Answer :
To calculate the number of machines that the operator can service based on the lowest TEC (Total Elapsed Cycle) time, we need to consider the time it takes to service each machine, walk to the next machine, and the running time of each machine.
First, let's calculate the total time for servicing and walking to a machine. The operator takes 1.70 minutes to service a machine and 0.2 minutes to walk to the next machine. Therefore, the total time for one cycle is 1.70 + 0.2 = 1.90 minutes.
Next, let's calculate the total time for each machine cycle, including the running time of the machine. Each machine runs automatically for 2 minutes, so the total cycle time for each machine is 1.90 + 2 = 3.90 minutes.
To find the number of machines the operator can service based on the lowest TEC, we divide the total available time by the total cycle time for each machine.
Let's assume the operator works for 60 minutes (1 hour). In 60 minutes, there are 60 / 3.90 = 15.38 machine cycles. Since we can't have a fraction of a machine, we need to round down to the nearest whole number.
Therefore, the operator can service a maximum of 15 machines based on the lowest TEC.
Based on the lowest TEC, the operator can service a maximum of 15 machines. Therefore, the correct answer is not provided in the options given (A. 2, B. 4, C. 6, D. 5, E. 3).
