Leakage optimization of water distribution networks by pressure control
Köker Gökgöl, Ezgi; Altan, Tomris Elvan; Department of Civil Engineering (2018)
Excess water losses from drinking water distribution network is a serious problem in many countries all over the world including Turkey where total water losses is around 40% of the distributed water. Total water losses are divided into two parts namely (i) apparent or commercial water loss and (ii) real or physical water loss. Apparent water loss is from sources such as illegal water usage (water theft), inaccuracy in customer water meters, and meter reading handling errors. Real water loss is from sources...
Rehabilitation studies about storage tanks: a case study
Çağlar, Meriç; Merzi, Nuri; Department of Civil Engineering (2015)
One of the most important factors, while designing a water distribution system, is the storage tank capacity in terms of costs. When the storage tank volume is increased, more water can be stored, the water distribution system works more efficiently, and energy costs can be decreased. Population growth, interest rate, the cost of the water distribution system elements and energy prices have major effects on the storage tank capacity. The software model of the study area, N8.3, was optimized, and the daily e...
Design of looped water distribution networks using a heuristic approach
Ateş, Halil İbrahim; Merzi, Nuri.; Department of Civil Engineering (2019)
This study aims to design pipe diameters of a water distribution network using a heuristic approach algorithm. The heuristic approach algorithm aims to maximize the reliability of the network while minimizing the total cost of the water distribution network, which is a multi-objective optimization problem. In a water distribution network, the resilience index is defined as network reliability (Todini, 2000). The cost of the water distribution network is the total cost of the network pipes. In this heuristic...
Optimization of water distribution networks using mixed-integer linear programming
Uzun, Eren; Altan Sakarya, Ayşe Burcu; Department of Civil Engineering (2016)
The present study aims to discuss the advantages and disadvantages of the design of water distribution networks by making use of mixed integer linear programming. The developed optimization algorithm considers the minimization of the total cost as the objective function. The total cost of water distribution network is defined as cost of pipes, reservoirs and pumps. Nodal demands, nodal pressure limits and pipe velocity limits are satisfied while optimizing the network. Energy equation is the equality constr...
Optimization of water distribution networks using genetic algorithm
Güç, Gerçek; Merzi, Nuri; Department of Civil Engineering (2006)
This study gives a description about the development of a computer model, RealPipe, which relates genetic algorithm (GA) to the well known problem of least-cost design of water distribution network. GA methodology is an evolutionary process, basically imitating evolution process of nature. GA is essentially an efficient search method basically for nonlinear optimization cases. The genetic operations take place within the population of chromosomes. By means of various operators, the genetic knowledge in chro...
