Availability and OEE

What is Availability? In its simplest form, availability measures the uptime of a machine or process against the planned production time.  As one of the factors of Overall Equipment Efficiency (OEE), Availability is expressed as a percentage.  The uptime is calculated by taking the difference between the planned production time and total duration of the downtime events that occurred during the planned production period. We […]

Problem Solving with OEE – Measuring Success

OEE in Perspective As mentioned in our previous posts, OEE is a terrific metric for measuring and monitoring ongoing performance in your operation.  However, like many metrics, it can become the focus rather than the gage of performance it is intended to be. The objective of measuring OEE is to identify opportunities where improvements can be made or to determine whether the changes to your […]

OEE for Multiple Parts – Single Machine (Multipart Processes)

How to Calculate OEE for Single Machine and Multiple Parts. Flexible manufacturing provides the advantage of producing many different parts on the same piece of equipment.  The same is true for processes such as stamping presses, molding machines, or machining operations. The first question most often asked is, “How do we calculate OEE for a piece of equipment that is capable of manufacturing multiple […]

OEE and Standardized Work

Overall Equipment Efficiency (OEE):  Standardized Work After you start collecting OEE data for your processes, you may notice significant variance between departments, shifts, and even employees performing the work.  Of the many aspects that you will be inclined to investigate, standardized work should be one of them. Making sure that all employees are executing a process or sequence of processes […]

LEAN Environment: Waste Management and OEE

In recent years much emphasis has been placed on the state of our environment and LEAN can help our cause.  If we consider just how much energy and resources are consumed due to inefficiency and waste.  OEE is a measure of how effectively time is used as a resource; however, it does not necessarily reflect the waste that is created in […]

Practical OEE – How To Calculate and Use Weighted OEE

We have presented the methods of calculating OEE for a process and also demonstrated how weighted OEE is calculated for multiple processes.  Our next challenge is to determine how this data can be used to make sure we are targeting the right processes for improvement. Over the next few posts, we will show you how to calculate weighted OEE factors for each process.  […]

Weighted OEE: How To Calculate Total Plant OEE

In this post we will present a simple method to calculate a truly weighted OEE, including weighted factors Availability, Performance, and Quality. The QUICK weighted OEE method: Recalling our original definition of OEE, we are measuring how effectively our planned production time (net available time) is used to make a quality (saleable) product.  The weighted OEE then is the total time […]

How to Calculate OEE – The Real OEE Formula with Examples

A lot of time and effort is wasted collecting and analyzing data and the results.  Fortunately, Overall Equipment Effectiveness, or OEE, is one of those metrics that is easily calculated and can be applied to any process, department, or the entire organization. We have created  a number of Excel spreadsheets that are immediately available from our FREE Downloads page or from the […]
