Executive summary
The aim of the report was to determine the consumption pattern as well as the magnitude and direction of the correlations of various inputs in the production process of aluminum grade. Effective control of inputs cost is a result of efficient analysis. Therefore, the report analyzed the electrical as well as chemical and plumbing to compare their respective amount and standard deviation. The study showed that the process produces more plumbing and chemical grade as compared to electrical aluminum grade. Again, the report probed on the appropriate purchase amount for the alumina against a set value. Statistical analysis confirmed ...
