Rosenberg's goal is to produce
170
PDAs per hour.a) The cycle time for the production of a PDA =
enter your response here
seconds (round your response to two decimal places).b) The theoretical minimum number of workstations that Rosenberg can achieve in this assembly
line=enter your response here
(round 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:
