Perceiving economic inequality in everyday life decreases tolerance to inequality
(2020)
Economic inequality is one of the main issues of modern societies, and one of the ways to reduce it is through decreasing inequality tolerance and increasing support for economic redistribution. However, there are no ...
Benders, metric and cutset inequalities for multicommodity capacitated network design
(SPRINGER, 2009)
Solving multicommodity capacitated network design problems is a hard task that requires the use of several strategies like relaxing some constraints and strengthening the model with valid inequalities. In this paper, we ...
I know people who can and who cannot: A measure of the perception of economic inequality in everyday life
(2019)
This paper describes the development of the Perceived Economic Inequality in Everyday Life (PEIEL) scale. It is written and validated in Spanish. We first carried out an exploratory study, using a sample of 205 participants ...
Valid Inequalities For A Single Constrained 0-1 Mip Set Intersected With A Conflict Graph
(Elsevier Science BVAmsterdam, 2016)
A priori reformulations for joint rolling-horizon scheduling of materials processing and lot-sizing problem
(2013-06-10)
In many production processes, a key material is prepared and then transformed into different final products. The lot sizing decisions concern not only the production of final products, but also that of material preparation ...
Derivation and generation of path-based valid inequalities for transmission expansion planning
(2022-01-01)
This paper seeks to solve the long-term transmission expansion planning problem in power systems more effectively by reducing the solution search space and the computational effort. The proposed methodology finds and adds ...
Valid inequalities for the synchronization bus timetabling problem
(ELSEVIER, 2016)
Bus transit network planning is a complex process that is divided into several phases such as: line planning, timetable generation, vehicle scheduling, and crew scheduling. In this work, we address the timetable generation ...
Valid inequalities for Lagrangian relaxation in an inventory location problem with stochastic capacity
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
We developed an efficient heuristic to solve a joint location-distribution-inventory model for a three layered supply chain. A firm must locate distribution centers to supply a commodity to spatially distributed retailers ...
Norm inequalities in operator ideals
(Elsevier, 2008-12)
In this paper we introduce a new technique for proving norm inequalities in operator ideals with a unitarily invariant norm. Among the well-known inequalities which can be proved with this technique are the Löwner–Heinz ...
Young's (in)equality for compact operators
(Polish Acad Sciences Inst Mathematics, 2016-05)
If a, b are n × n matrices, T. Ando proved that Young’s inequality is valid for their singular values: if p > 1 and 1/p + 1/q = 1, then λk(|ab∗ |) ≤ λk 1 p |a| p + 1 q |b| q for all k. Later, this result was extended ...
