The risk assessment approach is useful for monitoring and supervisory control because it provides distribution operator with the capability to quantify the tradeoff between reliability and economic performance. The risk assessment determines the likelihood of something going wrong in a distribution network through the failure probability metric. To deal with the massive variety of information required...
In recent years, China is vulnerable to flood hazard which caused enormous economic loss and flood control has become the national focus. However, as the rapid economic development, climate change and frequent human activities, the only application of engineering measures against flood cannot meet the challenge of flood control anymore. As a result, the non-engineering measurements must be developed...
The occurrence of Geotechnical catastrophe caused by high slope has been a serious constraint on economic development of the mountainous city. A mountainous city high slope risk management information system based on the GIS is established by integrating the mountainous city high slope hazards risk evaluation model with graphic processing and spatial analysis function of the GIS together. The system...
A software system was developed for the integrated risk assessment of chemical places. The system was based on several types of models centered on indicator analysis. Being the groundwork of the system, management of cases (historical accidents) and chemicals is introduced in detail. The former is data source from where indicators are built with some data-mining methods such as analytical hierarchy...
PCCP is usually used throughout many water and wastewater utilities as critical mains with high flow rates, sudden failures can have significant negative consequences. The world has experienced a number of failures of prestressing concrete cylinder pipe (PCCP) lines and as a result during the past ten years, much attention has been focused on reliably assessing the condition of PCCP mains. In this...
