Abstract

With the arrival of large real-time, time-shared systems, the requirement of system reliability has become even more demanding. The result of even a momentary system misbehavior could be catastrophic, since any disruption of service is experienced by all the users on-line at that time. Thus for real-time systems such as telephone switching systems, airline reservation systems, on-line teaching machine, etc., where numerous users are served, and critical real-time systems such as command and control, a high degree of system dependability and maintainability must be realized.
