MIP approaches for the integrated berth allocation and quay crane assignment and scheduling problem

A Agra, M Oliveira - European Journal of Operational Research, 2018 - Elsevier
In this paper we consider an integrated berth allocation and quay crane assignment and
scheduling problem motivated by a real case where a heterogeneous set of cranes is …

Mixed integer formulations for a short sea fuel oil distribution problem

A Agra, M Christiansen, A Delgado - Transportation science, 2013 - pubsonline.informs.org

Valid inequalities based on simple mixed-integer sets

S Dash, O Günlük - Mathematical Programming, 2006 - Springer
In this paper we use facets of simple mixed-integer sets with three variables to derive a
parametric family of valid inequalities for general mixed-integer sets. We call these …

Discretized formulations for capacitated location problems with modular distribution costs

I Correia, L Gouveia, F Saldanha-da-Gama - European Journal of …, 2010 - Elsevier
In this paper we study a discretization reformulation technique in the context of a facility
location problem with modular link costs. We present a so-called 'traditional'model and a …

Two-step MIR inequalities for mixed integer programs

S Dash, M Goycoolea, O Günlük - INFORMS Journal on …, 2010 - pubsonline.informs.org
Two-step mixed integer rounding (MIR) inequalities are valid inequalities derived from a
facet of a simple mixed integer set with three variables and one constraint. In this paper we …

Lifting two-integer knapsack inequalities

A Agra, MF Constantino - Mathematical Programming, 2007 - Springer
In this paper we discuss the derivation of strong valid inequalities for (mixed) integer
knapsack sets based on lifting of valid inequalities for basic knapsack sets with two integer …

Mixing MIR inequalities with two divisible coefficients

M Constantino, AJ Miller, M Van Vyve - Mathematical Programming, 2010 - Springer
This article is a polyhedral study of a generalization of the mixing set where two different,
divisible coefficients are allowed for the integral variables. Our results generalize earlier …

Overview and Research Opportunities in Energy Management for Port Integrated Energy System

W Huang, M Yu, H Li, N Tai - … Management of Integrated Energy System in …, 2023 - Springer
Under the background of 'carbon peak, carbon neutrality', port energy conservation and
emission reduction are imminent. The structure of a green low-carbon port is complex …

Multicommodity multifacility network design

A Atamtürk, O Günlük - Network Design with Applications to Transportation …, 2021 - Springer
We consider multicommodity network design models, where capacity can be added to the
arcs of the network using multiples of facilities that may have different capacities. This class …

The minimum cost design of transparent optical networks combining grooming, routing, and wavelength assignment

A Agra, A de Sousa… - IEEE/ACM Transactions …, 2016 - ieeexplore.ieee.org
As client demands grow, optical network operators are required to introduce lightpaths of
higher line rates in order to groom more demand into their network capacity. For a given …
