The definition of the variables as given must be translated in a way that the mill operator can use. Specifically, the variables are defined as the number of standard rolls to be slit according to a given knife setting. This definition requires identifying all possible knife settings as summarized in the following table (settings1,2,and 3are given in Figure 2.9). You should convince yourself that settings4,5,and 6 are valid and that no “promising” settings have been excluded. Remember that a promising setting cannot yield a trim-loss roll of width 5 feet or larger.
