© 2024Blood plays a critical role in humanitarian logistics, and it is essential to create an appropriate blood type supply chain (BTSC) network to manage the supply and demand of blood components efficiently, especially during crises. This paper formulates a …
© 2023 Elsevier LtdThe design of synchronized services is of great significance to the development of intermodal transportation. In the planning of Air and High-Speed Railway (HSR) integration services (AHIS), the operators aim to synchronize flight and train schedules and …
© 2023 The Author(s)Fisheries face challenges in improving efficiency and reducing their emission footprint and operating costs. Decision support systems offer an opportunity to tackle such challenges. This study focuses on the dynamic fishing routing problem (DFRP) of a tuna …
© 2023 Elsevier LtdAs an emerging and sustainable technology, electric vehicles (EVs) are becoming increasingly popular in the transportation system. However, they still have limitations in terms of energy capacity and high consumption. By implementing flexible scheduling for EV routings, …
© 2013 IEEE.This article introduces, models, and solves the time-dependent in-building delivery problem in last-mile logistics. It determines efficient travel sequences for a worker (e.g., delivery person, deliveryman, mailman, agent) who delivers goods or provides services directly to customers located …
© 2013 IEEE.The time-dependent green vehicle routing problem with time windows is a further deepening of the research on vehicle routing problems with time windows. Its simultaneous consideration of vehicle transportation time, carbon emissions, and customer satisfaction under time-dependent variables …
Abstract To address the realistic problem of seriously reducing distribution efficiency and increasing distribution cost caused by road traffic congestion, this paper constructs a time-dependent speed describing vehicle travel speed and road traffic flow by simulating the change of urban …
© 2023 Elsevier LtdThe time-dependent pollution routing problem (TDPRP) extends the pollution routing problem (PRP) cause it captures traffic congestion at peak periods in urban transportation. It concerns planning a fleet of homogeneous vehicles to serve all customers, jointly deciding …
© 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 …
