Abstract: |
In this study, we process the quality of the product characteristics for unilateral specification, Many industrial products can be characterized as bigger-the-best type or smaller-the-best type. Quality characteristics and process yields of unilateral or bilateral specification products can be evaluated by using process capability indices. Process capability indices Cpl or, Cpu are utilized to evaluate quality characteristics and process yields of unilateral and bilateral specification products due to the fact that the formulas for these indices are easy to understand and straightforward to apply. In this paper, a method to incorporate the fuzzy inference with process capability indices in the quality characteristics assessments is presented. Therefore, this paper will be combined with statistical and fuzzy inference square test method to assess whether the process capability requirements to meet product specifications.
