Quizplus · Accepted Answer

The M/D/1 model with infinite capacity queue is suitable for modeling a process of washing a car in an automatic car wash, where customers (cars) arrive randomly (Poisson distribution) and the service time (washing time) is exponentially distributed. The model assumes a single server (operator) and a queue with infinite capacity (no limit on the number of cars that can wait in line). The other options are not appropriate for this model.
