Description
Calculate an operator's supplied busy fraction within an assembly cycle.
Production quantities distinguish planned time, operating time, setup, cycle time, demand, first-pass good units and accepted rework. A local availability term is not complete OEE, and equal time-per-unit arithmetic is not measured capacity. Counts and durations must share one nonoverlapping accounting scope.
Calculate an operator's supplied busy fraction within an assembly cycle.
When to use this tool
Use Assembly Operator Cycle Share when you already have operatorBusySeconds, cycleSeconds and need to calculate an operator's supplied busy fraction within an assembly cycle.
How to use the tool and how it works
- Enter operatorBusySeconds, cycleSeconds. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read busyFraction, idleSeconds. Use the output convention below.
Require cycleSeconds>0 and busy seconds within cycle; return busy/cycle and cycle-busy as idleSeconds.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| operatorBusySeconds | Operator Busy Seconds | Required. Finite number; minimum 0. |
| cycleSeconds | Cycle Seconds | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| busyFraction | Busy Fraction | Required. Finite number. |
| idleSeconds | Idle Seconds | Required. Finite number. |

}Limitations and assumptions
- Remaining time is an arithmetic remainder, not verified idle capacity, labor effectiveness or an appropriate workload.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review the full time study, production ledger and process definition before interpreting performance. Use a complete capacity, OEE or workflow analysis when bottlenecks, quality, concurrency and operating constraints matter beyond one local term.
