Abstract

A method for allocating system resources includes receiving, by a processor, an assignment list that includes a first assignment and a second assignment, each assignment is assigned a priority and includes tasks associated with each assignment, assigning each assignment to a system resource according to the assigned priority of each assignment, populating a tree for the system resource, the tree including each assignment assigned to the system resource ordered by the relative priority of the assignments, generating task roots associated with each task associated with each assignment in the tree, associating each task root with a task score, defining a first system resource root that includes the task roots having the lowest task scores, calculating a first system resource root score as a function of the task scores of the first system resource root, and saving the first system resource root as the current best estimate system resource root.

generating task roots associated with each task associated with each assignment in the decision tree;

associating each task root with a task score;

defining a first system resource root that includes the task roots having the lowest task scores;

calculating a first system resource root score as a function of the task scores of the first system resource root; and

saving the first system resource root as the current best estimate system resource root.

2. The method of claim 1, wherein the method further comprises:

following the saving the first system resource root as the current best estimate system resource root, retrieving the current best estimate system resource root;

selecting the highest priority assignment;

selecting a task root associated with the selected assignment having a higher task score than the task root associated with the highest priority assignment in the current best estimate system resource;

defining a second system resource root that includes the selected task root and roots associated with unselected assignments of the current best estimate system resource root;

calculating a second system resource root score as a function of the task scores of the second system resource root;

determining whether the first system resource root score is greater than the second system resource root score; and

outputting data associated with the current best estimate system resource root to a user on a display responsive to determining that the first system resource root score is greater than the second system resource root score.

3. The method of claim 2, further comprising:

responsive to determining that the first system resource root score is not greater than the second system resource root score, discarding the current best estimate system resource root; and

saving the second system resource root as the current best estimate system resource root.

4. The method of claim 2, further comprising responsive to determining that the first system resource root score is greater than the second system resource root score, saving an indication of which assignment was the selected assignment.

5. The method of claim 4, further comprising:

determining whether the saved indication indicates a lowest priority assignment in the decision tree; and

outputting the data associated with the current best estimate system resource root to a user on a display responsive to determining that the first system resource root score is greater than the second system resource root score responsive to determining that the saved indication indicates the lowest priority assignment in the decision tree.

6. The method of claim 5, further comprising:

retrieving the current best estimate system resource root;

selecting the assignment having a next lowest priority than the indicated assignment;

select a task root associated with the selected assignment having a higher task score than the task root associated with the highest priority assignment in the current best estimate system resource;

defining a third system resource root that includes the selected task root and roots associated with unselected assignments of the current best estimate system resource root;

calculating a third system resource root score as a function of the task scores of the second system resource root;

determining whether a system resource root score associated with the current best estimate system root is greater than the third system resource root score; and
