Discrete-time Geo/Geo/1 Queue with Negative Customers and Working Breakdowns
... The concept of working breakdown introduced by Kalidass and Kasturi [9] does make sense in real life. For example, when a computer is infected by a virus, it may still be able to perform but in a slower service rate. ...
