Statistical Process Control: A Case-Study on Haleeb Foods Ltd., Lahore.

Abstract

The process capability of Tetra Pack Machines of Haleeb Foods Limited (HFL) is analyzed. The process capability ratios Cp, Cpu, Cpl and Cpk are used as capability indices. In general, process capability position of machines is good. But the results have pointed out high variability points, as well. The process mean goes out of speciation limits at least once in a week, for every machine. The whole process goes out of specification limits once in a week, only for 2 machines. It should be taken care off. The HFL is suggested to introduce high technology to reduce the variability and insure the process capability.
