Question

Fred's Quick Wheels has one bay dedicated to alignments. The garage normally is open only on weekdays from 7 a.m. to 6 p.m. and on Saturdays from 7 a.m. to noon. An alignment and balancing takes an average of 50 minutes to complete, although Fred charges customers for 2 hours according to a nationally published mechanic’s labor-standard manual. During March, the height of pothole season, Fred's is open from 7 a.m. to 9 p.m. on weekdays and 7 a.m. to 5 p.m. on Saturday.

1.Caclulate Fred's Quick Wheels' capacity in alignments per week using their regular shop open hours.

2.Calculate Fred's capacity in alignments per week during the height of pothole season with their extended hours.

3.During the second week of March Fred's Quick Wheels completed 90 alignments in their single bay. Calculate the utilization of the bay. Enter your answer as a decimal to three places

Explanation / Answer

Average alignment time taken = 50 minutes

Time of operations during weekdays = 11 hours x 5 days = 660 x 5 = 3300 minutes

Time of operations during Saturdays = 5 hours = 300 minutes

Time of operations during a week = 3300 + 300 = 3600 minutes

Capacity = 3600 / 50 = 72 alignments per week

Time of operations during height of potholes season weekdays = 14 hrs x 5 days = 840 x 5 = 4200 mins

Time of operations during height of potholes season Saturdays = 10 hrs = 600 minutes

Time of operations during one week of height of potholes season = 4200 + 600 = 4800 minutes

Capacity = 4800 / 50 = 96 alignments

Utilization of bay in the second week of March = 90 / 96 = 0.9375 or 93.75%
