WebJun 1, 2007 · Abstract. We combine mixed-integer linear programming (MILP) and constraint programming (CP) to solve an important class of planning and scheduling problems. Tasks are allocated to facilities using MILP and scheduled using CP, and the two are linked via logic-based Benders decomposition. Tasks assigned to a facility may run in parallel … Web1 day ago · Besides using branch and bound, a few other solution methods involve novel reformulations and decomposition strategies [87], [89], which include Benders decomposition [74] and parametric programming [6], [30]. However, these papers only reported computational experiments on small-sized instances.
[2105.13076] Consistency Cuts for Dantzig-Wolfe Reformulations
WebIn this paper, we study bilevel mixed integer programming (MIP) problem and present a novel computing scheme based on reformulations and decomposition strategy. By converting bilevel MIP into a constrained mathematical program, we present its single-level reformulations that are friendly to perform analysis and build insights. WebJan 1, 2016 · Based on this single-level reformulation, a decomposition algorithm is developed that converges to the global optimal solution in finite iterations.

WebDec 31, 2008 · First we cover reformulations based on decomposition, such as Lagrangean relaxation, the Dantzig-Wolfe reformulation and the resulting column generation and … WebApr 14, 2024 · This paper studies a telecommunications hub location model that includes the classical capacitated facility location problem on a wireline network, as well as a wireless network with technological constraints on crane-rain radius, line-of-sight, and capacity. There are multiple wireline and wireless hub types, differing in costs and … WebMay 27, 2024 · This paper introduces a family of valid inequalities, that we term consistency cuts, to be applied to a Dantzig-Wolfe reformulation (or decomposition) with linking variables. We prove that these cuts ensure an integer solution to the corresponding Dantzig-Wolfe relaxation when certain criteria to the structure of the decomposition are met. We … feeding dress for babies
