Re: [Planner] Opensched and resource scheduling

["lincoln phipps openmutual net" <lincoln phipps openmutual net>]

I've just raised a Bugzilla,
http://bugzilla.gnome.org/show_bug.cgi?id=139443
which I feel offers a suggestion on how to resolve the
issue of working out how to resolve some of the
overallocations.

The priority field is now effective in CVS. Planner doesn't
yet use this field but planner could use this field as follows;

An example: if you have TASK 1,2,3 and TASK2 and 3 are both
linked to TASK 1 as FS and both use the same/similar set of
resources of 100% each and so are now at MAX (100%) then the
"higher" priority task out of 2 or 3 should take precedence
over the "lower" priority task for the actual start.

Thus the start of e.g. TASK 3 is the,
max(f(relations(predecessor))->end, f(priority(siblings))->end)

and not just max(f(relations(predecessor))->end)

As mentioned if priority is 0 then its never checked.

Other things...

-we would have to have flags to turn on/off this behaviour
across a project and also a task (A "UsePriority" flag)

-we would have to have a project-wide definition as
define if 1 is the "higher" or "lower" priority

-if priority is used then we would have to have a project-wide
check to make it take into account resources
(range of no resources, any resource or all resources).
If no-resources then this means that a higher priority
task would always be completed before a lower priority task
within its siblings.

Other note: priority would only ever be compared within
the siblings but ...there is no reason why you couldn't
also set a priority to a summary tasks to resolve contention
within its siblings and so on to the top level tasks,
thus effectively allowing levelling of the whole project.

Thoughs on this ?.
