Description
Compare a recorded workstation cycle with a supplied allowance.
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.
Compare a recorded workstation cycle with a supplied allowance.
When to use this tool
Use Work Station Cycle Margin when you already have allowedCycleSeconds, observedCycleSeconds and need to compare a recorded workstation cycle with a supplied allowance.
How to use the tool and how it works
- Enter allowedCycleSeconds, observedCycleSeconds. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read marginSeconds, exceedsAllowance. Inspect exceedsAllowance before interpreting the associated values.
Require nonnegative allowed/observed seconds; margin=allowed-observed and exceedsAllowance means observed>allowed.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| allowedCycleSeconds | Allowed Cycle Seconds | Required. Finite number; minimum 0. |
| observedCycleSeconds | Observed Cycle Seconds | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| marginSeconds | Margin Seconds | Required. Finite number. |
| exceedsAllowance | Exceeds Allowance | Required. Boolean. |

}Limitations and assumptions
- Equality is allowed; no appropriate production pace, ergonomics, actual capacity or safe cycle is determined.
- 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.
