abstract = "In this paper it is shown that recent progress in stochastic modelling and optimization in combination with advanced computer systems has now made it possible to improve the design and the maintenance strategies for infrastructure systems. The paper concentrates on highway networks and single large bridges. united states has perhaps the largest highway networks in the world with more than 0.5 million highway bridges; see Chase, S.B. 1999. About 40% of these bridges are considered deficient and more than $50 billion is estimated needed to correct the deficiencies; see Roberts, J.E. 2001. The percentage of sub-standard bridges deemed to require urgent actions in other countries such as France (15%) and UK (20%) id also high; see Das, P.C. 1999. These figures clearly indicate that maintaining highway bridges requires more resources than usually available. ",
