How to calculate OEE. Formula of Overall Equipment Effectiveness. Throughout this post I will be using examples. Do the same as above to calculate the three parameters and then last calculate the total OEE number. Components of OEE Three main factors make up the OEE calculation: They are • Availability (A) C. Quality • Performance (P) The final factor on the overall OEE calculation is quality. The second is the current position. Using erroneous values or omitting one of these metrics can significantly alter the results in unpredictable ways. OEE Calculation Example OEE = Availability x Performance x Quality = 88 x 85 x 97 = 72.5% How to improve OEE Using IoT, mobile app, predictive maintenance OEE Automation Software. Batch sizes and process inherent particularities can hugely affect OEE. OEE = 64.8% Although this is an acceptable calculation of OEE, it doesn’t give us enough insight to know what we need to change if we want to improve it. Some exclude preventive maintenance from the availability calculations, others exclude holidays others don’t. Obviously this was a very simplistic example but even in such a simple example it becomes clear that the OEE Formula can be used to tell a story. Basically OEE is about (as the name says) effectiveness: it is the rate between what a machine theoretically could produce and what it actually did. To calculate an OEE, we need a few data points. The most widely used way to calculate OEE is calculated by multiplying three individual metrics : … To make this example more simple, let suppose you have to make 10 cups of tea and having 10 tea bags and 10 milk bags than your effectiveness is 100%. Example Data. The shift has two 10 minute breaks and a 5 minute clean up period. The first point is the point on the horizon. To understand the OEE it is crucial to introduce the 6 big losses. Continuous plants tend to be relatively straightforward for setting up an uptime measurement. An 8 hour shift is scheduled to produce three parts as shown in the schedule below. From manual, semi-automatic, to fully automatic operations or processes, implementing OEE tools as. The tables to the left contains an example with some data from a shift that have been used to calculate an OEE value. OEE = Availability x Performance x Quality *Calculation formula taken from www.oee.com. Calculation of OEE. So the fastest way to calculate it is simple: If you take the theoretical maximum speed (for example 60 products per minute) you know that at the end of a 480 minutes shift there should be 28,800 units. Availability is the percentage of time that a machine is available to produce during the measured period. Over 5 days, the capacity is 800 units. Imagine a normal workday from 9 to 6 with a 1-hour lunch break. Steps . Example of OEE Calculations Many manufacturers are already using OEE, both as a KPI and as a catalyst for change. Calculation: TEEP = Loading x OEE Example: A given Work Center experiences OEE of 76.67%. These are only some examples of bad practices in OEE calculation. We’ll look at an OEE calculation example to explain how to calculate availability, performance and quality. It's best used to identify problem areas that will take further analysis for key performance improvement.

This OEE Report Template is used by machine operators and quality managers to identify any of the Six Big Losses in daily manufacturing operations. 1. OEE calculation Example. 6 Big Losses. OEE Quality is similar to First Pass Yield, ... Not part of the OEE calculation (it is part of the TEEP calculation). Operations pros identify the core factors of the OEE measurement as Availability, Performance and Quality. OEE is the result of: Availability % x Performance % x Quality % Availability . 2. It should be able to deliver specific number of units in a given time. Now let’s walk through a complete example using the method 2 of OEE calculation. Theoretically, the machine should produce 48 parts over the course of an eight hour shift. The six big losses are: 1) Breakdown 2) Changeover 3) … After you calculate each of these metrics, OEE calculation is pretty straightforward: multiply availability, performance and quality. This factor is then: III. Using OEE is not an absolute measure; it can break down in various areas. With some minor modification to the model of Figure 1-5, losses can generally be routinely accounted. Instead, use it as a measure of productivity that needs to be improved. Set a target for periodic improvement, not an absolute value. Of course, the OEE calculation is closely linked with … Figure out the Availability component of OEE. How is OEE calculated? Work Center Loading is 71.4% TEEP = 71.4% Loading x 76.7% OEE = 54.8% Stated another way, TEEP adds a fourth metric 'Loading'. The OEE calculation provides focus and simplicity to aid in decision making. OEE calculation example. For this reason, insufficient data collection is among the top OEE calculation mistakes that we see. As an example, say a machine produces 1 part per cycle and a cycle takes 10 minutes to complete including setup. OEE FAQ presents commonly asked questions about OEE, with practical, real world answers and advice. Sample Calculation of Batch Plant OEE. In 8-hour day, it should have the ability to produce 160 units. The basis is as simple as it is brilliant; it assumes a theoretical maximum capacity on the one hand and the actual output on the other. A real-world example is given to demonstrate the mechanics of a typical OEE calculation. OEE [ OVERALL EQUIPMNT EFECTIVENESS ] #OEE | How to Calculate OEE ? In the above example, it looks like operators tried to make up for lost down time by pushing WC1 to the brink of capacity and ended up taking a quality hit. To calculate OEE correctly, it is essential to have enough data for availability, performance, and quality scores. This is • Quality(Q) simply a measure of good product divided by the total product (for the job, shift, day, week etc). If it can produces 20 units in an hour. The preferred way to calculate OEE is mathematically equivalent to the simple formula described above, but provides a much richer understanding of waste in the manufacturing process by breaking it down into three loss factors: Availability Loss; Performance Loss; Quality Loss; OEE is the ratio of Fully Productive Time to Planned Production Time. Calculating OEE illustrates how the three OEE Factors are calculated and breaks them into the specific elements that are required to develop the OEE percentage. Master class OEE.
