As scheduling parameter setting is new parameter functionality in AX
2012 under setup of organization administration.
Here is a brief description of these settings which could be used to get
the optimum results:
Scheduling timeout enabled:
- If checked, the scheduling engine will
limit itself to X seconds (X being the “maximum scheduling time per sequence”)
in order to find a schedule. If one cannot be found in this time, scheduling
fails; - If unchecked, scheduling can potentially
run forever if there is some problem with the route that could not be detected
either during setup time or run time; - Recommendation: checked;
- Time recommendation: the time depends on
how complex are the routes that the customers want to schedule – here
it’s true that trial and error is the way to go, since it depends
on your data composition, how powerful is the server where scheduling is
running, etc.
Schedule optimization timeout enabled:
- If unchecked, the scheduling engine will
run potentially forever, in order to try all job-resource assignment
combinations and find the best possible schedule; - If checked, the scheduling engine will
only try for Y seconds (Y being the “optimization attempts timeout”) to find
more optimal solutions that the one found initially; if the timeout value is
zero, it’s effectively the same thing as saying “don’t try to optimize beyond
the first solution”. - Recommendation: checked;
- Time recommendation: give it a try with
0 and with at least as much time as it usually takes to find the initial
solution – if the solutions are not significantly better based on what the
customer expects, don’t use it / use 0 (the scheduling engine already employs
many heuristics in the initial solution search that lead to a good quality
schedule).
