RISComparison of Newton-Raphson Global and Loop Algorithms for Water Distribution Network Resolution
Publisher: American Society of Civil Engineers
Abstract: This paper presents the comparison of two algorithms for water distribution network resolution in terms of computational efficiency: the Newton-Raphson Global (NR-GA) and the Newton-Raphson Loop Flows (NR-LF). Both algorithms ...
Multiobjective Optimization of Rehabilitation and Leakage Detection Scheduling in Water Distribution Systems
Publisher: American Society of Civil Engineers
Abstract: This paper presents a procedure for optimal medium-term scheduling (e.g., over a time window of 5 years) of rehabilitation and leakage detection interventions in a water distribution system given predetermined budget ...
