Addressing Uncertainties in Flexible Pavement Maintenance Decisions at Project Level Using Bayesian Influence Diagrams
Bayesian influence diagrams are directed acyclic graphs used as a network representation for making decisions under uncertainty. These representation facilitate the assessment of coherent...
Inspection and M&R Decisions for Infrastructure
This paper reviews different possible mathematical formulations for a joint inspection and M&R decision-making model, having various levels of restriction and computational complexity....
Mitigation of Excessive Wastewater Infiltration/Inflow Effects for US Army Installations
Wastewater collection system on military installations require periodic maintenance and repair, and occasionally upgrading. Deterioration of wastewater systems enables the entry of extraneous...
An Overview of Markovian Models for Bridge Management Systems
The typical infrastructure maintenance decision-making environment involves multiples objectives, uncertainty, and dynamics of the most commonly used infrastructure models, which captures...
Deterioration Models for Highway Bridges
Infrastructure management, especially in case of highway bridges, need a realistic and effective deterioration model in order to provide information on the present and future condition...
The Finnish Bridge Management System
A computer-based Bridge Management system, BMS, was designed in Finland by the Finish National Road Administration (FinnRA) to assist in high level bridge policy, long-term planning and...
Fuzzy Sets Model for Evaluation of Bridge Projects
This paper presents the formulation of a computerized decision support system that would aid the bridge engineer in long range planning of bridge funding needs, specially, to select the...
An Application of Scour Hazard Analysis and Management
A phased study for the assessment of bridge scour vulnerability is presented. Its objectives are to: (a) initiate a field assessment program, (b)establish data handling capabilities, (c)...
Implementation of the Indiana Bridge Management System
Management of a bridge system involves a complex decision-making process. A comprehensive bridge management system provides a set of tools that aid this process by selecting improvement...
Establishing a HSGT System Organization
Most of the attention on High Speed Ground Transportation systems thus far has been devoted to their technological, financial and construction aspects, and this was understandable since...
Implementation and Maintenance of a TGV Line
Because of the success of the TGV in France since the opening date in 1981, SNCF plans to implement 2800 miles of new line in the next 20 years. A new line project poses two management...
The TGV Rolling Stock?Its Evolution and Capabilities
The TGV has achieved a revolution in passenger rail service in France and in Europe. The subject of this paper is the TGV rolling stock, the distribution between three generations, the...
Computerized Maintenance Planning for Agency-Managed Irrigation Systems
Computerized maintenance planning has been established to facilitate: (1) preparation of the 'Catch-Up' Maintenance Plan using the field data collected while conducting the Diagnostic...
Furrow Irrigation Education
A furrow irrigation simulation computer model based on the volume-balance method is described. The model is used to develop information on furrow system performance that can be used in...
