Availability rate, performance index and quality rate result is the overall equipment effectiveness Seiichi Nakajima with his description of the six types of loss (six big losses) to the founding fathers of the TPM method. The overall equipment effectiveness or overall equipment effectiveness is used as a measure for assessing the species of of loss of. TPM is designed to achieve a one hundred percent availability of machines and equipment. The fundamental innovation of the TPM concept was also not only oversaw the maintenance Department for the improvement process, but rather all employees were involved in this. The overall equipment effectiveness (GAE) or English of overall equipment effectiveness (OEE) a company composed of the availability rate, the performance index and the rate of quality and is an indicator of the value of a machine or plant. These figures are influenced by the six great loss sources, which are disposed in turn represents one of tasks of TPM.
At the six Sources of loss is to 1 plant shutdowns due to faults in Storungsbedingte plant outages among the sources of loss of one of the largest present. If the system fails, a distinction is made in practice between machine-dependent and machine-independent. The machine-independent failures include missing material, tools, or even staff. All the problems that are caused by errors of the system function are among the machine-dependent failures. 2. long set-up and set-up set-up and set-up work start, when the production of a part or product is complete and ends when the required standard of quality in the production of the next product is reached. 3.
losses due to idle and short downtimes for these losses are temporary malfunctions (< 10 minutes) the cause. Though the losses are relatively easy to reproduce problems, they partially significantly affect productivity. 4. reduced speed these losses due to slow running machines or plants.
