Customer demand is 120 units per week. The company works on a 9-hour shift per day, 5-day per week basis. Each shift has a ½-hour lunch break and two 15-minute coffee breaks. The cycle time is 12 minutes. To meet demand, production must occur at the rate of one unit every:

Question

Quizplus · Accepted Answer

To calculate the production rate, we need to first subtract the break time from the total hours worked per day:

9 hours/day - 0.5 hour lunch break - 2 (0.25 hour coffee break) = 7 hours/day

Then, we need to calculate the total minutes of production time per day:

7 hours/day x 60 minutes/hour = 420 minutes/day

To meet demand of 120 units per week, we need to produce:

120 units/5 days = 24 units/day

To calculate the production rate, we divide the total production time by the required quantity:

420 minutes/day ÷ 24 units/day = 17.5 minutes/unit

However, this is the time required to produce one unit. The question asks for the time required to produce one unit every cycle. The cycle time is given as 12 minutes.

Therefore, our answer is:

17.5 minutes/unit + 12 minutes/unit = 29.5 minutes/unit

Rounding this up to the nearest whole number, we get 30 minutes/unit.

Thus, the closest choice is B, 20 minutes.
