Strain Index Total Multiplied Score Rater
Original six-factor StrainIndex product with independently edition-matched factors and explicit risk-screen bands, not medical risk estimate. Caller independently establishes matching units, evidence, method edition and applicability; output is not compliance, diagnosis, work-safety approval, geological identity or validated hazard prediction.
Description
A strain index combines separately established multipliers into a product.
A strain index combines separately established multipliers into a product.1
The factor definitions and review bands must be justified before that product is interpreted as a task screen. Use this tool to calculate strain Index Total Multiplied Score Rater from the supplied measurements and assumptions.
When to use Strain Index Total Multiplied Score Rater
Use this tool to calculate strain Index Total Multiplied Score Rater from the supplied measurements and assumptions. Establish the observation protocol, units, task and reference population or review criterion before entering measurements.
How to use Strain Index Total Multiplied Score Rater and understand its results
- Establish the observation protocol, units, task and reference population or review criterion before entering measurements.
- Enter sixIndependentStrainMultipliers, callerLowBoundary, callerHighBoundary, using the field meanings and rules below, then run the tool.
- Read strainIndex, callerBand. Interpret the fields using their units, signs and evidence conventions below.
- If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| sixIndependentStrainMultipliers | Six independent strain multipliers | list of number | Required |
| callerLowBoundary | Caller low boundary | number | Required |
| callerHighBoundary | Caller high boundary | number | Required |
Enter exactly six positive independently scored factors in the order intensity, effort duration, frequency, posture, work speed and daily duration, and nonnegative ordered low/high review bounds. Multiply the factors. A product≤low is low, a product>high is high, and other values are intermediate. The tool does not derive factor grades from raw work observations.
index=ΠsixFactors; band=low if index≤lowBound, high if index>highBound, otherwise intermediate Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| strainIndex | Strain Index; follow the units, sign, ordering and evidence convention stated above | number |
| callerBand | Caller Band; follow the units, sign, ordering and evidence convention stated above | string |

}Limitations and assumptions
The factor definitions and review bands must be justified before that product is interpreted as a task screen. Interpretation depends on the units, sampling scope and exact model described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
