Production Event Capture Rate at 99% system reliability factor: a worked example

This scenario runs the production event capture rate calculation on the strong side: 99% system reliability factor, with every other input held at its documented default. Use to assess MES data capture density. A low event rate per production hour may indicate missed events, disconnected stations, or overly coarse data granularity that limits analytics value.

The inputs for this scenario

  • Production events logged in period: 8,400 events (unchanged)
  • Production hours in period: 160 hr (unchanged)
  • System reliability factor: 99 % (raised for this scenario; the documented default is 96)

Working through the calculation

  • Applying the documented formula (Raw capture rate = production events logged / production hours) to the inputs above produces each figure below.
  • At this operating point the engine returns 51.98 units/hr for effective event capture rate, the number this scenario is built around.
  • At this operating point the engine returns 52.5 units/hr for raw throughput.
  • At this operating point the engine returns 99 % for system reliability factor.
  • At this operating point the engine returns 160 hr for production hours.

How this compares with the baseline

  • Against the tool's baseline example, where system reliability factor sits at 96% and the headline result is 50.4 units/hr, this scenario comes in 3.13% above the baseline at 51.98 units/hr.
  • Use it when sizing MES data ingestion, validating event-stream completeness, or diagnosing gaps between expected and recorded production events. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Effective event capture rate: 51.98 units/hr (headline result)
  • Raw throughput: 52.5 units/hr
  • System reliability factor: 99 %
  • Production hours: 160 hr
