What Is OEE?

  OEE  (Overall Equipment Effectiveness) reduces difficult and complex production issues into readable, well-presented, and usable information . Its measurement helps to improve your processes and can be used to monitor best practices on machines, assembly lines, and manufacturing cells. Planned production time:  To help find your planned production time you will need to know this equation;  Plant operating time - Planned shut down time = Planned production time. OEE  will look at your planned production time and measure and record overall efficiency and losses to be able to remove them once they have been recognized. Downtime loss:  This is considered to be anything that stops production for some time such as machine failure, shortages of required materials, and changeovers. Performance:  The performance covers any factors that may cause your machinery not to operate at its maximum speed or capacity. Quality:  OEE  will also consider any quality loss issues . Thi

Information Modeling As a Tool for Collaboration

  In the spirit of the upcoming holiday season , let's take a moment to examine one of the greatest and most appreciable qualities of a healthy organization: collaboration. In a world so full of information, where we are all so busy and so pressed for time, it seems collaboration has become something done more out of necessity than out of a desire for quality and efficiency. Some of this reality may be because there simply are no good tools for collaboration in the modern workplace. Sure, we have email and teleconferencing, web meetings, and text messages - but for all of our technology, our endless need to compartmentalize and segment our business processes has left us no closer to a model of organic collaboratio n than we were in the past. With relevant information stored in separate silos, decision-makers are still forced to rely on reports and statistics compiled from historical data and interpreted to support a specific agenda. There have been no truly organic means

The New OEE Impact Andon Boards for Lean Manufacturing System

 Andon can be defined as a "visual control" device that shows machine, process status, or line. Most lean manufacturing systems need this device as it is very useful to reduce production waste at all levels. By using andon boards, a company can monitor and ensure productivity easily. Manufacturing warehouses use this tool to see order status or priorities instantly even from more than 100 feet away. This device can also function as an early warning devices since audible alarms or warning messages are installed in the device. In short, it can be said that this communication tool leads to better coordination of orders, priorities, and parts in a lean manufacturing system. This good coordination finally leads to better customer service. The use of andon boards replaces the role of traditional communication tools in lean manufacturing systems. With this device, now a company doesn't need to use clipboards, whiteboards, or emails to communicate. Mostly, the boards

The Use and Abuse of OEE

 The simple answer is " Improvement ". OEE is an improvement measure and is used as part of the improvement cycle. Unfortunately, much is made of the 85% 'World Class Standard' an arbitrary target found in the original TPM literature. Not only is this target out of date (Nissan in Sunderland are running welding lines at 92-93% OEE) it gives the wrong message. A customer has no interest in your OEE - that is an internal measure, which relates to your efficiency and costs. The customer is far more interested in a measure such as On Time In Full (OTIF) ie did I get my order? Running a manufacturing business on an arbitrary efficiency measure rather than a customer satisfaction measure is a recipe for disaster. The best use of an OEE target such as 85% is to recognize that if you are reaching that level and the customer is still not getting his orders on time, then you may have a capacity constraint. OEE does not tell us if we have a problem , the customer does. Wh

The New Methodology of Design For OEE Brings System Improvements

 If you are like most organizations who are using automation for productivity OEE is a key metric in determining where improvement efforts should be focused. If most of your production steps utilize production machines then all of the OEE components apply, Availability, Performance, and Quality. With Design For Six Sigma (DFSS) most of us practitioners of Lean Six Sigma have realized the quality and cost benefits within the process of New Product Introduction. I would like to present something similar and just as beneficial which I call, Design For Overall Equipment Effectiveness or FREE. Before all of the DFSS purists get upset, I do agree the DFSS methodology can be used for machine design and some of its approach is included within FREE. The main difference is in the focus on the OEE components and an emphasis on the complete production system. So let me go on and discuss the methodology of FREE. To start let's ask some questions you might have asked yourself in the past
