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?

A. 0.500

B. 0.833

C. 0.973

D. 0.990

E. None of these

option (B) 0.833

Explanation:

Data provided in the question:

Actual number of workstations that will be used on an assembly line = 6

Cycle time of the line = 5 minutes

Sum of all that tasks required on the line = 25 minutes

Now,

Resulting line's Efficiency

= [ Sum of all task times ] : [ Actual number of workstations * cycle time ]

or

Resulting line's Efficiency = 25 minutes : [6 * 5 minutes]

= 0.833

Hence,

The answer is option (B) 0.833
