A flow-based formulation for parallel machine scheduling using decision diagrams
Daniel Kowalczyk, Roel Leus, Christopher Hojny +1
We present a new flow-based formulation for identical parallel machine scheduling with a regular objective function and without idle time. The formulation is constructed with the h…
The Mobile Production Vehicle Routing Problem: Using 3D Printing in Last Mile Distribution
Yu Wang, Stefan Ropke, Min Wen +1
We study a new variant of the vehicle routing problem, called the Mobile Production Vehicle Routing Problem (MoP-VRP). In this problem, vehicles are equipped with 3D printers, and…
Consistency Cuts for Dantzig-Wolfe Reformulations
Jens Vinther Clausen, Richard Lusby, Stefan Ropke
This paper introduces a family of valid inequalities, that we term consistency cuts, to be applied to a Dantzig-Wolfe reformulation (or decomposition) with linking variables. We pr…
The multi-port berth allocation problem with speed optimization: Exact methods and a cooperative game analysis
Bernardo Martin-Iradi, Dario Pacino, Stefan Ropke
We consider a variant of the berth allocation problem-i.e., the multi-port berth allocation problem-aimed at assigning berthing times and positions to vessels in container terminal…
A column-generation-based matheuristic for periodic train timetabling with integrated passenger routing
Bernardo Martin-Iradi, Stefan Ropke
In this study, the periodic train timetabling problem is formulated using a time-space graph formulation. Three solution methods are proposed and compared where solutions are built…
