A mathematical model of inter-terminal transportation

Tierney, Kevin; Voß, Stefan; Stahlbock, Robert - In: European Journal of Operational Research 235 (2014) 2, pp. 448-460

We present a novel integer programming model for analyzing inter-terminal transportation (ITT) in new and expanding sea …, penalized late container delivery, multiple ITT transportation modes, and port infrastructure modifications. We show that our …

A tree search procedure for the container pre-marshalling problem

Bortfeldt, Andreas; Forster, Florian - In: European Journal of Operational Research 217 (2012) 3, pp. 531-540

In the container pre-marshalling problem (CPMP) n items are given that belong to G different item groups (g=1,…,G) and that are piled up in up to S stacks with a maximum stack height H. A move can shift one item from one stack to another one. A sequence of moves of minimum length has to be...

Nominal and robust train timetabling problems

Cacchiani, Valentina; Toth, Paolo - In: European Journal of Operational Research 219 (2012) 3, pp. 727-737

In this paper we survey the main studies dealing with the train timetabling problem in its nominal and robust versions. Roughly speaking, the nominal version of the problem amounts of determining “good” timetables for a set of trains (on a railway network or on a single one-way line),...

Projection of future transport energy demand of Jordan using adaptive neuro-fuzzy technique

Al-Ghandoor, Ahmed; Samhouri, Murad; Al-Hinti, Ismael; … - In: Energy 38 (2012) 1, pp. 128-135

This paper illustrates a new approach to model and forecast the transport energy demand of Jordan based on Adaptive Neuro-Fuzzy Inference System (ANFIS) and the double exponential smoothing techniques. The ANFIS model has been developed using socio-economic and transport related indicators based...

The line planning routing game

Gattermann, Gattermann, P.; Schiewe, Schiewe, A.; … - Erasmus Research Institute of Management (ERIM), … - 2014

In this paper, we propose a novel algorithmic approach to solve line planning problems. To this end, we model the line planning problem as a game where the passengers are players which aim at minimizing individual objective functions composed of travel time, transfer penalties, and a share of...
