Reliability-based optimization of water distribution networks
The water distribution system serves as a basic necessity for society. Due to its large size and involvement of various components, it is one of the most expensive civil infrastructures and thus demands optimization. Much work has been done to reduce the distribution system cost. However, with only one objective, the obtained solutions may not be practical to implement. Thus, improving cost along with the efficiency of the network is the demand of the hour. The present work introduces a unique parameter-less methodology for generating Pareto fronts without involving the concept of non-dominance. The methodology incorporates the Jaya optimization model for a bi-objective problem, one being the reduction in network cost and the other improving the reliability index of the network. The efficiency of the proposed work is analyzed for three different benchmark problems. The Jaya technique is found to be very efficient and fast when compared with the other evolutionary technique applied for the same networks. The parameter-less nature of the Jaya technique smooths the process to a very large extent as no synchronization of algorithm parameters is required. HIGHLIGHTS Jaya algorithm is applied for the very first time to a multi-objective optimization problem in the distribution network.; A priori approach is proposed to generate a set of non-dominated solutions.; The suitability of the Normalized objective function defined in previous research is validated.; Jaya converges much faster compared to another evolutionary algorithm.; Present work results in highly reliable solutions.;
