Locker location for ecommerce in Paraguay. A multi-objective approach

In this paper, a multi-objective mathematical model is presented for the parcel distribution problem in the last mile, using properly located lockers considering four objectives: (1) initial investment, (2) monthly income, (3) satisfied customers and (4) unsatisfied demand. In order to solve the mathematical model computationally, two alternatives are implemented: an exhaustive search method and the multi-objective evolutionary algorithm NSGA-II. Simulations are presented for the city of Asuncion Paraguay, validating the model.
