Fuentes Mariles Ingeniería risk management failure probability Structural reliability Monte Carlo simulation aleatory and epistemic uncertainty A formulation to treat aleatory and epistemic un certainties, in a separate way, on infrastructures is proposed and applied to a dam and a breakwater in Mexico. The purposeof that is to determine 2nd order bounds on the reliability estimation due to the in complete knowledge of some design parameters. These bounds provide a quantitative basis for risk management according to the risk-aversion of owners and operators of thein frastructure. Also, acceptable values of reliability, are assessed in terms of consequences costs, and an initial cost curve for a breakwater is presented, as they may contribute to enhance the decision making process.The incorporation of epistemic uncertainty makes the reliability index to become a random variable and its histogram is obtained to estimate percentiles as a means to measure a new additional room for decisions as compared to the traditionally used meanvalue of the reliability. Conservative decisions are illustrated for design and assessment of structures like a dam and a breakwater.The procedure in volves a double loop of Monte Carlo simulation and represents a basis for the optimal design and risk management of dams and breakwaters. 2008 artículo científico 1405-7743 https://www.redalyc.org/articulo.oa?id=40490305 en http://www.redalyc.org/revista.oa?id=404 Ingeniería.
