Car Sharing

We want to simulate a deposit of shared cars.

• Initially we have NC cars

A new client comes every T_IN minutes

• If there are available cars, he lends one car, for a duration of T_TRAVEL minutes
• If there are no cars, he is a dissatisfied client

Compute the number of dissatisfied clients, at the end of the day, as a function of NC.

Assume:

• T_IN = 10 minutes
• T_TRAVEL = random (1 hour, 2 hours, 3 hours)

Analysis

Events:

• Client arrives
• Client returns car

World model:

• Number of total cars (constant)
• Number of available cars (current)
• Number of clients served
• Number of dissatisfied clients
