A Modified Process Capability Index Using Loss Function Concept

Process capability indices (PCIs) have been frequently employed in manufacturing organizations. In this paper, some existing PCIs are reviewed, and after that, the loss function concept is used as a practical tool for PCI. In this regard, an effective scheme for a revised PCI is presented. The preference of the revised index is presented in theory and illustrated through a numerical example. Copyright (c) 2015 John Wiley & Sons, Ltd.
