[en] In this paper we introduce a fuzzy chart for variables which is used in situations
when uncertainty and randomness are combined. It is showed that the Shewhart chart’s
control limits must be adjusted in these situations. However, this chart is based on a fuzzy
acceptance region and this method arises when a decision should be made by referring to the
grade of a sample statistic belonging to the fuzzy acceptance region.
