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:
To determine the production rate, we first need to calculate the total effective working time available per week. Each day has 9 hours, subtracting the half-hour lunch break and two 15-minute coffee breaks results in 1 hour of break per day. Thus, the effective working time per day is 8 hours. Over 5 days, this totals to 40 hours of effective work. Converting this to minutes gives us 40 hours * 60 minutes = 2400 minutes. With a customer demand of 120 units per week, the production rate required is 2400 minutes divided by 120 units, which results in 20 minutes per unit. Therefore, production must occur at the rate of one unit every 20 minutes to meet the demand.
its one hour break on total (30 min lunch )+2(15 min tea break )= 1 hour per day
20 minutes x unit*
20 is OK, (9 hours - (.5 hours of lunch + ,5 hours of tea break)= 8 effective hours per day. Passing to minutes = (8*60)= 2400 minutes, 2400 minutes/120 units = 20 unit x minuto.
Correction * Passing to minutes in a Week = (8*60*5days)= 2400
Considering 7.5hrs actual work, answer is 18.75 min
Is it an hour break or half an hour break? The answer doesn't make sense otherwise.
The answer doesn't add up if its an hour*
It's gotta be half-hour lunch break for the answer to make sense.
