摘要:

在旨在提高本德尔斯分解性能的众多加速技术中,统一割平面生成方案近来备受关注。统一割平面旨在在最优性割平面和可行性割平面的生成之间实现更好的平衡,同时还提供一种比较不同可行性割平面强度的方法。我们的目标是在多商品固定费用网络设计问题(MCFNDP)的背景下评估多种统一和不同的本德尔斯割平面的实验性能。我们在共同的数学结构和符号下表达所考虑的每个统一或不同本德尔斯割平面的构造。我们还解释了本德尔斯割平面的通用公式如何专门化为符合MCFNDP的规范。此外,当基准由异构问题实例组成时,我们建议了定制方法来比较几种求解方法的性能。我们报告了一项系统实证分析的结果,该分析比较了50种涉及统一或不同割平面的本德尔斯方法在应用于由标准化MCFNDP实例组成的通用测试平台时的性能。分析确定了少数领先的本德尔斯方法,即具有静态布伦登贝格 - 施图尔斯伯格割平面和侯赛尼 - 特纳l1 - 最深割平面的方法。此外,我们还报告了使用Gurobi和CPLEX作为SMS++计算库的支持求解器所获得的结果。

英文摘要:

Among the many types of acceleration techniques designed to improve the performance of Benders decomposition, unified cut generation schemes have recently attracted a keen interest. Unified cuts aim for a better balance between the generation of optimality and feasibility cuts, while also providing a way to compare the strengths of different feasibility cuts. Our goal is to assess the experimental performance of a broad selection of unified and distinct Benders cuts in the context of the multi-commodity fixed-charge network design problem (MCFNDP). We express under a common mathematical structure and notation the construction of each unified or distinct Benders cut considered. We also explain how the generic formulations of the Benders cuts can be specialized to conform to the specifications of the MCFNDP. In addition, we suggest bespoke methods for comparing the performance of several solution methods when the benchmark is made up of heterogeneous problem instances. We report the results of a systematic empirical analysis comparing the performances of 50 Benders methods involving unified or distinct cuts in applications to a common testing bench made up of standardized MCFNDP instances. The analysis identifies a small number of leading Benders methods, namely those featuring the static Brandenberg-Stursberg cuts and the Hosseini-Turner l1-deepest cuts. In addition, we also report results obtained by using both Gurobi and CPLEX as the supporting solver to the SMS++ computation library.
