Ch. 6

Using the assembly-line balancing procedure, which of the following is the theoretical minimum number of workstations if the task times for the six tasks that make up the job are 4, 6, 7, 2, 6, and 5 minutes, and the cycle time is 10 minutes?

(4 + 6 + 7 + 2 + 6 + 5) / 10 = 3

Using the assembly-line balancing procedure, which of the following is the theoretical minimum number of workstations if the task times for the eight tasks that make up the job are 7, 4, 7, 8, 9, 4, 3, and 6 minutes, and the cycle time is 8 minutes?

(7 + 4 + 7 + 8 + 9 + 4 + 3 + 6) / 8 = 6

Using the assembly-line balancing procedure, which of the following is the required cycle time if the production time in minutes per day is 1440 and the required output per day in units is 2000?

1,440 minutes / 2000 units = 0.72 minutes per unit

Using the assembly-line balancing procedure, which of the following is the required cycle time in minutes per unit if the daily production time is 480 minutes and the required daily output is 50 units?

480 minutes / 50 units = 9.6 minutes per unit

Which of these expressions is Little's Law?

All of the above A. Inventory/Flow time = Throughput rate: B. Inventory/Throughput Rate = Flow time C. Inventory = Throughput rate × Flow time D. Throughput Rate/Inventory = 1/Flow Time

You have just determined the actual number of workstations that will be used on an assembly line to be 6 using the assembly-line balancing procedure. The cycle time of the line is 5 minutes and the sum of all that tasks required on the line is 25 minutes. Which of the following is the correct value for the resulting line's efficiency?

[25 / (6 x 5)] = 0.833

You have just determined the actual number of workstations that will be used on an assembly line to be 8 using the assembly-line balancing procedure. The cycle time of the line is 10 minutes and the sum of all that tasks required on the line is 60 minutes. Which of the following is the correct value for the resulting line's efficiency?

[60 / (8 x 10)] = 0.750
