Suppose that four machine, 1, 2, 3, and 4, belong to a GT machine cell. An analysis of 50 parts processed on these machine has been summarized in the From/To chart shown in Table 18.7. Additional information is that 50 parts enter the machine grouping at machine 3, 20 parts leave after processing at machine 1, and 30 parts leave after machine 4. Determine the most logical machine sequence using the Hollier mathod
