Error in determining the amount of the purchase of certain goods often cause the goods piled up in warehouses for long periods, resulting in the quality of goods into menuran and will suffer losses due to storage of goods that are not optimal.

These problems can be solved by determining the groups of goods, defined by the midpoint amount of random stuff, so we get the patterns corresponding categories, based on criteria set forth by the PT.
