Mode Failure

Considering common mode failure (CMF) in the rendering cluster systems, the availability of rendering cluster systems with the increase of cluster’s number was studied. Firstly, based on availability of system with one cluster node, system with two cluster nodes was modeled with continuous time markov chain (CTMC) model. Then, the CTMC model was extended to the case of system with three cluster nodes. Furthermore, by solving these three CTMC models, availability for different cases were numerically deduced. Additionally, during one year the unavailable time for different cases was calculated and analysis by comparison was conducted. Finally, conclusions on different cases’ advantages and disadvantages are derived thereby, which offers theoretical foundations for establishing rendering cluster systems.

Mode Failure

Common Mode Failure (CMF) analysis is an important method for evaluating the reliability, safety and risk of complex systems. As the increasing in the system complexity, the common-mode question has become an important factor for conditioning the reliability and security of the control system. Based the discussion on the concepts of CMF, this paper provided a CMF analysis method using Markov model, including the modeling and analysis process. A case study was also presented to verify the feasibility of the analysis method.
