of claim 1 , further comprising logic configured to adjust shift assignments, performed conditionally based on a number of unassigned shifts, wherein the logic configured to adjust shift assignments comprises:
logic configured to determine the presence of an unassigned shift instance on a given day;
logic configured to determine the presence of an underutilized worker as compared to the per-interval maximum associated with the classification of the corresponding worker; and
logic configured to assign the unassigned shift instance to the underutilized worker.
