How to Calculate OEE for Multiple Machines in Excel

Overall equipment effectiveness (OEE) is a key metric for measuring the performance of a manufacturing operation. It is a measure of how much time a machine is actually producing good parts, and is calculated as a percentage of the following factors:

• Availability: The percentage of time that the machine is available for production.
• Performance: The percentage of time that the machine is running at its designed speed.
• Quality: The percentage of parts produced that meet specifications.

OEE is a valuable tool for identifying and addressing potential problems in a manufacturing operation. By tracking OEE over time, it is possible to see trends and identify areas where improvements can be made.

In this article, we will show you how to calculate OEE for multiple machines in Excel. We will use a simple example to illustrate the steps involved, and we will provide a template that you can use to calculate OEE for your own machines.

Calculating OEE for Multiple Machines in Excel

To calculate OEE for multiple machines in Excel, you will need the following data:

• The start and end times of each production run.
• The number of good parts produced during each run.
• The total number of parts produced during each run.

Once you have this data, you can calculate OEE using the following formula:

OEE = (A x B x C) / (D x E)

where:

• A is the availability of the machine (%).
• B is the performance of the machine (%).
• C is the quality of the parts produced (%).
• D is the total number of minutes in the production run.
• E is the total number of parts produced during the run.

For example, if a machine is available for 80% of the production run, runs at its designed speed for 90% of the time, and produces 95% good parts, its OEE would be calculated as follows:

OEE = (0.8 x 0.9 x 0.95) / (60 x 100) = 0.63

This means that the machine is producing good parts 63% of the time.

Using the OEE Template

We have provided a template that you can use to calculate OEE for your own machines. The template is available for download [here](https://www.example.com/oee-template.xlsx).

3. Subtract the total number of hours that all machines were down from the total number of hours that all machines were available.	=B2-C2	80 hours
4. Divide the total number of hours that all machines were productive by the total number of hours that all machines were available.	=B2/B10	0.8
5. Multiply the result by 100 to get the OEE as a percentage.	=B4*100	80%

Overall Equipment Effectiveness (OEE) is a measure of how well a manufacturing operation is running. It is calculated by taking the product of availability, performance, and quality. Availability is the percentage of time that a machine is available to produce output. Performance is the percentage of time that the machine is actually producing output at its designed speed. Quality is the percentage of output that is meeting specifications.

OEE is a valuable metric for manufacturers because it provides a comprehensive view of how well their operations are performing. It can be used to identify areas where improvements can be made, and to track progress over time.

In this tutorial, we will show you how to calculate OEE for multiple machines using Excel. We will provide the data requirements and calculations that you need to perform, and we will walk you through the process step-by-step.

Data Requirements

To calculate OEE for multiple machines, you will need the following data:

• The total number of hours that the machines were scheduled to run
• The total number of hours that the machines were actually running
• The total number of good units produced
• The total number of defective units produced

You can collect this data from your production records. If you do not have access to production records, you can estimate the data based on your knowledge of the process.

Calculations

To calculate OEE for multiple machines, you will need to perform the following calculations:

• Availability = (Total hours run / Total hours scheduled) * 100%
• Performance = (Good units produced / Total units produced) * 100%
• Quality = (Good units produced / Total units produced) * 100%
• OEE = Availability * Performance * Quality

Example

Let’s say that you have three machines that are scheduled to run for 8 hours each day. During the day, Machine 1 runs for 7 hours, Machine 2 runs for 6 hours, and Machine 3 runs for 5 hours. The total number of hours that the machines were scheduled to run is 8 * 3 = 24 hours. The total number of hours that the machines were actually running is 7 + 6 + 5 = 18 hours. The total number of good units produced is 100, and the total number of defective units produced is 10.

The availability of the machines is (18 / 24) * 100% = 75%. The performance of the machines is (100 / 110) * 100% = 91%. The quality of the machines is (100 / 110) * 100% = 91%. The OEE of the machines is 75% * 91% * 91% = 60%.

OEE is a valuable metric for manufacturers because it provides a comprehensive view of how well their operations are performing. It can be used to identify areas where improvements can be made, and to track progress over time.

In this tutorial, we showed you how to calculate OEE for multiple machines using Excel. We provided the data requirements and calculations that you need to perform, and we walked you through the process step-by-step.

3. Interpretation

Once you have calculated the OEE for your machines, you need to interpret the results to see what they tell you about the performance of your machines.

The OEE score is a measure of how efficiently your machines are operating. A perfect OEE score would be 100%, which means that the machine is operating at its full potential and there is no downtime. However, in reality, it is rare for a machine to achieve a perfect OEE score.

The following table provides a breakdown of the different OEE categories and what they mean:

| OEE Category | Description |
| ————- | ———– |
| Availability | The percentage of time that the machine is available to produce output. |
| Performance | The percentage of time that the machine is actually producing output. |
| Quality | The percentage of output that is defect-free. |

The overall OEE score is calculated by multiplying the availability, performance, and quality scores.

For example, if a machine has an availability score of 90%, a performance score of 80%, and a quality score of 95%, then its overall OEE score would be 68%.

The OEE score can be used to identify areas where your machines are not performing as well as they could be. For example, if a machine has a low availability score, it may be due to frequent breakdowns or maintenance issues. If a machine has a low performance score, it may be due to slow cycle times or machine downtime. If a machine has a low quality score, it may be due to defects or rework.

Once you have identified the areas where your machines are not performing as well as they could be, you can take steps to improve the OEE score. For example, you could reduce the number of breakdowns by performing preventive maintenance, you could improve the cycle times by making process improvements, or you could reduce the number of defects by implementing quality control measures.

By improving the OEE score, you can increase the productivity of your machines and improve your bottom line.

4. Improvements

The OEE score can be used to identify areas where your machines are not performing as well as they could be. By taking steps to improve the OEE score, you can increase the productivity of your machines and improve your bottom line.

Here are some specific actions you can take to improve OEE:

• Reduce downtime. Downtime is any time that the machine is not available to produce output. Downtime can be caused by a variety of factors, such as breakdowns, maintenance issues, or operator errors. To reduce downtime, you can perform preventive maintenance, implement a comprehensive maintenance plan, and train your operators on how to operate the machines properly.
• Improve efficiency. Efficiency is the percentage of time that the machine is actually producing output. Efficiency can be improved by reducing cycle times, eliminating waste, and improving the flow of materials through the production process. To improve efficiency, you can identify and eliminate bottlenecks, implement lean manufacturing principles, and optimize your production process.
• Reduce defects. Defects are any products that do not meet the required specifications. Defects can lead to rework, scrap, and lost sales. To reduce defects, you can implement quality control measures, train your operators on how to produce quality products, and use statistical process control to identify and eliminate defects.

By taking steps to improve OEE, you can increase the productivity of your machines and improve your bottom line.

The OEE score is a valuable tool for measuring the performance of your machines. By understanding the OEE score and taking steps to improve it, you can increase the productivity of your machines and improve your bottom line.
