Production Monitoring - OEE

Live Production Tracking is positioned to make visible how production progresses from planned work to actual results and where production time is lost. The production manager, shift supervisor, engineer and operator follow quantity, time and downtime information of the same job according to their tasks.

In the first step, the plant's machines, lines or stations are defined. It is determined which job will be done at which station. States such as running, waiting, setup, breakdown, material shortage and quality hold are arranged according to the business's real processes. Data can be taken from a suitable machine connection, from operator entries, from an existing system or from a file import. If there is no connection, work can start with user records; how current the screen is depends on the data collection frequency.

The target scope covers work order progress, planned and actual quantity, good production, scrap, rework, cycle time, setup time and downtime reasons. Working conditions are taken into account when comparing shifts, products or similar machines. A machine producing less is not, on its own, turned into a conclusion that the operator performed worse.

In OEE evaluation, availability, performance and quality are handled together. For this, planned production time, a suitable ideal cycle time, total quantity and the quantity produced right the first time must be defined correctly. The time a machine is merely switched on is not OEE. If data is missing, a running and downtime report can be offered; an incomplete calculation is not shown as if it were a finished OEE.

In processes such as sandblasting and painting, the tracking unit is not always the piece; a batch, a surface area or another defined production unit may be needed. If parts have different characteristics and processing times, efficiency is not compared between lines without taking these into account.
