01 Answer first
How do you convert bottled-water demand into a line production requirement?
Divide the saleable bottle target by productive planning hours, not by calendar hours. Productive planning hours equal operating days multiplied by shifts, hours per shift, and the buyer’s documented planning-availability assumption. Also convert the same result into liters and finished packs per hour so treatment and packing boundaries use one basis.
02 Where it fits
Position in the project journey
Capacity definition - before line rating, utility sizing, layout, quotation, or performance protocol development.
03 Buyer inputs
What the buyer should prepare
- Saleable bottle demand for one defined period and source date
- Operating days, shifts, hours, and planned downtime or availability basis
- Reference bottle volume and bottles per finished pack
- SKU mix, seasonality, changeover, storage, distribution, and future-capacity cases
04 Allot Tech and manufacturing-resource inputs
What should be clarified or provided
- Proposed full-line rating for the same reference package
- Declared conditions for bottle, cap, label, pack material, utilities, and staffing
- Upstream, downstream, buffer, changeover, reject, and inspection limitations
- Project-specific performance-test boundary, duration, data, and saleable-output rule
Allot Tech coordinates requirement, quotation and project communication. Detailed engineering, manufacture, testing, documentation and confirmed service are performed by selected manufacturing resources according to the signed scope.
05 Technical scope
Questions and work to control
Start With Saleable Demand and a Defined Period
Use a demand case that identifies market, customer, SKU, season, period, source, revision, and confidence. Do not mix a monthly sales target with annual peak growth or warehouse inventory without showing the relationship.
- Build base, peak, and growth cases separately
- Record whether the demand is bottles, packs, pallets, or liters
- Keep stock-building and launch inventory visible
Calculate Productive Planning Time Transparently
Scheduled hours are not all available for saleable production. The planning assumption may represent sanitation, changeovers, maintenance, material replenishment, start-up, quality holds, and expected stops, but it must be owned and reviewed rather than copied as a universal percentage.
- Use a documented assumption for each scenario
- Never label a planning allowance as guaranteed OEE
- Check labor and utility availability across every planned shift
Translate the Same Requirement Across the Complete Line
Bottles per hour helps compare container equipment, liters per hour helps treatment and product-transfer review, and packs per hour connects secondary packaging. Each supplier must still state equipment-specific rating conditions and limiting formats.
- Use the same reference bottle across the response
- Check treatment, blowing, filling, labeling, coding, packing, and conveyors
- Define saleable output and rejected-product treatment
Turn the Result Into an RFQ Input
Copy the result with all inputs and limitations. Ask the supplier to identify the proposed full-line rating, rated format, restrictions, utilities, operating conditions, buffer assumptions, and performance acceptance method.
- Issue inputs and results under revision control
- Require deviations and assumptions in writing
- Recalculate whenever demand or operating conditions change

Buyer questions answered
Practical answers before you request a quotation
Is required BPH the same as the filler nameplate speed?
No. The result is a saleable production requirement based on buyer assumptions. A supplier must propose and support an equipment and full-line rating for the confirmed package and conditions.
What availability percentage should be entered?
There is no universal value. Use a documented planning case based on the actual sanitation, changeover, maintenance, materials, staffing, quality, and operating strategy; run sensitivity cases when uncertain.
Should every bottle size use the same calculation?
No. Bottle geometry, volume, label, pack, blowing, conveying, and machine limits can differ. Run separate cases and ask the supplier to declare each format rating.
06 Responsibility
Assign the owner before the work is due
Land, building and civil work, permits, import and customs, local taxes, site utilities, unloading, lifting, local labor, travel support and commissioning materials are not automatically included. Confirm every responsibility before order.
07 Common risks
What commonly creates avoidable uncertainty
- Monthly demand is divided by all calendar hours
- A filler nameplate is used as saleable full-line output
- Different bottle sizes are treated as equal machine conditions
- A planning allowance is copied into a contractual efficiency guarantee
08 Acceptance or completion
How to know the stage is complete
The calculation records the demand source, date, period, package, operating calendar, planning assumption, scenario result, selected basis, and open constraints.
09 Required documents
Records that support the decision
- Demand and SKU basis
- Capacity scenario calculation
- Reference package data sheet
- Supplier rating and acceptance response
10 Next project step
Turn this decision into a reviewable project brief
Share the product, container, target output, destination and available site information. Unknown inputs can remain open for the first review.
