SHAR Production Capacity Planners

This dataset by SHAR Production contains 100 deterministic synthetic workload scenarios for 25 bilingual production capacity planners. Each planner calculates adjusted workload, daily capacity, estimated days and a transparent planning band from explicit inputs.

scenarios.jsonl contains inputs, expected outputs and reproduced results. catalog.json contains bilingual planner definitions and units.

Synthetic scenarios and results use CC-BY-4.0. The source implementation and documentation use MIT. Outputs are planning estimates, not delivery guarantees. No client data, credentials, analytics or performance claims are included. AI assistance was used under SHAR Production's publishing responsibility.
