Evidence stage
CapabilityA demo, benchmark or paper shows the task can be done. Updates what the technology can do — not what employers will do.
Tasks this bears on
Scheduling and line balancing
Balancing work across stations and scheduling production to meet due dates with the capacity available.

Where this applies
A study of reinforcement-learning dispatching in semiconductor front-end fabs, tested on open-source fab models and on a real industry dataset. The paper reports improvements of up to 4% in tardiness and up to 1% in throughput on the real dataset, against double-digit percentage improvements in tardiness on the less complex open-source models, and says the real dataset is not available for commercial reasons. Co-authors include a simulation software company.
What this means
AI scheduling works, but on a real factory the gain is a few percent, not the large improvements seen on textbook models. The engineer who knows the real constraints is still where most of the value is.
What it does not yet show
A research study with non-public industry data; not a deployment.
What you can check
Open arXiv 2505.11135 and find "up to 4 % regarding tardiness" in the paper.
Does it change the assessment?
No — and this stage does not move it either. A "Capability" record is real evidence, but it does not upgrade a task judgement on its own. The 1 linked judgement above stand where they were.
