Sue Helms Appliances wants to establish an assembly line to manufacture its new product, the Micro Popcorn Popper. The goal is to produce five peppers por hour. The tasks, task times, and immediate predecessors for producing one Micro Popcom Popper are as follows: Task Listed Below 10 10 A, B B, C D, E a) The theoretical minimum number of workstations- (round your response up to the next whole number). b) The assignment of tasks to workstations should be: (Hint: Number workatations soquontially in torms of procedonce relationships and combine any applicoble tasks.)

Cycle time is maximum amount of time a product is allowed to spend at each workstation so that the production rate is achieved.
Cycle time = Available time/demand rate = TAKT time = 1.5 mins/unit
Demand rate = 5 per hour
Available time = 1 hour = 60 minutes per hour
Cycle time = 60 minutes per hour/5 units per hour = 12 minutes per hour
Cycle time = 12 minutes per hour
Total Task Time = ?Ti = 53 minutes
a)
Theoretical Minimum number of workers required = Total work time/CT = ?Ti/CT = 53/12 = 4.42
Minimum number of work station required = 4.42 work stations
Adjusted number of W/S = 5 work stations

Actual number of workstation required is 5, whereas theoretical number of workstation is 4.
ANS for (7) No
c)
Efficiency = Total work content/(# of workstation x cycle time) x 100
Efficiency = 53/(5 x 12) x 100
Efficiency = 88.33 %
