Combining the engineering characteristic and the theory of Markov chain, this paper inferred the forecast model of fuzzy Markov chain, which had the fuzzy division of conditions and characteristics of no following effects in the main.

By establishing the prediction model for deterioration of reinforced concrete bridge based on the fuzzy Markov Chain,this paper expatiates the classification of deterioration grades of bridge structure and determination methods for fuzzy deterioration states.

The network throughput and average delay were investigated by numerical analysis and simulation experiments through discrete time Markov model.

Using the frequency of oligonucleotide to derive thetransition probability matrix for the sequence reconstruction,Markov chain model isa classical numerical simulation method of CGR and has the character of rapid calcu-lation, easy and high accuracy.

According to the statistic data on hazards occurred in Xinjiang line of New Eurasian Continental Bridge in recent 40 years, the number of dameged sectors in Xinjiang line is analyzed and forecasted by using fuzzy-Markovian chain forecasting method and principle.
