A new capability index based on the real defectives rate of the process.

What is it about?

In the present paper is proposed a new capability index based on the real defectives rate of the process, which is that produced taking into account also all the system periods. Therefore such new index is able to estimate the real process capability level. Finally, in order to compare the new index to the conventional Cp capability index, a numerical comparison study related to a process capability analysis is carried out and the related practical considerations are given
