WHY FUZZY QUALITY?
Authors: Abbas Parchami, Bahram Sadeghpour, Gildeh Mashaallah Mashinchi
Abstract: Such as other statistical problems, we may confront with uncertain and fuzzy concepts in quality control. One particular case in process capability analysis is a situation in which specification limits are two fuzzy sets. In such a uncertain and vague environment, the produced product is not qualified with a two-valued Boolean view, but to some degree depending on the decision-maker strictness and the quality level of the produced product. This matter can be cause to a rational decision-making on the quality of the production line. First, a comprehensive approach is presented in this paper for modeling the fuzzy quality concept. Then, motivations and advantages of applying this flexible approach instead of using classical quality are mentioned.
Keywords: fuzzy quality, process capability index, quality control chart, manufacturing process
