  Abstract

In this paper, the unified Markov modeling of hardware and software for a dual-duplex and a fail-safe AVTMR system is designed and compared for the dependability of each system. In hardware case, a failure rate is fixed to no time varying parameter. On the contrary, in software case, it is applied with the time varying parameter. Especially, the software failure rate is analyzed with G-O/NHPP and evaluated accroding to the failure factor for software failure rate variables. The reliability, availability and safety of each system are analyzed with Runge-Kunta method as a software failure rate and simulated with a unified Markov modeling method, and the dependability characteristic of each system are compared. Two systems can be applied to the optimized environment as the dependability characteristic. This kind of fault tolerant system can be applied to a high reliable communication and a life critical system.
