Abstract

The cumulative count of a conforming (CCC) control chart is used for high quality processes.The CCC − r chart is an improvement of the CCC chart that is based on the cumulative number of items inspected until observing r non-conforming ones. This paper aims to propose a new approach for manufacturer’s decision making according to the criteria among the available options. The objective function of the proposed model is to minimize three criteria simultaneously, including expected cost per hour(C), modified producer risk (PR) and modified consumer risk (CR).the solution method for the proposed model is designed by using AHP technique and a case study is analyzed described in numerical illustration section. In addition, sensitivity analysis is performed to illustrate efficacy of the input parameters on the optimal solutions of the proposed model.
