Hybrid algorithms for the vehicle routing problem with pickup and delivery and two-dimensional loading constraints

Männel, Dirk - 2017

We extend the classical Pickup and Delivery Problem (PDP) to an integrated routing and two-dimensional loading problem, called PDP with two-dimensional loading constraints (2L-PDP). A set of routes of minimum total length has to be determined such that each request is transported from a loading...

Insights on the introduction of autonomous vessels to liner shipping networks

Nguyen, Gam Thi Hong; Ruzaeva, Daria; Goez, Julio Cesar; … - In: Journal of shipping and trade 7 (2022), pp. 1-27

This article investigates economic and operational effects of introducing autonomous vessels to liner shipping networks. By the formulation of optimization models, we analyze how fleet configurations with vessels of different capacity affect the cost and service level of liner shipping networks...

Shipping optimization systems (SOS) for tramp : stochastic cargo soft time windows

El Noshokaty, Said - In: Journal of shipping and trade 6 (2021), pp. 1-19

Cargo time windows have been discussed in the shipping literature in several ways and within several contexts. One way considers the hard time windows, where a fixed date is assigned to both the open and close laycan for the cargo loading and discharging ports. According to this way, the cargo...

Truck driver scheduling with combined planning of rest periods, breaks and vehicle refueling

Bernhardt, A.; Melo, Teresa; Bousonville, Thomas; … - 2017

Fuel is one main cost driver in the road haulage sector. An analysis of diesel price variations across different European countries showed that a significant potential for cutting fuel expenditure can be found in international long-haul freight transportation. Here, truck drivers are often on...

Two mathematical formulations for the containers drayage problem with time windows

Vidović, Milorad; Nikolic, Milos; Popović, Dražen - In: The international journal of business science & applied … 7 (2012) 3, pp. 23-32

The containers drayage problem studied here arise in ISO container distribution and collecting processes, in regions which are oriented to container sea ports or inland terminals. Containers of different sizes, but mostly 20ft, and 40ft empty and/or loaded should be delivered to, or collected...
