1. Five machines will constitute a GT cell. The fromto data for the parts processed by the machines are shown in the table below.

(a) Determine the most logical sequence of machines for this data.

(b) Construct the network diagram for the data, showing where and how many parts enter and exit the system.

(c) Compute the percentages of in-sequence moves, bypassing moves, and backtracking moves in the solution.
