Hattendorff's theorem is a result in queuing theory that pertains to the analysis of single-server queues, particularly those that follow a Markovian arrival process and service time distribution. The theorem deals with the expected waiting time in the queue and helps to determine both the average number of customers in the queue and the average time a customer spends in the system.
