How to improve the OEE of a production line!

Nowadays, the match among companies is playing not through the best technology used to produce a product but through the EFFICIENCY of the line, thus produce more pieces in less time.

An index that proves the quality of a line is the OEE.

In the following picture, we can see what elements influence the OEE:

From the picture above we see that having an established time to produce, what decrease this time determines losses.
Improving this indicator implies improving efficiency and effectiveness, with a consequent better use of available resources and therefore an optimization of production management and a reduction of associated costs.
It is said: "know your enemy to beat it".

The value of the OEE is fixed:

As an Industrial engineer, our Goals are:

1. Detection and analysis of data, micro and macro stop for critical machines.
2. Assessment of the impact on the OEE.
3. Identification of possible improvements.

This work has to be made in order to determine the main problems affecting the OEE and to identify the improvements to the equipment and the organization, to reduce lost times and thus increase their performance.

The main wastes we can figure out are:

Straight on what you can improve in your field and then use tools to rec them.

After time spent on the production line to rec dates, use it to recognize what could be improved. Focus on the important things that make the most important percent of losses ( PARETO docet).
