This paper proposes five methods for improving the quality of Pareto optimal solutions of multiobjective optimal water distributionnetwork (WDN) design problems: (1) three warm initial solution methods, (2) the postoptimization method, and (3) the guided-searchmethod. The five methods were demonstrated through resilience-based design of the Hanoi network. The guided-search method, consideringthe reasonable range of decision variables, was identified as the best method with respect to the nondomination and diversity of the obtainedPareto solutions. Then, the effect of considering known initial solutions (e.g., least-cost solutions obtained from single-objective optimaldesign) on the final Pareto solution quality was investigated using the guided-search method. Finally, the guided-search method was comparedwith five multiobjective optimization algorithms widely used in the WDN research community through the resilience-based design ofwell-known benchmark WDNs (i.e., two-loop, Hanoi, Balerma, and P-city).
