Question – a:
The activity network is:
Question – b:
Cycle time = time available/demand
Time available = 8 hours = 8*3600 seconds = 28800 seconds
Demand = 400
Cycle time = 28800/400 = 72 seconds
Minimum number of workstations = sum total of all task time/cycle time
Sum total of all task time = (50 + 40 + 20 + 45 + 20 + 25 + 10 + 35) = 245 seconds
Minimum number of workstations = 245/72 = 3.40 = 4
Answer is: 4
Question – c:
