TWS has an option to prioritize jobs based on ERT and MaxRT. It works like this: in situations where two or more jobs are in contention to start first (due to a limit on the maximum number of simultaneous runs, or dependency on a limited resource), the engine performs an on-the-fly forecast to see which job should start first. It does this with the aim of ensuring that MaxRT conditions are met — not just for these jobs, but for all successors.
Is such a capability envisioned? Does it fall within the scope of your survey regarding ERT?
