Using the above data, solve the assembly-line balancing problem and calculate the efficiency of your solution. Use the longest task time for your decision criteria. (Round your answer to the nearest whole percent.)

Efficiency of line balance at cycle time_______ %

Answer 1

Cycle time = 1.8 min.

Takt time = number of minutes available / no of units to be produced

= 5x5x60 /3000 = 0.5 min.

No. of workstations needed = 1.8 /0.5 = 3.6 =4 workstations
