Process capability indices PCIs aim to quantify the capability of a process of quality characteristic X tomeet some specifications that are related to ameasurable characteristic of its produced items. One such quality characteristic is life time of items. The specifications are determined through the lower specification limit L , the upper specification limit U , and the target value T . Maiti ...

Process Capability Indices (PCIs) are appropriate tools in order to measure the inherent capability of a process. In statistical process control, there are some uncertainties in data, such as uncertain specification limits and data. In these cases, fuzzy logic can be employed to manage the uncertainties. There are some researches about fuzzy process capability indices and in this paper; we pres...

Statistical Process Control (SPC) methods can significantly increase organizational efficiency if appropriately used. The primary goal of process capability studies is to obtain critical information about processes to render them even more effective. This paper proposes a comprehensive framework for proper implementation of SPC studies, including the design of the sampling procedure and interva...
