Repeat Task constraints
Repeat tasks may have constraints or advantages due to overlapping schedule allowances or batch run efficiencies etc.
PRETTI chart has these constraints:
|duration||max_concurrent||Maximum Concurrent Tasks||The maximum number of a specific activity that can operate at the same time and indefinitely.|
|duration||max_run_time||Max Run Time||A constraint of a maximum time a batch can run before a break.|
|duration||max_tasks_per_run||Max Tasks per Run||A constraint of a maximum number of times a task can be repeated without a break.|
|duration||max_overlap_pct||Percent Maximum Overlap||A decimal percentage (0 to 1) of maximum amount of overlap between concurrent operations of same activity.|
Empty values get defaults:
- Unlimited concurrent tasks.
- No forced breaks.
- Unlimited tasks per run.
- No overlap. Overlapping doesn't happen when there are unlimited concurrent tasks.
cost and eco2 constraints
Sometimes there are cost or other efficiencies when tasks are batched.
|cost||max_discount_pct||Max Discount Pct||Maximum Discount for batch (contiguous) runs. Expressed as a percentage of a run without discounts equals 0 (0%).|
|eco2||max_reduction_pct||Max Reduction Pct||Maximum Reduction for batch (contiguous) runs. Expressed as a percentage of a run without reductions equals 0 (0%).|
