Little's Law: During a busy holiday season, a certain retail district has a parking problem. The rectangular district is surrounded on all four sides by a narrow road with enough room for only 80 vehicles to be circling. Inside the rectangle, along the outside edges, are rows of parking spots, totaling 200 in all. Marketing data shows that on an average 12-hour business day, 200 cars per hour approach the district seeking parking spots, and customers once parked spend on average 2 hours shopping. However, because of variability in inter-arrival and shopping times, on average 190 out of the 200 parking spots are occupied over the course of the day.
