Abstract

In recent years, the issue of mobility has taken on a prominent position in the international debate. The movement of people and goods is essential to meet the needs of the community, but the progressive growth of the propensity to move involves a series of negative effects from an economic, social and environmental point of view. For this reason, one of the main tools for improving the environmental and energy efficiency of transport is the electrification of vehicles. The growth of the electric mobility market does not depend exclusively on the development of electric vehicles but involves an investment and a management component that refer to the installation of recharging points at specific stations and related maintenance. This paper is based on BaxEnergy Italia S.r.l., a technological company, which evaluated, through the S-LCA, the social and socio-economic aspects of the software solution designed and developed to monitor the functioning of public charging infrastructures for electric vehicles.

Abstract

International audience; his paper addresses the problem of generating strong convex relaxations of Mixed Integer Quadratically Constrained Programming (MIQCP) problems. MIQCP problems are very difficult because they combine two kinds of non-convexities: integer variables and non-convex quadratic constraints. To produce strong relaxations of MIQCP problems, we use techniques from disjunctive programming and the lift-and-project methodology. In particular, we propose new methods for generating valid inequalities by using the equation Y = x x T . We use the concave constraint xx^T - Y psd to derive disjunctions of two types. The first ones are directly derived from the eigenvectors of the matrix Y − x x^T with positive eigenvalues, the second type of disjunctions are obtained by combining several eigenvectors in order to minimize the width of the disjunction. We also use the convex SDP constraint Y - xx^T psd to derive convex quadratic cuts and combine both approaches in a cutting plane algorithm. We present preliminary computational results to illustrate our findings.
