ERP & MRP Planning calculator
Production Schedule Capacity Calculator
Production Schedule Capacity checks whether the planned schedule can produce enough good units in the selected shift, day, or week. It includes downtime and yield so planners do not treat theoretical output as shippable output.
What this calculator does
- Estimate good production output from scheduled cycles, units per cycle, uptime, and first-pass yield.
- a production scheduler needs to confirm whether scheduled capacity covers the build plan
- It estimates how many good units a production schedule can realistically deliver.
Formula used
- Gross scheduled capacity = good units per cycle × scheduled production cycles
- Good scheduled capacity = gross capacity × expected uptime × expected first-pass yield
Inputs explained
- Good units per production cycle: Use parts per cycle, cavities, assemblies per batch, or units per takt interval for the scheduled routing.
- Scheduled production cycles: Count cycles available in the shift, day, or week after planned breaks and changeovers.
- Expected work-center uptime: Use recent availability or planned uptime after maintenance, staffing, and material constraints.
- Expected first-pass yield: Use accepted output percentage for the same part family, route, and quality standard.
How to use the result
- Use it during ERP cleanup, MRP review, production scheduling, S&OP prep, purchasing decisions, shortage meetings, capacity planning, or daily shop-floor execution reviews.
- This is a planning estimate. Confirm final commitments against current ERP/MRP records, released BOMs and routings, inventory accuracy, supplier commitments, open work orders, quality holds, and shop-floor constraints.
Common questions
- What is the Production Schedule Capacity calculator for? It estimates how many good units a production schedule can realistically deliver.
- What information do I need before using it? You need units per cycle, scheduled cycles, expected uptime, and expected first-pass yield.
- How should I use the result? Use it to accept or reject a schedule, add overtime, split work centers, or move demand to another period.
- When is the result only an estimate? It is only an estimate when demand, inventory, lead time, routing hours, setup time, yield, supplier dates, or work-center capacity comes from forecast assumptions or stale ERP data instead of current orders and recent execution history.
