Overall Equipment Effectiveness (OEE) is a single-number measure of performance, availability and quality.<\/p>
Indeed, by using this indicator, operators and managers can quickly see how a machine is performing. Many people believe that SRT is a magic number and, once implemented correctly, your operations will magically improve. In this article, we discuss how SRT can help and what to look out for. I'll leave it to you to decide if it's magic.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
As I mentioned above, TRS has three components: availability, performance and quality. Below is a definition of each and how they create critical visibility on a machine or cell.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
Availability is a single number representing the runtime of a machine. This indicator takes into account planned and unplanned maintenance, waits, changes and lack of supply.\u00a0<\/p>
Using anomaly codes to track company downtime can determine root causes and develop corrective actions to prevent these problems from occurring in the future.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
The performance part of the OEE calculation is a measure of the parts actually produced in relation to the standard. The standard is the ideal number of parts a machine can produce in a given time. As most machines are programmed according to the standard, this is an important measure.\u00a0<\/p>
If the machine produces too much below the norm, the schedule won't be met. If it produces above the norm, you may have excess capacity.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
Quality measurement is the simplest of the three: the ratio of good parts to bad parts.\u00a0<\/span><\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t Using the three measures above, companies can use the synthetic rate of return to help uncover the 6 big losses. These losses are the most common reasons for reduced efficiency and capacity in a plant.\u00a0<\/p> Downtime: unplanned maintenance, breakdowns, ....<\/p><\/li> Settings: Change of series, settings, minor adjustments<\/p><\/li> Start-up: Quality of first product, rejects, ...<\/p><\/li> Micro-arrests: Obstructions, adjustments, ...<\/p><\/li> Decrease in speed: Operator efficiency, ageing equipment, ...<\/p><\/li> Manufacturing defects: Scrap, Returned material, ....<\/p><\/li><\/ul><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t The OEE is calculated using the formula Availability x Quality x Performance. Any one of these factors can vary and produce the same OEE rate. For example, one of these factors may vary and produce the same OEE rate:<\/p>6 major losses<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
Could the TRS be misleading?<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
