Apply the rank $-$ order clustering technique to the part $-$ machine incidence matrix in the following table to identify logical part families and machine groups. Parts are identified by letters, and machines are identified numerically:

$\backslash$ table $[[,,,,,,$ Part,,,, $],[,,$ A $,$ B $,$ C $,$ D $,E,F,$ G $,H,1],[\frac{D_1^n}{\frac{c}{5}},1,1,2,,1,,8,3,,1],[2,,1,,1,1,,1,2,],[3,,?,1,1,1,4,,1,],[4,,1,2,1,,1,1,,],[5,,8,1,1,,,,1,],[7,1,,2,1,,,,,],[8,,,1,,1,,,,]]$
