Theres no more information provided,what are you asking for?

Answer 1

32) D

Without considering the demand, the minimum possible cycle time will be equal to highest cycle time for any task which is Task v

33) Demand = 1440 units

Time available = 8 hours or 8*60 = 480 minutes or 480*60 seconds

Cycle time = 480*60/1440 seconds = 20 seconds

Ans C

34) Minimum number of workstations = Total task time/Cycle time = (4+14+12+12+6+8)/20 = 2.8

Ans E (Workstations cannot be in decimal)

35) Workstation 1 will have u, v. As no more tasks can be added, next task will be added to Workstation 2

Workstation 2, both w and x are eligible. W will be followed by y and z. X will be followed by z alone.

So, w will be assigned first

Ans A
