- The growing need for sustainable logistics solutions has led to the evolution of vehicle routing problems (VRPs) into more complex variants that address modern challenges. Among these, the Two-Echelon Electric Vehicle Routing Problem (2E-EVRP) has emerged as a significant problem variant, integrating electric vehicles (EVs) into a multi-echelon distribution system. This problem considers environmental and operational constraints such as limited battery range, charging infrastructure, and urban logistics complexities. In this report, we present a comprehensive mathematical formulation for the 2E-EVRP and its variants, which include constraints like time windows, simultaneous pickup and delivery, and partial deliveries. These formulations aim to provide a robust framework for optimizing multi-tiered distribution networks using sustainable practices. Computational experiments demonstrate the effectiveness of the proposed methods.
