The process of renewing a drivers license at the Archer County Courtho

QUESTION

The process of renewing a drivers license at the Archer County Courthouse has the follow steps: 1) a clerk fills out an application form, 2) the clerk takes a picture of the driver, 3) a typist types and processes the new license. It takes an average of five minutes to fill out an application
a. the clerks have six minutes of work to do per application, this is three minutes per clerk. The typists have seven minutes of work to do per application. This is 2.33 minutes per clerk. The typists require less time, so the clerks are the bottleneck. If we assume steady state, 60 minutes/3minutes per application = 20 applications at 100%. This is 16 applications in an hour. If the DMV just opened, the first two typists will have to twiddle their thumbs for the first six minutes and the third typist will have to be idle for the first twelve miutes. Will this change things? No, 48 minutes/2.33 = 20.6, so the typists are still ahead even if they are at 80% after they sit around for the beginning of the first

. b. this is steady state so lets see how many of each we need. 60 minutes/hour /40 applications per hour = 1.5 minutes per application this is twice what we have now at 100% efficiency or four clerks. With 80% efficiency this is 5 clerks. We need 1.5 minutes for the typists too typists = 7minutes per typist/(1.5 minutes per application*0.8efficiency) = 5.83 = six typists So, we should hire 5 clerks and six typists at 80% efficiency or 4 clerks and 5 typists at 100% efficiency.
