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...

Process capability indices (PCIs) can be viewed as effective and excellent means of measuring product quality and performance, but they are not sufficient for evaluating an entire product with multiple characteristics. [Chen, K.S., Huang, M.L., Li, R.K., 2001. Process capability analysis for an entire product. International Journal of Production Research 39(17), 4077–4087] proposed the process ...

To solve the problem that process capability optimization in multistage manufacturing processes has not been studied so much. Firstly, a multistage manufacturing process quality variation model is built to analyze the impaction of each stage quality on process capability. Then, a multistage manufacturing process capability analysis method with “Costutility ratio” is proposed to prioritize proce...
