Using the assembly-line balancing procedure, which of the following is the theoretical minimum number of workstations? the task times for the eight tasks that make up the job are 8, 4, 7, 9, 10, 14, 12, and 8 minutes, and the cycle time is 8 minutes.

the theoretical minimum number of workstations is 9.

Step-by-step explanation:

to determine the theoretical minimum number of workstations we use the formula below:

Number of workstations = sum of total task time / cycle time

Given information :

Task times =  8, 4, 7, 9, 10, 14, 12, and 8 minutes

sum of total task time = 8+4+7+9+10+14+12+8

                                  = 72 minutes

cycle time = 8 minutes

Thus,

Number of workstations = 72 minutes / 8 minutes

                                      = 9
