| Abstract: | This paper investigates a mathematical model of an information computer network system. In this model, the system has two parts—a controller and a terminal. It is also linked with a satellite by a disk antenna. Each part has two failure modes; one is transient failure and second is latent failure. After latent failure, the terminal is recoverable, but the controller is not recoverable. The system may also fail due to a common-cause failure when it is in the normal state or in a partially normal state. Failure rates are constant and recovery rates are general. Using the regenerative point technique several measures of system effectiveness are obtained. |
