A fuzzy decision-making framework (DMF) is combined with a hybrid genetic algorithm-linear programming (GA-LP) optimization approach to determine the best booster station network for a water distribution system. The proposed hybrid GA-LP model simultaneously optimizes two conflicting objectives; namely, minimization of total chlorine injection dosage and the number of booster stations. At the same time, residual chlorine concentrations are kept within desired limits. Adjustment of the relative importance of two conflicting objectives results in different optimal solutions. Selection of the best alternative among these optimal solutions is performed through a fuzzy multiobjective DMF. The proposed DMF allows incorporation of the decision makers' preferences into the booster station network design. In this study, three fuzzy objectives are selected based on economic, operational, and health-related concerns. The hybrid GA-LP model is applied to a case study, and results show that the proposed methodology is effective in maintaining chlorine residuals within desired limits networkwide while minimizing the total chlorine injection, and the fuzzy DMF is a useful tool for incorporating the case specific limitations into the decision process.

Impacts of physical and chemical heterogeneities on aquifer remediation design Aksoy, Ayşegül (American Society of Civil Engineers (ASCE), 2004-07-01) The impacts of physical and chemical aquifer heterogeneities on optimal remediation design, costs, and time to compliance are investigated by linking a genetic algorithm with a contaminant transport simulation model. Physical and chemical aquifer heterogeneities were grouped into three levels as follows: (1) hydraulic conductivity (K) heterogeneity only; (2) combined heterogeneity of K and the distribution coefficient (Kd); and (3) combined heterogeneity of K, Kd, and the mass transfer rate (α). Various deg...
Genetic algorithm for constrained optimization models and its application in groundwater resources management Guan, Jiabao; Kentel Erdoğan, Elçin; Aral, Mustafa M. (American Society of Civil Engineers (ASCE), 2008-01-01) Genetic algorithms (GAs) have been shown to be an efficient tool for the solution of unconstrained optimization problems. In their standard form, GA formulations are "blind" to the constraints of an optimization model when the model involves these constraints. Thus, in GA applications alternative procedures are used to satisfy the constraints of the optimization model. In this study, the method that is utilized in the Complex Algorithm to solve constrained optimization problems is abstracted to develop a re...
Optimal operation of water distribution pumps considering water quality Altan Sakarya, Ayşe Burcu (American Society of Civil Engineers (ASCE), 2000-07-01) A new methodology has been developed for determining the optimal operation of water distribution system pumps with water quality considerations. The methodology is based upon describing the operation as a discrete time optimal scheduling problem that can be used to determine the optimal operation schedules of the pumps in distribution systems. The solution methodology is based upon a mathematical programming approach resulting in a large-scale nonlinear programming problem that cannot be solved using existi...
A healthcare facility location problem for a multi -disease, multi -service environment under risk aversion Taymaz, S.; Iyigun, C.; Bayındır, Zeynep Pelin; Dellaert, N. P. (Elsevier BV, 2020-09-01) This paper presents a stochastic optimisation model for locating walk-in clinics for mobile populations in a network. The walk-in clinics ensure a continuum of care for the mobile population across the network by offering a perpetuation of services along the transportation lines, and also establishing referral systems to local healthcare facilities. The continuum of care requirements for different diseases is modelled using coverage definitions that are designed specifically to reflect the adherence protoco...
Geographic information systems (GIS) for the determination of inundation maps of Lake Mogan, Turkey Merzi, N; Aktas, MT (Informa UK Limited, 2000-09-01) The use of geographic information systems (GIS) allows for a very efficient analysis of spatial hydrologic data for water resources projects especially for water control studies. rn this respect, flood hydrographs for Mogan basin, Turkey for different durations and return periods are determined by using Soil Conservation Service (SCS) method. The basic parameter of the SCS method, curve number (CN), is evaluated by using GIS employing digital land use and hydrologic soil group data derived from analog maps....
