Statistical Process Control concepts and methods have been very important in the manufacturing and
process industries. The main objective is to monitor the performance of a process over time in order for the
process to achieve a state of statistical control. So many of the quality characteristics found in these process
industries are not easily measured on a numerical scale. Quality characteristics of this type are called attribute
data. Many basic attribute control charts like, p-chart, c-chart and u-chart are readily available in this process
industry. This paper designs control chart for multiple-attribute quality characteristics. Aggregate sample quality
is estimated by using interactive weighted addition of fuzzy values assigned to each quality characteristics.
Triangular Fuzzy multinomial Control charts are drawn using Multinomial distribution using α – cuts for
variable sample sizes. The proposed method is compared and numerical example is the evidence for
improvement in the process
