Overall Equipment Effectiveness (OEE) is one of the most important indices reflecting a degree of equipment maintenance effectiveness in industrial enterprises.
Most industrial enterprises despite of a character of their production have a problem of low effectiveness of equipment operation. The problem is characterized by occurrence of everyday losses resulting from downtime and unforeseen stoppages of equipment, speed decrease of product treatment and faulty units manufacture.
There is a technique of overall equipment effectiveness assessment which is considering the influence of the above mentioned losses and allowing to fully analyze equipment operation both at particular procedures and within a framework of the whole production cycle .
The overall equipment effectiveness is calculated by the following technique:
OEE= readiness × output × quality × 100%,
where: readiness - is a ratio of net production time of the item by an equipment to a total time of production cycle;
output - is a ratio of actual output to a scheduled production output;
quality - is a ratio of number of quality products to a total quantity of manufactured goods.
The analysis of overall equipment effectiveness assumes that factory personnel are involved in a permanent monitoring and registration of indices which reflect current equipment condition and production process. Overall equipment effectiveness is a balanced index which allows to optimize production process resulting in optimal output capacity of the equipment and high quality of the manufactured goods that is, to our opinion, of necessity to many industrial enterprises.
