Abstract: Process capability indices are appropriate tools to measure the inherent capability of a process, but most of them do not take into account the losses of a process. By integrating the Taguchi loss function and a process capability index (C_pk), a new process capability index called fuzzy Taguchi loss-based process capability index (FTPCI) was developed. Due to the definitions of a capable process or value of standard loss, the fuzzy approach to the result of the index C_pk and Taguchi losses have been proposed. In order to construct this new fuzzy process capability index, Mamdani fuzzy system consisting of the Taguchi loss and the index C_pk was employed. Finally, an example on the usage of this process capability index illustrated the results.
