(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:

Explanation / Answer

The precedence diagram of activities as follows :

                                                                                                                       A

                                         B

                                                      C

                                                                                                                         D

                                                                                                                         E

Cycle time for production of PDA ( @ 170 per hour ) = 3600 / 170 = 21.18 seconds ( rounded to 2 decimal places )

Total duration of all tasks A Through E = 11 + 15 + 7 + 5 + 20 seconds = 58 seconds

Minimum number of workstations = Total duration of all tasks / Cycle time = 58 / 21.18 = 2.738 ( 3 rounded to next higher whole number )

Tasks are assigned to workstations in such a way so that total duration of tasks under any workstation shall not exceed cycle time of 21.18 seconds

Accordingly assignment of tasks as follows:
