Assess the effect of operation clustering on machine loading. Operations are assigned to specific machines, not just machine types. All part type 2 operations are assigned to one type A machine along with the first operation for part type 3. The second operation for part type 3 is assigned to the other A machine. The third operation for part type 3 is assigned to the type C machine. The first operation for part type 1 is assigned to the type C machine, the second to one type B machine, and the third to the other type C machine.
