Time-dependent routing

Managing in real-time a vehicle routing plan with time-dependent travel times on a road network

Geographic information systems, global positioning systems, traffic flow sensors and cellular phones are sources of real-time traffic data in road networks. However, many vehicle routing algorithms do not account for this real-time information. In this paper, we consider the problem …

The aquaculture service vessel routing problem with time dependent travel times and synchronization constraints

© 2021 Elsevier LtdThis paper studies the Aquaculture Service Vessel Routing Problem (ASVRP), which is an important planning problem arising in sea-based fish farming. In the ASVRP, there is a set of fish farms located in the sea, where each …

Solving Time-Dependent Traveling Salesman Problem with Time Windows with Deep Reinforcement Learning

Traveling Salesman Problem (TSP) is a well-known NP-hard combinatorial optimization problem. Recently, many researchers have used deep reinforcement learning to solve it. However, traffic factors are rarely considered in their works, in which the traveling time between customer locations is …

A risk-constrained time-dependent cash-in-transit routing problem in multigraph under uncertainty

The Cash-in-Transit (CIT) deals with the transportation of banknotes, coins, and other valuable items. Due to the high-value density of these products, incorporating security strategies in the carrier operations is crucial. This paper proposes new CIT models involving deterministic and …

Optimizing electric vehicle routing problems with mixed backhauls and recharging strategies in multi-dimensional representation network

© 2021 Elsevier LtdElectric vehicles are environmental transportation modes that are widely applied in green logistics systems. To guarantee the energy efficiency, the impacts of customer service modes and recharging strategies need to be integrated into the optimization of electric …

Optimization of single-line bus timetables considering time-dependent travel times: A case study of Beijing, China

Bus timetables play an important role in improving the level of service and reducing operations costs of a bus transit system. Without dedicated bus lanes, bus travel times, which are important input data for bus timetabling, are usually time-dependent due …
