Abstract Water distribution network (WDN) is an important infrastructure which suffers from failures. A risk-based decision making required for maintaining the integrity of water mains effectively. This paper presents a framework for risk assessment of pipes in a WDN for maintenance prioritization. Because pipe failure can lead to various types of consequences, a fuzzy inference system (FIS) is proposed to aggregate different consequences. The properties of algebraic connectivity (AC) from compl...

AbstractThis paper presents a method for prioritizing water mains for inspection and maintenance with consideration of municipalities with a lack of data for failure probability assessment. The met...

Unexpected pipe breaks in municipal water distribution systems may cause isolation of parts of the network or reduction of redundancy, leading to reduced system reliability. While a network with less redundancy implies less tolerance to further breaks, the isolation of nodes explicitly indicates unavailability of the system to service the nodes. This paper presents a method of measuring these topological changes using algebraic connectivity ( AC ). AC is a parameter that can be used to assess ro...

A number of burst pressure models were developed to determine the remaining strength of corroded pipelines. However, no single model has been found to be acceptable for predicting the burst pressure correctly. In this paper, the burst pressure models for corroded pipelines are revisited based on the structures of three existing models. The model parameters are re-evaluated using an optimization (differential evolution) algorithm with a database developed based on finite element (FE) analysis. A ...
