Aiming at the multi-depot heterogeneous vehicle routing problem under time-dependent road network and soft time window, considering fixed cost, window penalty cost transportation an optimization model of is established with objective minimizing distribution cost. According to characteristics problem, a hybrid genetic algorithm variable neighborhood search temporal–spatial distance designed. Cus...

Abstract Autonomous vehicles create new opportunities as well challenges to dynamic vehicle routing. The introduction of autonomous information-collecting agents results in scenarios, where nodes are found by proximity. This paper presents a novel vehicle-routing problem variant with proximity-dependent nodes. Here, we introduced variable, detectability , which determines whether proximal node ...

over the two last decades, distribution companies have been aware of the importance of paying attention to the all aspects of a distribution system simultaneously to be successful in the global market. these aspects are the economic, the environmental, the social and the safety aspects. in the vehicle routing problem (vrp) literature, the economic issue has often been used, while the environmen...

One of the most important points in a supply chain is customer-driven modeling, which reduces the bullwhip effect in the supply chain, as well as the costs of investment on the inventory and efficient transshipment of the products. Their homogeneity is reflected in the Inventory Routing Problem, which is a combination of distribution and inventory management. This paper expands the classical In...
