Turn a reference BPH into a transparent shift scenario
The interactive calculator on this page keeps availability, rate performance and quality yield visible so a zero-loss machine rate is not mistaken for expected saleable output.
Direct answer
Enter one format-specific reference line rate in bottles per hour, planned production hours, availability percentage, rate-performance percentage, quality-yield percentage and bottles per finished pack. The calculator multiplies reference rate by planned hours and the three percentage factors to estimate whole good bottles, rounding down to a complete bottle count. It then divides that result by bottles per pack, showing complete packs and any remaining bottles, alongside the zero-loss reference. The tool is an illustrative scenario, not a guaranteed forecast. Use one bottle and pack throughout each calculation and replace assumptions with consistent site records, an agreed count point and comparable time definitions.
System focus 01
The calculator accepts reference line rate, planned production time, availability, rate performance, quality yield and bottles per finished pack. Reference rate is entered in bottles per hour and planned time in hours; the three factors are percentages and pack size is a whole-bottle count. Keep the bottle, cap, label and pack unchanged within a scenario because one reference BPH cannot describe mixed formats. The input fields prevent percentages above 100 and require positive values, but a mathematically valid entry can still be an unrealistic business assumption. Document the source and date of every input outside the calculator.
System focus 02
Use a reference rate for the complete named line boundary and selected package, not the fastest isolated machine. The filler, blower, bottle supply, labeler, packer, utilities and transfer system may have different ratings and conditions. State where bottles are counted: filler discharge, packer infeed or accepted finished packs can produce different results when rejects and work in process exist. A supplier rating may be a starting case, while a validated operating record can support later scenarios. Do not reduce the reference rate secretly for expected losses and then apply loss factors again, because that can double-count the same limitation.
System focus 03
Planned production time should follow one stated rule for shifts, breaks, sanitation, changeover, maintenance and no-demand periods. Availability represents the share of planned time that the line is running under the selected policy. Rate performance represents output pace against the reference rate during run time. Quality yield represents good bottles divided by total counted bottles on the same boundary. These definitions echo OEE logic but are user-entered scenario assumptions, not measured automatically by the page. Use evidence from comparable format and operating windows, and keep exclusions visible so different scenarios are not made attractive by changing definitions.
System focus 04
The implemented formula is reference BPH multiplied by planned hours, availability, rate performance and quality yield. Percentages are converted to decimal factors. The result is rounded down to whole good bottles, then complete packs are calculated by whole-number division; any bottles that do not complete a pack appear as a remainder. The zero-loss reference is simply rate multiplied by planned hours and is also rounded down for display. The result does not calculate pallets, warehouse space, treatment flow, profit, demand or confidence range. It also does not predict which loss will occur, so scenario output should remain a planning comparison.
System focus 05
Create low, base and well-supported improvement cases using the same format, line boundary and time rules. Compare the result with demand, treatment volume, packaging consumption, labor, warehouse throughput and dispatch capacity outside the calculator. For a new project, use the gap between scenarios to identify which evidence belongs in supplier acceptance and ramp-up plans. For an operating plant, reconcile calculated good bottles with shift and finished-goods records before changing assumptions. Never present one scenario as a promised output, and avoid combining independent optimistic percentages without considering whether the underlying improvements can occur together.
Interactive capacity scenario
Keep one bottle and pack format throughout the scenario. Availability, rate performance and quality are explicit planning assumptions, not hidden deductions.
Illustrative planning model only. Replace the assumptions with consistent site evidence and confirm the reference bottle, count point, pack pattern, planned-time rules and acceptance method before making an investment or production commitment.
Calculator input worksheet
The calculator supplies arithmetic; this worksheet supplies the operating meaning needed for a decision.
| Input | Definition to record | Possible evidence | Common error |
|---|---|---|---|
| Reference BPH | Rate for one format and complete boundary | Agreed specification or validated record | Using the fastest standalone machine |
| Planned hours | Time included under one production policy | Shift calendar and time classification | Counting unavailable or no-demand time inconsistently |
| Availability | Run time divided by planned time | State and stop records | Hiding excluded downtime |
| Rate performance | Actual pace against reference during run time | Counters and run-time timestamps | Double-counting a derated reference |
| Quality yield | Good bottles divided by total bottles | Reject and release reconciliation | Ignoring start-up or unfinished output |
| Pack count | Whole bottles in one finished pack | Approved packaging specification | Mixing several pack patterns in one run |
The interactive result is an illustrative scenario. Preserve the selected format, count point, time policy and evidence behind all six inputs.
Buyer questions
Use these answers as a project-planning starting point. Final equipment and performance remain subject to the confirmed brief.
Good bottles equal reference BPH multiplied by planned hours, availability, rate performance and quality yield, with percentages expressed as decimals. The displayed bottle result is rounded down, then divided into complete packs with a remainder.
No. It applies user-entered assumptions and does not observe the actual line, materials, operators or utilities. Treat the result as an illustrative scenario and validate inputs with consistent evidence before commitments.
No. Run a separate scenario for each controlled bottle and pack. Then build an external schedule that includes the planned quantity, time, changeover and losses for each format without averaging incompatible rates.
They represent different loss mechanisms: qualifying stopped time, slower-than-reference running and non-good output. Keeping them separate makes assumptions reviewable and reduces the risk that one unexplained efficiency percentage hides several definitions.
