Abstract: “Design of water tanks is a specialized field, which requires experience and sound knowledge of engineering methodologies. Economy and Cost analysis of water tanks also become important especially in case of large capacity water tanks. This research paper presents an algorithm to optimize the tank design and the construction cost for a given volume of water tank using Genetic Algorithm (GA). Genetic Algorithm proves to be an efficient search algorithm to optimize design and cost of water tanks. Genetic Algorithm chooses a proper ratio of radius to height and the cost can be reduced by 20%. Parametric study has also been carried out to study the effect of various GA parameters on the optimized cost of construction”
