Many cycle calculations in whiteboard will show the actual, expected and variance between these two calculations.

Before listing the calculations, here is a description of a few of the variables used for the calculations:

• Uptime - the amount of time the machine actually was up. ¹

• Scheduled - the amount of time the machine was expected to be up

• Total - the amount of parts that were actually made

• Expected - the amount of parts that were expected to be made

• Cycles - the amount of cycles that actually occurred (does NOT include unscheduled).

• Expected Cycles - the amount of cycles that were expected (includes unscheduled!) ²

Cycle Time [seconds per cycle]

1. Actual Cycle Time = Uptime [seconds] / Cycles *

2. Expected Cycle Time = Scheduled [seconds] / Expected Cycles * ²

3. Cycle Time Gauge = Actual Cycle Time - Expected Cycle Time

...

1. Actual SPH = Cycles / Uptime [hours]

2. Expected SPH = Expected Cycles * / Scheduled [hours]

3. SPH Gauge = Actual SPH - Expected SPH

...

1. Actual SPM = Cycles / Uptime [minutes]

2. Expected SPM = Expected Cycles ²/ Scheduled [minutes]

3. SPM Gauge = Actual SPM - Expected SPM

...

...

¹ Note: Uptime technical definition:

1. Scheduled Time; AND

2. (Classification = Uptime OR Classification = Slow Running)

Classification comes from the ReasonState.

² Note: use a measure filter to remove unscheduled time from Expected and Actual Cycle fieldsfield:

• Unscheduled Time - Understanding your Unscheduled Production metrics

• Use “Measured Value” filters to remove Unscheduled time from [Expected Cycles] and [ Cycles] and [uptime] . "Measured Filters" - Creating Formulas Based on Criteria and Conditions
