If you need to calculate OEE for a company or business, or a single department or location, here are the common steps involved in figuring up this benchmark. Note: Use the same time unit in all calculations. With some minor modification to the model of Figure 1-5, losses can generally be routinely accounted. 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. Calculating OEE: A real life example. Let me show you why by comparing the three different ways to calculate an OEE. Sample Calculation of Batch Plant OEE. 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. OEE calculation example. OEE = Availability x Performance x Quality *Calculation formula taken from www.oee.com. First, we must find the maximum rate our machines can produce. Calculation of OEE. For this reason, insufficient data collection is among the top OEE calculation mistakes that we see. Imagine a normal workday from 9 to 6 with a 1-hour lunch break. 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'. 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. 8 hours * 60 minutes per hour = 480 minutes / 10 minutes per cycle = 48 cycles * 1 part per cycle = 48 parts . Using erroneous values or omitting one of these metrics can significantly alter the results in unpredictable ways. Formula of Overall Equipment Effectiveness. Theoretically, the machine should produce 48 parts over the course of an eight hour shift. An industrial IoT application coupled with a strong predictive maintenance system can improve overall equipment effectiveness by at least 10x. Calculation: TEEP = Loading x OEE Example: A given Work Center experiences OEE of 76.67%. This OEE report template empowers you to efficiently perform the following: From manual, semi-automatic, to fully automatic operations or processes, implementing OEE tools as. Availability Loss: Availability is the ratio of Run Time to Planned Production Time. OEE In Action. This comes from an obsession with the absolute value of the OEE. Before moving to the OEE Calculation is important to understand that OEE one of the indicators of the TPM and the TPM is one of the Lean Tools. OEE FAQ presents commonly asked questions about OEE, with practical, real world answers and advice. So your OEE indicator would be 92% * 83% * 80% = 61% . Overall Equipment Effectiveness (OEE) is a manufacturing performance metric that is used to identify lost opportunities and measure improvement efforts. As an example, say a machine produces 1 part per cycle and a cycle takes 10 minutes to complete including setup. To close the valuation for that day and calculate the Overall Equipment Effectiveness of your forklift, simply merge all previous 3 indicators. How to calculate OEE. Using OEE is not an absolute measure; it can break down in various areas. Batch sizes and process inherent particularities can hugely affect OEE. Example Data. A simple example. If it can produces 20 units in an hour. For example, if a shift is 7 AM to 3 PM with a half hour lunch and two fifteen minute breaks, then there are 7 hours, or 420 minutes, available during that shift. 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. This factor is then: III. We want to get a complete understanding of why our production rate is in its current state. OEE (Overall Equipment Effectiveness) is a widely used and well recognised KPI (Key Performance Indicator) metric which evaluates how effectively a production line is utilised. Example Calculations for OEE. While if 5 milk bags are expired, and you are not using them then you can only make 5 cups of tea, here you are 50% efficient based on quality. Examples are hypothetical. After you calculate each of these metrics, OEE calculation is pretty straightforward: multiply availability, performance and quality. These are only some examples of bad practices in OEE calculation. May 26, 2015 . Some exclude preventive maintenance from the availability calculations, others exclude holidays others don’t. 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. The tables to the left contains an example with some data from a shift that have been used to calculate an OEE value. Example of OEE Calculations Many manufacturers are already using OEE, both as a KPI and as a catalyst for change. A real-world example is given to demonstrate the mechanics of a typical OEE calculation. To calculate OEE correctly, it is essential to have enough data for availability, performance, and quality scores. For that, we need to use the advanced version of this calculation. 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. 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. The first point is the point on the horizon.

OEE is the result of: Availability % x Performance % x Quality % Availability . How is OEE calculated? Let's say we own a button factory. 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. Enter your data into the white boxes and click the page to calculate the OEE figure. For the sake of example, let's say our equipment can produce 120 buttons per minute. The shift has two 10 minute breaks and a 5 minute clean up period. We’ll look at an OEE calculation example to explain how to calculate availability, performance and quality. It should be able to deliver specific number of units in a given time. Do the same as above to calculate the three parameters and then last calculate the total OEE number. The most widely used way to calculate OEE is calculated by multiplying three individual metrics : … There really is no point in hiding downtimes to inflate OEE numbers. Throughout this post I will be using examples. The six big losses are: 1) Breakdown 2) Changeover 3) … The OEE Calculation in 4 Steps. Advanced OEE calculation The advanced OEE calculation takes into consideration 3 factors that have a big impact on OEE. To understand the OEE it is crucial to introduce the 6 big losses. As for the 7 wastes in a process, a machine does not produce value of one of the following losses occur. 2. Examples of things that create Quality Loss include scrap and parts that need rework. Not all companies calculate OEE the same way. OEE [ OVERALL EQUIPMNT EFECTIVENESS ] #OEE | How to Calculate OEE ? Here is a hypothetical OEE calculation example: Let’s say an ice cube tray manufacturing plant adopts the Japanese practice of Kaizen - a lean philosophy of continuous improvement. Figure out the Availability component of OEE. Instead, use it as a measure of productivity that needs to be improved. 6 Big Losses. Availability is the percentage of time that a machine is available to produce during the measured period. Actually, if you ask 10 production managers how they calculate OEE, you will get 11 different answers. Know the 3 major elements of OEE. In 8-hour day, it should have the ability to produce 160 units. Master class OEE. 1. To calculate an OEE, we need a few data points. How to Calculate OEE: Formulas For Peak Performance. The second is the current position. An 8 hour shift is scheduled to produce three parts as shown in the schedule below. OEE calculation example. Example to present different types of improvement OEE Overall Equipment Effectiveness calculation Basically, any machine has a capacity. Set a target for periodic improvement, not an absolute value. 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. 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. OEE Quality is similar to First Pass Yield, ... Not part of the OEE calculation (it is part of the TEEP calculation). Continuous plants tend to be relatively straightforward for setting up an uptime measurement. OEE is a standard metric used to evaluate manufacturing performance by taking a broad view of all aspects of production.
