Abstract—This paper deals with the distribution network recon-figuration problem in a multi-objective scope, aiming to determine the optimal radial configuration by means of minimizing the active power losses and a set of commonly used reliability indices for-mulated with reference to the number of customers. The indices are developed in a way consistent with a mixed-integer linear pro-gramming (MILP) approach. A key contribution of the paper is the efficient implementation of the-constraint method using lexico-graphic optimization in order to solve themulti-objective optimiza-tion problem. After the Pareto efficient solution set is generated, the resulting configurations are evaluated using a backward/for-ward sweep load-flow algorithm to verify that the solutions ob-tained are both non-dominated and feasible. Since the-constraint method generates the Pareto front but does not incorporate deci-sion maker (DM) preferences, a multi-attribute decision makin
