Overall Equipment Effectiveness (OEE)

Not at all my field, so apologies in advance if I am way off target here.
I'd think you need to measure the utilisation rate of the machines...are they running all day? How is work scheduled into them. My guess is that observation and measurement is the place to start...maybe later some software to help present the information....

Statistics and presentation is no good without data....

Since this directive is coming from top management, I would presume that they want to see effectiveness in terms of $$$. Try gathering data to determine a cost per hour to operate each machine (raw material, labor, maintenance, utilities, etc...) and compare that to value of goods produced per hour. That should give management a "bang for the buck" scale to look at. Don't know of any freeware that may help with this...good luck.

Check out these websites, then google "Overall Equipment Effectiveness (OEE)"

You will find all the answers you need.

You may be able use a PM software program that has the capability to report on utilization rate, failure costs, down time costs, et al. We use a program called "Smart Maintenance" which gives us the most bang for the buck. You can go to "smartwaregroup.com" and download a free copy of the program to play with it and see if it will do what you need to do. There are plenty of other PM packages out there that may also do what you need. Good luck!

http://www.oee.com/ I hope this link help you in clarify more about OEE.

First have a look at youtube

In Swedish http://www.youtube.com/watch?v=tS179JWrsMU

or English infomration http://www.youtube.com/watch?v=eI388V_xhws&feature=related

From my part It´s part of TPS (Toyota Production System), LEAN

A lot of "companys doing computer data solutions" CMMS system have solutions but is not implemented in the system.

First get knollige of what OEE is.

OEE is the percentage of the time that a machine is producing "sel-able" parts at the "standard" rate (or std UPH). There are two ways to detemine OEE, depending on how you want to use the information:

1- simple: calculate how many parts the machine is capable of producing in one week (168 hours) at the standard rate. For example, if the standard rate is 1 part per hour, then the machine can make 168 parts in one week. Then compare that with the actual number os parts made duing one week. OEE will be the ratio of these two. In the above example, if the machine actually produced 80 parts in one week, then OEE=80/186.

This method will quickly tell you how productive your machine is. However, it will not tell you "where" you have opportunities for improvement. For that you need to use a detailed method as below:

2- OEE = Availablity x Utilization x speed efficiency x rate of quality

Among these 4 factors, the lower number can be the place you need to focus.

hope this helps

Hi,

Check out the following links, they will definitely help you (as they also helped me to track OEE and Downtime in my yogurt factory).

There may be an accepted meaning to this question of what is the OEE, but if somebody asked me that I would interpret it as what is state of the art possible vs what we have today....If there's a new machine that can produce widgets twice as fast as the one you now have, then I would say the overall effectiveness is 50% at this time....It's the percentage of what is known to be possible vs what is in current use...The next question is then logically, what is the cost, as stated in payback time....ie: We are at 50% OEE, and have a five year break even cost of upgrade...including down time and installation costs....with a $2 million required expenditure...

Then again it could mean how much more capacity could be squeezed out of the existing infrastructure...IE: We are operating at 50% of full tilt boogie...cost of FTB would require hiring 2nd shift and associated costs...
