Lean production ia a way to do more and more with less and less – less human effort, less equipment, less time, and less space – while coming closer and closer to providing customers exactly what they want and then translate this into five key principles:
Lean is founded on the concept of continuous and incremental improvements on product and process while eliminating redundant activities.
The result of building a system: increasing the efficiency and effectiveness of production processes, business processes, management processes, customer satisfaction, as well as a quick and flexible response to changes in the external environment.
The value of LEAN MANUFACTURING is created in four ways or combinations thereof:
- improving the quality of goods;
- improving the quality of service;
- reduction of consumer costs;
- reduction of cycle time (lead time (order-production-delivery)).
Overall equipment effectiveness (OEE) is a measure of how well a manufacturing operation is utilized (facilities, time and material) compared to its full potential, during the periods when it is scheduled to run. It identifies the percentage of manufacturing time that is truly productive. An OEE of 100% means that only good parts are produced (100% quality), at the maximum speed (100% performance), and without interruption (100% availability).
Measuring OEE is a manufacturing best practice. By measuring OEE and the underlying losses, important insights can be gained on how to systematically improve the manufacturing process. OEE is an effective metric for identifying losses, bench-marking progress, and improving the productivity of manufacturing equipment (i.e., eliminating waste)
