In Problem 15.8, two logical machine groups are identified by rank order clustering. For each machine group, (a) determine the most logical sequence of machines for this data using Hollier Method 1. (b) Construct the flow diagram for the data. (c) Compute the percentage of in-sequence moves and the percentage of backtracking moves in the solution.

Problem 15.8

The following table lists the weekly quantities and routings of ten parts that are being considered for cellular manufacturing in a machine shop. Parts are identified by letters, and ma-chines are identified numerically. For the data given, (a) develop the part-machine incidence matrix, and (b) apply the rank order clustering technique to the part-machine incidence matrix to identify logical part families and machine groups.
