Task Immediate Predecessor A B D E Time (sec) 12 15 8 4 20 A , D Stanford Rosenberg Computing wants to establish an assembly line for producing a new product, the Personal Digital Assistant (PDA). The tasks, task times, and immediate predecessors for the tasks are as follows: 170 Rosenberg's goal is to produce 1 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 assembly line-cround 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 assignment should be: c) For one to assign the tasks to the actual workstations and be able to use the theoretical minimum number, the activity assignment should be: Workstation # Tasks Assigned to Workstation A 2 3 Were you able to assign all the tasks to the theoretical minimum number of workstations
