Stanford Rosenberg Computing wants to establish an assembly line for producing a new product, the Personal Digital Assistant POA). The taska, tak times, and immediate predecessors for the tasks are as folow Task Time Immediate Predecessor A B D 12 14 8 4 18 B,C D Rosenberg's goal is to produce 180 PDAs per hour. a) The cycle time for the production of a PDA-seconds (round your response to two decimal places) b) The theoretical minimum number of workstations that Rosenberg can achieve in this sembly in fround your response up to the next whole number). c.) For one to assign the tasks to the actual workstations and be able to use the theoretical minimum number, the activity angement should be Workstation Tasks Assigned to Workstation B 3 Were you able to assign all the tasks to the theoretical minimum number of workstations
