Linearized model for optimization of coupled electricity and natural gas systems
Journal of Modern Power Systems and Clean Energy, 2017 In this paper a combined optimization of a coupled electricity and gas system is presented. For the electricity network a unit commitment problem with optimization of energy and reserves under a power pool, considering all system operational and unit ...

Integer convex minimization by mixed integer linear optimization [PDF]
, 2014 Minimizing a convex function over the integral points of a bounded convex set is polynomial in fixed dimension (Grötschel et al., 1988). We provide an alternative, short, and geometrically motivated proof of this result.

A mixed-integer approximation of robust optimization problems with mixed-integer adjustments
Optimization and Engineering, 2023 AbstractIn the present article we propose a mixed-integer approximation of adjustable-robust optimization problems, that have both, continuous and discrete variables on the lowest level. As these trilevel problems are notoriously hard to solve, we restrict ourselves to weakly-connected instances. Our approach allows us to approximate, and in some cases

Automatic instantiation of a Variable Neighborhood Descent from a Mixed Integer Programming model
Operations Research Perspectives, 2017 In this paper we describe the automatic instantiation of a Variable Neighborhood Descent procedure from a Mixed Integer Programming model. We extend a recent approach in which a single neighborhood structure is automatically designed from a Mixed Integer

Mixed-Integer Convex Nonlinear Optimization with Gradient-Boosted Trees Embedded [PDF]
, 2019 Decision trees usefully represent sparse, high dimensional and noisy data. Having learned a function from this data, we may want to thereafter integrate the function into a larger decision-making problem, e.g., for picking the best chemical process ...

, 2020 We introduce the idea that using optimal classification trees (OCTs) and optimal classification trees with-hyperplanes (OCT-Hs), interpretable machine learning algorithms developed by Bertsimas and Dunn [2017, 2018], we are able to obtain insight on the ...

An optimization framework for solving capacitated multi-level lot-sizing problems with backlogging [PDF]
, 2011 This paper proposes two new mixed integer programming models for capacitated multi-level lot-sizing problems with backlogging, whose linear programming relaxations provide good lower bounds on the optimal solution value. We show that both of these strong

Chemical Engineering Transactions, 2014 Integration of scheduling and control can improve the overall performance of a manufacturing process. However, the integration leads to a mixed-integer dynamic optimization problem (MIDO), which could be challenging to solve. We propose a novel algorithm

IDOL: A web application for mixed integer linear multiobjective optimization
SoftwareX, 2022 Practical decision-making very often results in complex multiobjective optimization problems that can be solved only by advanced software. At present, it is available for singleobjective optimization and much less for multiobjective optimization ...
