SAP OEE (Overall Equipment Effectiveness) optimises production services

OEE (Overall Equipment Effectiveness) is a familiar indicator within the TPM concept (Total Productive Maintenance). As a key performance indicator it serves to determine, supervise and optimise availability, performance level and quality in relation to the production process.

With the help of measurable KPIs, the SAP ME- / MII-based OEE also serves to keep production services within view at all times as well as to recognise where and why losses in performance occur. An order-related profitability calculation can be carried out and goal-oriented counter-measures can be implemented quickly and effectively.


OEE 4.0 in overview

The term Overall Equipment Effectiveness (OEE) describes a key performance indicator created by the Japan Institute of Plant Maintenance. It is one of the results which arose from the decades-long development of the TPM concept (TPM: Total Productive Maintenance).

Overall Equipment Effectiveness (OEE) measures the actual effectiveness of a plant in which it sets the output quantity free from defects in relation to the maximum possible quantity. The OEE KPI is comprised of the plant, the performance level as well as the quality level. OEE is a measurement for the added value of a plant and allows the operator a further economic view of the technical plants.

Key performance indicators, like the OEE, process throughput, set up level or level of document use (capacity) are always available in their latest form thanks to automated recording. Goal-oriented opportunities for optimisation follow from the analysis of production units, individual products, time periods, defect times and sources. Losses in time, performance and quality reduce effectiveness. Because these sources of loss affect both sides, an integral form of optimisation is required. In summary, the record of the OEE offers an integral instrument which monitors the effectiveness of the plants and thereby facilitates a rapid, goal-oriented reaction to losses.

Here, integral means that all areas of the company are included. So, for example, logistics is decisive for the preparation and supply of raw materials, maintenance is responsible for running the plants free from disruptions and quality management is responsible for products free from defects.
