© 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 …
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) …
This paper considers an extension of classical distribution problems and introduces the time-dependent fleet size and mix multi-depot vehicle routing problem. This important class of problems finds applications in urban logistics and service design. The solution to this problem impacts …
One of the standard approaches for solving discrete optimization problems which include the aspect of time, such as the traveling salesman problem with time windows or the shortest path problem with time windows is to derive a so-called time-indexed formulation. …
© 2013 IEEE.Fleet management plays a central role in several application contexts such as distribution planning, mail delivery, garbage collection, salt gritting, field service routing. Since road congestion has a big impact on driving times, fleet management can be enhanced …
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 …
