Five parts (A, B, C, D, and E) are processed through a sequence of five operations (1, 2, 3, 4, and 5). Not all parts are processed in all operations. Part A, which has daily quantities of 8 units, is processed through operations 2, 3, 5, and 4 in that order. Part B, which has daily quantities of 10 units, is processed through operations 1, 2, and 3 in that order. Part C, which has daily quantities of 4 units, is processed through operations 3, 2, and 4 in that order. Part D, which has daily quantities of 3 units, is processed through operations 1, 2, 4, and 5 in that order. Finally, part E, which has daily quantities of 5 units, is processed through operations 1, 2, and 3 in that order.
