Determination of the Most Important Defect Type for an Operating Room Materials Sewing Factory Using AHP

Abstract

In this study, prioritizing defect types for a sewing factory that produces operating room materials were accomplished through Analytic Hierarchy Process (AHP). Defects types evaluated in this study are; measurement errors, false and inefficient material usage, folding defects, not producing according to orders. Criteria for faults are time, cost, quality, customer satisfaction and quality. Aggregated priority weights are computed based on geometric average of two experts’ opinions for pairwise comparisons. As a result, producing inappropriately to orders was found to be the most significant fault type having the greatest priority weight. Findings are matching the recent findings obtained through AHP and Fuzzy AHP applications for prioritizing risks for production defects.  This study, different than the traditional approach of fault types and their effects analysis, deals with defects types hierarchically as a multi criteria decision making approach. Among the criteria of time, cost, quality, customer satisfaction and quantity considered in this study, customer satisfaction was determined to be the most important criterion. This study contains potentials to be extended through the application of other multi-criteria decision making techniques.
