supply chain exam 2

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?

.833 [25/(6 x 5)] = 0.833

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?

6 (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 in minutes per unit if the daily production time is 480 minutes and the required daily output is 50 units?

9.6 480/50= 9.6
