| This thesis presents a new method for the prioritization of maintenance and repair (M&R) activities related to engineering facilities. Only M&R that can be programmed into a two to three years budgeting cycle are considered in the ranking procedure. Tasks that are of an emergency nature and that must be accomplished immediately are beyond the scope of this thesis.;The methodology is intended to assist in a rational allocation of M&R funds by generating a priority list of tasks based on component importances and conditions. The premise is that the most important component in the worst condition is given the highest priority. The methodology is then applied to embankment dams, where M&R activities are performed to prevent (1) the failure of the dam (prevention system) and (2) to maintain the ability to detect the presence or absence of undesirable condition (detection system). Both systems are treated separately, and two independent lists of prioritized activities result from the ranking procedure. The reliability of the monitoring system in detecting undesirable conditions is used to reassess the relative importance of the components of the prevention system.;Finally, the proposed methodology is applied to two embankment dams, the first one (TA-24) is operated by Hydro-Quebec, and the second one (Lewisville) by the U.S. Army Corps of Engineers. |
