Capacity planning: the constraint is the forecast
A plant, a ward, a classroom, a network link — capacity is a ceiling. The forecast is whether you will hit it, and when. Over-build is capital. Under-build is a queue, a blackout, or a denied admission.

Forecast the load, know the ceiling
A plant, a ward, a classroom, a network link — capacity is a ceiling. The forecast is whether you will hit it, and when. Over-build is capital. Under-build is a queue, a blackout, or a denied admission. Forecast the work (orders, patients, packets, enrollments). Utilization is a ratio that moves when either side changes. You will not know which.
Two horizons
Adding a line, a wing, or a fiber build has a long lead. Running this week’s shift has a short one. Those are different goals. Stretching the daily production path to 36 months is how you get a confident expansion case on a model that never saw a cycle.
- Short: can we clear this week’s load with the lines we have?
- Long: a wide interval, plus scenarios for demand and for a line down.
- Queues hide the miss. If you only see wait time, you are late.
Queues hide the miss
Hospitals divert. Networks drop. Factories build WIP. The demand still happened. Training on the throttled output teaches the model your constraint, not the load. Flag the throttle, or forecast arrivals / orders, not throughput, when the ceiling binds.
Base path vs promo-on
Load as a goal, capacity as a scenario
Forecast the load in Predict.ai. Then run a scenario with a line down, a classroom closed, or a link degraded. You see whether the path still clears the constraint — before you buy a tool or deny a cohort. Alerts when load leaves the band are how you notice the squeeze without waiting for the queue to become a scandal.
FAQ
- Is utilization a good target to forecast?
- Usually no. Forecast the work (orders, patients, packets). Utilization is a ratio that moves when either the numerator or the denominator changes. You will not know which.
- How do I plan a factory expansion?
- A long-horizon, wide-interval forecast of output or demand, plus a scenario for the new line. Do not use the daily production path stretched to 36 months.

Guide
Choosing a forecast horizon
The horizon is how far ahead the forecast looks; the grain is how finely it ticks. Pick both from the decision they serve — lead time, planning cycle, and how fast the world can change — not from what the model can print.
Guide
Workforce and staffing forecasts
Nurses, agents, cooks, field techs — the cost is people on a clock. A staffing forecast is arrivals or contacts by interval, with a band wide enough for a call-out list, not a single headcount that makes Tuesday look like Saturday.
Guide
Patient flow forecasting
Clinics, EDs, and wards are queues with clinical consequences. Forecast arrivals by hour and service, not a daily average that hides the 11am surge. Staffing and beds are downstream of that path.
