Abstract: This study considers stochastic travel times in an electric capacited vehicle routing problem (ECVRP), where the used electric vehicles may need to visit charging stations due to their battery capacities. The main goal of the present paper is to solve a two-stage stochastic programming with recourse (SPR) model for this problem using a hybrid genetic algorithm (HGA) and a Monte Carlo sampling (MCS) procedure. To show the effectiveness of the proposed approach, the computational experiments are applied to 29 instances with up to 100 customers derived from benchmarks presented in the literature. Firstly the numerical results are compared to those found by CPLEX solver for the deterministic model, thereafter a very large number of scenarios is taken into consideration to evaluate this approach in the stochastic environment using a known probability distribution.
