Optimisation of freight flows and sourcing in sustainable production and transportation networks

Liotta, Giacomo; Stecca, Giuseppe; Kaihara, Toshiya - In: International Journal of Production Economics 164 (2015) C, pp. 351-365

Global supply chains require integrated cost optimisation of sourcing, production and distribution through flexible networks of suppliers, manufacturers and logistics operators. The minimisation of environmental impacts of freight flows must be considered for sustainable development and should...

MILP formulations for the modularity density maximization problem

Costa, Alberto - In: European Journal of Operational Research 245 (2015) 1, pp. 14-21

Cluster analysis refers to finding subsets of vertices of a graph (called clusters) which are more likely to be joined pairwise than vertices in different clusters. In the last years this topic has been studied by many researchers, and several methods have been proposed. One of the most popular...

Optimal integration of solar energy in a district heating network

Carpaneto, E.; Lazzeroni, P.; Repetto, M. - In: Renewable Energy 75 (2015) C, pp. 714-721

The implementation of European Directive 2012/27 calls for the presence of a renewable share inside efficient district heating and cooling. Solar thermal energy can be a viable contribution to this aim but particular attention must be put into its integration inside the district heating systems....

A multi-objective interactive system for adaptive traffic control

Dujardin, Yann; Vanderpooten, Daniel; Boillot, Florence - In: European Journal of Operational Research 244 (2015) 2, pp. 601-610

In this paper, we consider the problem of adaptive traffic control on single junctions with the three following objectives to be minimized: the total waiting time and the number of stops for private vehicles, and a public transport criterion. This problem being modeled as a multi-objective mixed...

The mixed capacitated arc routing problem with non-overlapping routes

Constantino, Miguel; Gouveia, Luís; Mourão, Maria Cândida - In: European Journal of Operational Research 244 (2015) 2, pp. 445-456

Real world applications for vehicle collection or delivery along streets usually lead to arc routing problems, with additional and complicating constraints. In this paper we focus on arc routing with an additional constraint to identify vehicle service routes with a limited number of shared...

Optimisation of the capacity and the dispatch of decentralised micro-CHP systems: A case study for the UK

Merkel, Erik; McKenna, Russell; Fichtner, Wolf - In: Applied Energy 140 (2015) C, pp. 120-134

Cogeneration of heat and electricity constitutes an important pillar in energy and climate policy. The optimal dimensioning and operation of residential micro-combined heat and power (mCHP) systems is an important area of ongoing research, especially because these systems are prohibitively...

Mathematical programming strategies for solving the minimum common string partition problem

Blum, Christian; Lozano, José A.; Davidson, Pinacho - In: European Journal of Operational Research 242 (2015) 3, pp. 769-777

computational biology. In this work we propose the first integer linear programming model for solving this problem. Moreover, on the … basis of the integer linear programming model we develop a deterministic 2-phase heuristic which is applicable to larger … size from the literature by solving the proposed integer linear programming model with CPLEX. Furthermore, new best …

Global optimization method for network design problem with stochastic user equilibrium

Liu, Haoxiang; Wang, David Z.W. - In: Transportation Research Part B: Methodological 72 (2015) C, pp. 20-39

In this paper, we consider the continuous road network design problem with stochastic user equilibrium constraint that aims to optimize the network performance via road capacity expansion. The network flow pattern is subject to stochastic user equilibrium, specifically, the logit route choice...
