In a workcenter, six machinists were uniquely qualified to operate any one of the five machines in the shop. The workcenter had considerable backlog, and all five machines were kept busy at all times. The one machinist not operating a machine was usually occupied doing clerical or routine maintenance work. Given the following value schedule for each machinist on each of the five machines, develop the optimal assignments. Assume only one machinist will be assigned to each machine. (Hint: Add a dummy column with zero cost values, and solve using the assignment method.)
