© 2023 Elsevier LtdThis work presents a bi-objective time-dependent vehicle routing problem with delivery failure probabilities (TDVRPDFP). Two objectives are jointly minimized: operational costs and delivery failure rates. Both travel times and costs, as well as the probabilities of delivery …
This article introduces a new algorithm for finding feasible or makespan-optimal solutions of Traveling Salesman Problems with Time Windows (TSPTWs) and Time-Dependent TSPTWs (TDTSPTWs). The algorithm starts from a sequence of visits of the customers involved in the problem, uses …
Hazardous material transportation is an integral part of industries that pose significant risks. Hazardous material transportation risk of is proportional to the volume of materials transferred, the length of the link, and the population density, which varies over time. By …
This paper studies a time-dependent green vehicle routing problem (TDGVRP) with the consideration of traffic congestion. In this work, the objective is to design the vehicle scheduling plan, with the goal of reducing carbon emissions, which has a positive linear …
Many companies that conduct a perishable product delivery face a practical problem when an increasingly congested road setting exists. An inappropriate routing scheme not only leads to higher delivery costs but also results in customers’ dissatisfaction. The previous literature paid …
Logistics enterprises are moving towards high efficiency and green. As an emerging technology, unmanned aerial vehicle (UAV, also known as drone) is very useful to cope with flexible and fast delivery. Electric vehicles (EVs), as new energy vehicles, are the …
Urban on-demand transportation services are booming in both passenger transportation and the transportation of goods. The types of service differ in timeliness and compensation and, until now, providers operate larger fleets separately for each type of service. While this may …
In developing countries, 40 percent of fresh fruits and vegetables are generally transported through nonrefrigerated vehicles and perishes before use, and wholesalers lose potential profits due to item rot. Here, a wholesaler’s conveyance with fresh goods starts from a depot …
In recent years, reducing emissions has been important for mitigating global warming and the effects of traffic congestion. As a variant of the green vehicle routing problem (GVRP), the time-dependent GVRP with time windows (TDGVRPTW) accounts for both time-dependent travel …
Motivated by rising concerns regarding global warming and traffic congestion effects, we study the time-dependent green vehicle routing problem with time windows (TDGVRPTW), aiming to minimize carbon emissions. The TDGVRPTW is a variant of the time-dependent vehicle routing problem (TDVRP) …
