Overall equipment effectiveness report

The report properties and the KPI calculation rules

Edit KPI

The report displays the following KPIs:

  • «Overall equipment effectiveness index» («ОЕЕ- index»)

  • «Availability»

  •  «Performance».

ОЕЕ-index calculation formula is as follows:

ОЕЕ= А * Р * Q= А * Р, where

А – Availability, Р – Performance, Q – quality indicator which is assumed equal 1 (100%).

KPI «Performance» for the basic module of the MDCplus is calculated as follows:

Р = (APT - MST) * “Avg. F%” / APT, where:

APT - Actual production time

MST - Minor stop and waiting time

“Avg. F%” – average corrector feed value during the NC program execution.

Monitored states

The measured parameter that controls the feed corrector position must have been specified in the “States, downtime reasons, parameters” directory of the MDCplus Server and selected in the “Avg. F%” fields in the “Settings” – “Production monitoring settings” section for the corresponding machine tools. For example, «Feed corrector F%» measured parameter.
