M/M/∞ QUEUE WITH IMPATIENT CUSTOMERS
In this paper we proposed an M/M/∞ queue with impatient customers. Generally, customers are impatient due to long waits in queue but in this work, we consider the case when customers are not impatient due to long waits but they are impatient due to the poor quality of service. We model and analyze...
