A Set of States (S). Probability Transition Matrix (P).

14 Markov Chain Let s study the change of condition states of a system within a set of condition states S. A Markov chain is a sequence of random discrete variables having the property that, given knowledge of the present, the past is irrelevant for predicting the future. In other words, { } n+ = j = =... n = n n = i Pr X s X s X s X s X s { } n+ j n i = Pr X = s X = s

43 CONCLUSION Predicting the deterioration process of road infrastructure is always the significant and challenging task for road management agencies to ensure the effectiveness of the maintenance and management work. Using prediction model based upon Markov chain of stochastic process, future condition state of roads are definitely determined. Consequently, the most proper scenario of road maintenance should be established. Given the required quality of the roads, the maintenance scenario Will be presentated of minimum in life Life cycle Cycle cost Cost should Analysis be specified. (). Otherwise, given the limit allocated budget, by using prediction model the maintenance scenario of highest quality gained also is pointed out.
