Optimality-based bound contraction with multiparametric disaggregation for the global optimization of mixed-integer bilinear problems
Castro, Pedro; Grossmann, Ignacio - In: Journal of Global Optimization 59 (2014) 2, pp. 277-306
We address nonconvex mixed-integer bilinear problems where the main challenge is the computation of a tight upper bound for the objective function to be maximized. This can be obtained by using the recently developed concept of multiparametric disaggregation following the solution of a...

Global optimization of bilinear programs with a multiparametric disaggregation technique
Kolodziej, Scott; Castro, Pedro; Grossmann, Ignacio - In: Journal of Global Optimization 57 (2013) 4, pp. 1039-1063
In this paper, we present the derivation of the multiparametric disaggregation technique (MDT) by Teles et al. (J. Glob. Optim., <CitationRef CitationID="CR30">2011</CitationRef>) for solving nonconvex bilinear programs. Both upper and lower bounding formulations corresponding to mixed-integer linear programs are derived using disjunctive...</citationref>

Mixed integer linear models for the optimization of dynamical transport networks
Geißler, Björn; Kolb, Oliver; Lang, Jens; Leugering, … - In: Mathematical Methods of Operations Research 73 (2011) 3, pp. 339-362
We introduce a mixed integer linear modeling approach for the optimization of dynamic transport networks based on the piecewise linearization of nonlinear constraints and we show how to apply this method by two examples, transient gas and water supply network optimization. We state the mixed...

A branch and price algorithm for the minimum power multicasting problem in wireless sensor networks
Montemanni, R.; Leggieri, V. - In: Mathematical Methods of Operations Research 74 (2011) 3, pp. 327-342
The Minimum Power Multicast Problem arises in wireless sensor networks and consists in assigning a transmission power to each node of a network in such a way that the total power consumption over the network is minimized, while a source node is connected to a set of destination nodes, toward...

Multi criteria dynamic design optimization of a small scale distributed energy system
Rieder, Andreas; Christidis, Andreas; Tsatsaronis, George - In: Energy 74 (2014) C, pp. 230-239
The aim of this paper is to analyze the mutual interdependencies and trade-offs between heat storage and district heating network considering economic and ecological aspects. Therefore, a MILP (mixed integer linear programming) problem of a distributed energy system is formulated with a weighted...

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...
