چکیده

Abstract. In this research, reliability indicators of water distribution networks were evaluated under pipe failure conditions. The case studies included two benchmark and one real-life network in Iran with more hydraulic constraints. Some important presented, such as resilience index, resilience, modified minimum surplus head index. GANetXL was used to do the one-objective two-objective optimization previously mentioned order not only minimize cost but also maximize indicators. Moreover, results a statistical analysis for each determine sensitive pipes that most probability. is an tool Microsoft Excel environment works based on genetic algorithm. has capability being linked EPANET (hydraulic simulation software). obtained clearly showed index poor performance when compared other indexes conditions, especially include small diameters. It if optimized terms cost, then there would be unacceptable pressure drop at some nodes failure.

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Reliability Assessment of Water Distribution Networks Considering Mechanical-Hydraulic Behavior Using Informational Entropy

This paper presents a new weighted entropy-based measure for assessing reliability of water distribution networks. The proposed methodology considers both of mechanical uncertainties (probability of pipe failure) and uncertainties due to hydraulic parameters (flow in pipe) simultaneously. In this methodology a penalty function is defined for different links of the network based on their probabi...

Optimizing Intermittent Water Supply in Urban Pipe Distribution Networks

In many urban areas of the developing world, piped water is supplied only intermittently, as valves direct water to different parts of the water distribution system at different times. The flow is transient, and may transition between free-surface and pressurized, resulting in complex dynamical features with important consequences for water suppliers and users. Here, we develop a computational ...
