WebAbstract This paper describes methods for determining and utilizing Markov chains in the evaluation of highway bridge deterioration. Using a data base of 850 bridges in New York State, Markovian transition matrices (MTM) are first found for the overall bridge condition. WebThis study presents a Markov model for the structural deterioration of storm water pipes. The model is calibrated, using Bayesian techniques, to structural condition data from the storm water asset database of the Newcastle City Council (Australia). It is shown that the Markov model is consistent with the data. The pipe characteristics of ...

Webis assumed to satisfy the Markov property, where state Z tat time tdepends only on the previous state, Z t 1 at time t 1. This is, in fact, called the ﬁrst-order Markov model. The nth-order Markov model depends on the nprevious states. Fig. 1 shows a Bayesian network representing the ﬁrst-order HMM, where the hidden states are shaded in gray. ray rice position
