Process capability indices are appropriate tools to measure the inherent capability of process, and it is very important for companies to evaluate and minimize their losses. Since most of process capability indices do not consider the losses, the these indices based on losses can help manufacturers to understand the real capability of their processes in order to improve them. The result of this study is a new loss-based index with more specifications such as mean-based, target- based, variation-based, bounded, and loss-based compared with other process capability indices. In order to validate...
