Cloud Reliability Evaluation for Complex Electronic Systems Based on Markov Model
Wang Jian-xin · Journal of Jilin University · 2008
The complex structure of electronic systems and the diversity of faults result in the uncertainties of system reliability evaluation.Thus we should renovate the traditional ideals on reliability.Cloud theory was developed,the concepts of cloud sets and cloud numbers were defined,and particularly the operation arithmetic among normal cloud numbers were presented.We analyze the Markov model of repairable decision-making system and give an approach to get the indices of system reliability.We set forth the qualitative evaluation of system reliability in natural language.We construct a Markov model for quantitative system reliability evaluation based on cloud numbers which reflect the parameters' uncertainties.Cloud reliability can be translated to the qualitative evaluation of system at certain confidence level through a novel approach.An example is promoted for repairable decision-making system.
