Branch and price for nonlinear production-maintenance scheduling in complex machinery
João Dionísio, Ambros Gleixner, João Pedro Pedroso +1
This paper proposes a mixed-integer nonlinear programming approach for joint scheduling of long-term maintenance decisions and short-term production for groups of complex machines…
Exact Methods for Recursive Circle Packing
Ambros Gleixner, Stephen Maher, Benjamin Müller +1
Packing rings into a minimum number of rectangles is an optimization problem which appears naturally in the logistics operations of the tube industry. It encompasses two major diff…
Cutting Stock with Binary Patterns: Arc-flow Formulation with Graph Compression
Filipe Brandão, João Pedro Pedroso
The cutting stock problem with binary patterns (0-1 CSP) is a variant of CSP that usually appears as a relaxation of 2D and 3D packing problems. We present an exact method, based o…
Unit commitment with valve-point loading effect
João Pedro Pedroso, Mikio Kubo, Ana Viana
Valve-point loading affects the input-output characteristics of generating units, bringing the fuel costs nonlinear and nonsmooth. This has been considered in the solution of load…
Multiple-choice Vector Bin Packing: Arc-flow Formulation with Graph Compression
Filipe Brandão, João Pedro Pedroso
The vector bin packing problem (VBP) is a generalization of bin packing with multiple constraints. In this problem we are required to pack items, represented by p-dimensional vecto…
Bin Packing and Related Problems: General Arc-flow Formulation with Graph Compression
Filipe Brandão, João Pedro Pedroso
We present an exact method, based on an arc-flow formulation with side constraints, for solving bin packing and cutting stock problems --- including multi-constraint variants --- b…
