Question:
We installed 6 electric car charging stations at a service station located on the edge of a busy highway. It is estimated that 1,200 vehicles pass through it per hour and that around 3% will stop for recharging.
Each customer takes an average of 20 minutes to load their car, pay, and then free up the space for the next customer. If all six terminals were taken, the customer would park their car behind an occupied terminal, and wait until it was freed (the customer would not change terminals while waiting). If the 6 terminals and the 6 waiting places behind each terminal were taken, a new customer would go and charge their car at another service station.
Part 1
Calculate terminal usage, the average number of cars in the station (charging or waiting to charge), and the average time a car spends in the station.
Part 2
We would now like to reorganize the terminal space to accommodate a single queue. As a result, if all six terminals were taken, a new customer would wait in line until a terminal became available. However, the line could only accommodate a maximum of 3 automobiles.
Recalculate the use of terminals, the average number of cars in the station (charging or waiting to charge), and the average time of a car in the station.
