Adequacy Analysis Over the course of an 8-hour day, 96 vehicles enter a local electronics store’s parking lot. The parking lot has 5 spaces and the average customer stays in the grocery store for 15 minutes. Calculate the probability that an incoming car will be rejected. [Solution Shown Below]                           Solution First, we need to calculate the incoming flow rate. This is done as follows: Q = 96 vehicles/ 8 hours Q = 12 vehicles/hour Since we know the average vehicle is parked for 15 minutes, or 0.25 hours, we can calculate the traffic load as follows. A = Q*T A = 12 vehicles/hour * 0.25 hours A = 3 vehicle Now that we have the traffic load, we can find the probability of rejection using the equation below. P = (AM/M!)/(1 + A + A2/2 + . . . + AM/M!) Where: P = the probability of rejection, A = the traffic load, and M = the number of parking stalls. P = (35/120)/(1 + 3 + 32/2 + 33/6 + 34/24 +35/120) P = 0.11 Each entering vehicle has an 11% chance of being rejected. As a result, the electronics store loses one out of each 10 customers entering their lot.
