Characterization and modelling of guillotine constraints
收藏 引用
EUROPEAN JOURNAL OF OPERATIONAL RESEARCH 2008年 第1期191卷 112-126页
作者: Ben Messaoud, Said Chu, Chengbin Espinouse, Marie-Laure Univ Technol Troyes ICD FRE CNRS 2848 LOSI F-10010 Troyes France ENSIEG Lab Automat Grenoble F-38402 St Martin Dheres France
This paper focuses on guillotine cuts which often arise in real-life cutting stock problems. In order to construct a solution verifying guillotine constraints, the first step is to know how to determine whether a give... 详细信息

A heuristic multi-start decomposition approach for optimal design of serial machining lines
收藏 引用
EUROPEAN JOURNAL OF OPERATIONAL RESEARCH 2008年 第3期189卷 902-913页
作者: Guschinskaya, O. Dolgui, A. Guschinsky, N. Levin, G. Ecole Natl Super Mines F-42023 St Etienne 2 France United Inst Informat Problems Minsk 220012 BELARUS
We study an optimal design problem for serial machining lines. Such lines consist of a sequence of stations. At every station, the operations to manufacture a product are grouped into blocks. The operations within eac... 详细信息

An exact approach for the maximum concurrent k-splittable flow problem
收藏 引用
OPTIMIZATION LETTERS 2008年 第2期2卷 251-265页
作者: Caramia, Massimiliano Sgalambro, Antonino Univ Roma Tor Vergata Dipartimento Ingn Impresa I-00133 Rome Italy Univ Naples Federico II Dipartimento Ingn Econ Gest I-80125 Naples Italy
We consider the maximization of a multicommodity flow throughput in presence of constraints on the maximum number of paths to be used. Such an optimization problem is strongly NP-hard, and is known in the literature a... 详细信息
