| Abstract | |
Nowadays, the frenetic growth of e-commerce is a well-known fact, and consequently, many companies have faced complex fulfillment challenges. Although many studies analyze shipping cost and order delivery, only a few works address the multi-echelon present in the logistics distribution of the Latin American company on which this study is based. In this work, we investigate a delivery planning problem of localities based on an e-commerce company. The main objective is to reduce transportation and delivery costs. For such, we formulated and evaluated two mathematical models (direct delivery and vehicle routing) using commercial optimization solvers. Then, a MIP-Heuristic (Proximity Search) method was developed to solve the problem more efficiently. The results show a reduction in transportation costs when routing deliveries, 82% for some instances compared to the direct delivery model. The MIP-Heuristic results showed a reduction of 22% when compared to the solver solution obtained within the one-hour time limit. Hence, the integration of middle-mile and last-mile delivery is expected to provide more efficient solutions on the e-commerce logistic supply chain, by achieving fast last-mile delivery and reducing shipping costs, and therefore contributing to the literature.
