چکیده مقاله:
In this study, fuzzy multiple deferred state sampling plan is proposed based on the exponentially weighted moving average statistic when the proportion parameter is imprecise for normally distributed quality characteristics in two cases known and unknown standard deviation. The obtained results show that the proposed plan is not only an extension of the existing plan, but also is more economical than it. Also, ‎an industrial example is given to illustrate the proposed plan in real applications‎.
