This article shows how to calculate the yields of products which are classified by rewinding quantity into grades A, B and C and how to increase the yield of grade A. Used as the basis of calculation is the relation between (1) the statistical mean values and the standard deviation of a group of inputs during winding and (2) statistical mean values and standard deviations of final products.<br>It is difficult to lessen the standard deviation of the winding quantity of a group of inputs or Grade A in a group of outputs, but it is easy to change the mean winding quantity of a group of inputs. Therefore, by fixing the standard deviations we can formulate the relation between the yield of each grade and the winding quantity of a group of inputs and decide the most economical conditions for the rewinding process.
