Conservation Lab Annual Throughput Objects Estimate Calculator
Budget expected complete lab objects using caller productive hours and explicit complexity mix, not universal conservator-hour multipliers or a guaranteed integer mix allocation.
Description
Laboratory throughput depends on productive hours and object complexity mix.
Laboratory throughput depends on productive hours and object complexity mix. A fractional expected mix differs from an exact integer allocation.
Budget expected complete lab objects using caller productive hours and explicit complexity mix, not universal conservator-hour multipliers or a guaranteed integer mix allocation.
When to use Conservation Lab Annual Throughput Objects Estimate Calculator
Use this tool to budget expected complete lab objects using caller productive hours and explicit complexity mix, not universal conservator-hour multipliers or a guaranteed integer mix allocation.
Prepare the collection, exposure, scheduling or financial records required for this calculation. Keep row order and the declared units consistent.
How to use Conservation Lab Annual Throughput Objects Estimate Calculator and understand its results
- Prepare the collection, exposure, scheduling or financial records required for this calculation. Keep row order and the declared units consistent.
- Enter availableAnnualProductiveHours, callerHoursPerObjectByClass, plannedClassMixFractions using the field table and calculation rules, then run the tool.
- Read mixMeanHoursPerObject, modeledCompleteObjectsAnnualThroughput, unusedProductiveHours. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| availableAnnualProductiveHours | Available annual productive hours | number | Required |
| callerHoursPerObjectByClass | Caller hours per object by class | list of number | Required |
| plannedClassMixFractions | Planned class mix fractions | list of number | Required |
Align positive class hours and fractions in [0,1] summing to one within 1e−12, with nonnegative productive hours. Return mean, whole expected throughput and remainder hours.1
Paired lists must be nonempty and have equal lengths.
mean hours = Σ class hours × mix fraction; objects = floor(available hours/mean) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| mixMeanHoursPerObject | Mix mean hours per object | number |
| modeledCompleteObjectsAnnualThroughput | Modeled complete objects annual throughput | number |
| unusedProductiveHours | Unused productive hours | number |

}Limitations and assumptions
Caller estimates are not universal conservator multipliers or a completion guarantee.
Numbers and computed results must be finite; overflow produces an error. Numeric lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Conservation Treatment Backlog Aging Days Calculator: Retain closed service time versus right-censored open backlog age with explicit status, rather than age every completed object to today; zero maximum means no open records. For a complementary task, use Digitisation Batch Throughput Items per Day Calculator: Track QC-accepted digitization throughput separately from capture count across actual productive-day exposure; no implied metadata completion or full preservation workflow completion.
