Requirement definition / demand-to-BPH calculation
Water Filling Machine Capacity Calculation
Calculate required filling-machine BPH from daily good-bottle demand and available hours, with explicit efficiency and growth assumptions.
Answer first
Divide daily saleable bottles by net scheduled production hours and the remaining planning-efficiency factor. Apply growth reserve separately. Deduct planned non-running time when defining the hours; the efficiency factor must cover only losses not already deducted.
Calculation worksheet / visible assumptions
Turn daily demand into a reviewable BPH requirement
Use one equation and keep every input visible: required BPH = saleable bottles ÷ net production hours ÷ planning efficiency. Apply growth reserve as a separate final step.
| Worksheet line | Illustrative value | How to use it |
|---|---|---|
| Saleable daily demand | 80,000 bottles | Use good bottles required, not total attempted production. |
| Net production time | 16 hours | Exclude planned non-running time before the calculation. |
| Planning efficiency | 80% buyer assumption | Use a documented planning input; it is not a machine promise. |
| Preliminary requirement | 80,000 ÷ 16 ÷ 0.80 = 6,250 BPH | Carry the exact bottle basis with the result. |
| Growth reserve | 15% buyer scenario | 6,250 × 1.15 = 7,188 BPH; compare the next documented reference band. |
Reference values require project-specific confirmation. The example demonstrates the method only. Buyer demand, efficiency and reserve must be replaced with project inputs.
Capacity planning
Water filling machine capacity calculator
Required BPH = daily saleable bottles ÷ (net hours × remaining efficiency) × growth factor.
Subtract planned breaks and changeovers from hours first. Efficiency covers only losses not already deducted. Count each loss once; 500 ml catalog ratings do not establish the speed of another bottle format.
Not suitable for
Boundaries that need a different platform or review
- Using calendar hours without planned stops or changeovers
- Applying one 500 ml output to every bottle format
- Replacing a supplier performance test with a planning calculation
Inputs required
Evidence to provide before confirmation
- Saleable bottles required per day or shift
- Net production hours available after planned non-running time
- Buyer-defined planning-efficiency factor and growth reserve
- Main bottle plus every SKU that must share the machine
Machine function
What happens at this machine or decision boundary
- Convert demand into a transparent preliminary BPH requirement.
- Run a sensitivity check when hours or planning efficiency change.
- Pass the result, bottle basis and assumptions to the model-selection page.
Configuration decisions
Options that must appear in the proposal
- Whether demand is average, peak or contractual
- Which bottle defines the reference calculation
- How much reserve is justified without oversizing the machine
Interface requirements
Upstream, downstream and utility handovers
- The calculation covers the filling machine, not whole-line OEE.
- Downstream limitations must be reviewed separately at the interface boundary.
- Larger or unstable bottles require a project-specific output confirmation.
Buyer risks
Questions to close before order
- Hiding the efficiency assumption inside a single BPH number
- Adding reserve twice in both demand and model selection
- Choosing a catalog band before freezing the bottle and cap basis
FAT checks
How to verify the agreed basis
- Carry the approved bottle and target good-output basis into the FAT method.
- Record sustained output, stops and rejected bottles separately.
- Compare the observed result with the written order basis, not the calculator alone.
Quotation scope
What the commercial offer should state
- Required saleable BPH and calculation assumptions
- Reference bottle, additional formats and expected changeovers
- Proposed model band and project-specific output confirmation
- FAT run method, measurement boundary and exclusions
Questions to settle before requesting a quote
How do I calculate the required bottles per hour?
Divide daily saleable bottles by net scheduled production hours and the remaining planning-efficiency factor. Apply growth reserve separately. Deduct planned non-running time when defining the hours; the efficiency factor must cover only losses not already deducted.
What capacity is needed for 48,000 bottles per day?
Illustrative assumptions: 8 net hours, 80% remaining planning efficiency and 10% growth reserve. The requirement is 48,000 ÷ (8 × 0.80) × 1.10 = 8,250 BPH. These are buyer planning assumptions, not a tested machine performance claim.
Can I use a 500 ml rating for 1.5 L bottles?
No automatic conversion is reliable. Larger fill volume, bottle geometry and transfer behavior can change output. Ask for a separate sustained good-bottle rate for every required format, measured with the approved cap and agreed FAT conditions.
