Re: Resource overutilization

After some thinking I think a more complete solution to over-utilization
would be:

1-Add a property to each task (can be overlapped, cannot be overlapped).
2-If task cannot be overlapped, use the "priority" property to schedule
it with respect to other tasks using the same resource, use any-order
for tasks with same priority.
3-For tasks with SAME PRIORITY that can be overlapped, extend the
duration of the tasks so that the total time spent on the task by
resource adds up to his full time commitment.
example: tasks A and B (each taking one day) should both be done by
resource R, If tasks A and B are overlap-able, then show the duration as
two days for each.
In this context, overlap-able tasks with same priority form a
"super-task" that can be scheduled using its priority with respect to
other non-overlap-able tasks for the same resource.  

Thanks for reading my comments and I look forward to your feedback.
