RISSimulation-Based Performance Assessment Framework for Optimizing Port Investment
Publisher: ASCE
Abstract: This paper demonstrated a new framework for port investment optimization that includes a three-stage process. First, a performance-based approach was applied to determine the margins of ship responses under external impacts ...
Prediction of Pipe Failure by Considering Time-Dependent Factors: Dynamic Bayesian Belief Network Model
Publisher: American Society of Civil Engineers
Abstract: The water supply system (WSS) is a lifeline of the modern city. Transmission and distribution pipes, spatially distributed components of the WSS, are most often vulnerable to failure (leakage, breakage, or burst). Many ...
Considering Soil Parameters in Prediction of Remaining Service Life of Metallic Pipes: Bayesian Belief Network Model
Publisher: American Society of Civil Engineers
Risk-Based Framework for Improving Customer Satisfaction through System Reliability in Small-Sized to Medium-Sized Water Utilities
Publisher: American Society of Civil Engineers
Abstract: Small-sized to medium-sized water utilities (SMWU) face severe challenges to maximize the customer satisfaction (CS) because of operational failures, limited trained staff, and financial issues. Conventional methods are ...
Fuzzy-Based Method to Evaluate Soil Corrosivity for Prediction of Water Main Deterioration
Publisher: American Society of Civil Engineers
Abstract: A fuzzy-based method is proposed to evaluate soil corrosivity from soil properties such as soil resistivity, pH, redox potential, sulfide content, and soil type. The fuzzy-based method considers three levels of soil ...
Management of Civil Infrastructure Systems: QFD-Based Approach
Publisher: American Society of Civil Engineers
Abstract: Infrastructure owners or management agencies have well established quality control programs with the intent of achieving safe and effective maintenance. However, consumers are becoming more involved in economic, environmental, ...
Inter-Utility Performance Benchmarking Model for Small-to-Medium-Sized Water Utilities: Aggregated Performance Indices
Publisher: American Society of Civil Engineers
Abstract: About 95% of the water supply systems in Canada are being operated by small-to-medium-sized water utilities (SMWU) serving populations less than 50,000. The representation of these utilities in National Water and Wastewater ...
Water–Energy–Carbon Nexus Modeling for Urban Water Systems: System Dynamics Approach
Publisher: American Society of Civil Engineers
Abstract: A comprehensive water-energy-carbon (WEC) nexus model for an urban water system (UWS) using system dynamics is proposed to assist municipalities, urban developers, and policy makers for neighborhood water planning and ...
Optimizing Locations for Chlorine Booster Stations in Small Water Distribution Networks
Publisher: American Society of Civil Engineers
Abstract: In this paper, an index-based approach is proposed to locate chlorine booster stations in a water distribution network (DN). Chlorination is a common practice for secondary disinfection, essential for protection against ...
