Question

A 16-15 Find a Doctor, is a small startup that helps... Answer is complete but not entirely correct. Find a Doctor, is a small startup that helps people find a physician that best meets their needs (location, insurance accepted, etc.) During a "slow" time for them, they have 7 staff members taking calls from customers. On average, one call arrives every 6 minutes (standard deviation of 6 minutes). Each staff member spends on average 19 minutes with each customer (with a standard deviation of 28.5 minutes) (Round your answer to 2 decimal places.) How long does a customer spend on average waiting on hold before they can start speaking to a representative? 0.90 minutes

Explanation / Answer

Processing time =19 min

Utilization of each staff =p/(a*m) =19/(6*7) =0.4524= 45.24%

Time in queue= (19/7)(0.45242(7+1) -1)/(1-0.4524) * [(6/6)2+(28.5/19)2]/2

Time in queue= (2.714)(0.0923)/(0.5476) * [1.625]

Time in queue=0.7434 min
