The first note in this approach is that variable quality characteristics are also better to consider as attribute and categorical quality characteristics. But, control charts for monitoring attribute quality characteristics in comparison to variable control charts have some disadvantages in structure which should be solved first. The second note is for monitoring attribute quality characteristics; which because of mental inspection and human judgments, have some level of vagueness and uncertainty. This research proposed a new approach to quality control, a fuzzy approach for monitoring the process when vagueness and uncertainty arise. The case study and comparison study show the proposed approach has a better performance and could detect abnormal shifts in the process, especially in small shifts and small sample size, faster than current related approaches.
