Techniques and Methods to Support Dependability
- 1.8k Downloads
In chapter seven some of the Reliability Techniques will be considered. These techniques, classified into quantitative and qualitative, are methods of analysis to evaluate the dependability parameters and the failure modes in which a realistically complex system is or could be subjected to. The techniques that will be described are Markov models. Other techniques, such as FMEA, FMECA and FTA, will be discussed in the following chapter 8. Markov models are characterized by a particular representation of Availability: a matrix in place of a single index. The matrix representation permits studying the behavior of the system, under different hypotheses, as a stochastic process, and studying its temporal evolution.
