Determining Process Capability Indices for Shirting Fabric

Abstract

Organizations use process capability analysis to produce their products within specification limits forregular manufacturing. Process capability indices, Cp (process potential indices) and Cpk (processcapability indices), are used as capability measures. In this study, process capability analysis and processcapability indices are discussed in the context of a textile factory that produces shirting fabrics in Turkey.In this factory, it is desired that the amount of wastage fabric does not exceed the upper limit thatidentified from production manager. If the amount of wastage fabric increases, the number of unsatisfiedcustomers will also increase. And, this situation is caused increasing cost and decreasing competitivenessfor factory. For these reasons, Cp and Cpk indices were calculated for the textile factory. As a consequenceof this study, we discovered that the process was inadequate precautions must be undertaken to decreasethe amount of wastage fabric. Furthermore, the fabric faults which cause wastage fabric and the reasonsfor the process’ inadequacies were also investigated.
