OEE and Capacity Management

Capacity – Available or Required? From a scheduling perspective it is very easy to determine how much capacity (or time) will be required to manufacture a minimum quantity of parts.  However, it is not just a matter of multiplying the Standard Cycle Time by the Quantity of Parts and dividing by the part or process OEE %. As you may recall, the availability component of […]

Upcoming OEE Topics – February 2009

The following topics will be featured in an upcoming post, we’ll try to squeeze them in before February 2009 rolls off the calendar.  If you have a topic that you would like to see featured on our site, send an e-mail to LeanExecution@gmail.com. Capacity Planning with OEE:  By definition, it only makes sense to use OEE as an integral part of your […]

OEE and Morale

Is employee morale impacting your OEE?  If so, how much of a concern is it?  As we wrote in one of our recent posts,  “Perhaps the greatest “external” influence on current manufacturing operations is the rapid collapse of the automotive industry in the midst of our current economic “melt down”.  The changes in operating strategy to respond to this new crisis are bound to have an effect on OEE […]

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 […]

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 […]

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 […]

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 […]

OEE, Downtime, and TEEP

We have received several inquiries regarding equipment down time – periods of time when the machine is not scheduled to run.  We consider this to be scheduled down time or idle time and does not affect Overall Equipment Effectiveness (OEE), since no production was planned during this period. OEE measures overall equipment effectiveness during planned production or SCHEDULED up time.  Do […]
