Four parts (A, B, C, and D) are processed through a sequence of four operations (1, 2, 3, and 4). Not all parts are processed in all operations. Part A, which has weekly quantities of 70 units, is processed through operations 1, 2, and 3 in that order. Part B, which has weekly quantities of 90 units, is processed through operations 2, 4, and 1 in that order. Part C, which has weekly quantities of 65 units, is processed through operations 3, 2, and 4 in that order. Finally, part D, which has weekly quantities of 100 units, is processed through operations 2, 1, and 4 in that order. Your task is to: (a) Draw the network diagram (b) prepare the From-To table for this work system (c) use the Hollier algorithm to determine the most logical in-line sequence of workstations in the work system (d) compute the percentage of in-sequence moves, backflow moves, and by-passing moves for the sequence.
