Determining Process Capability Indices for Shirting Fabric
Öz
Organizations use process capability analysis to produce their products within specification limits for
regular manufacturing. Process capability indices, Cp (process potential indices) and Cpk (process
capability indices), are used as capability measures. In this study, process capability analysis and process
capability 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 that
identified from production manager. If the amount of wastage fabric increases, the number of unsatisfied
customers will also increase. And, this situation is caused increasing cost and decreasing competitiveness
for factory. For these reasons, Cp and Cpk indices were calculated for the textile factory. As a consequence
of this study, we discovered that the process was inadequate precautions must be undertaken to decrease
the amount of wastage fabric. Furthermore, the fabric faults which cause wastage fabric and the reasons
for the process’ inadequacies were also investigated.
