Reproducibility dataset for a new family of mixed-integer programming model for irregular strip packing based on vertical slices

This dataset introduces a detailed reproducibility protocol to allow the exact replication of the experiments on Mixed-Integer Programming (MIP) model for irregular strip packing reported in our primary work. Likewise, this dataset provides all raw output data from our experiments used in our primary work. Our reproducibility protocol is based on our RAMNEST V1R3 Java software library of MIP models for irregular strip packing. Our software library implements our new family of NFP-CM-VS MIP models for irregular strip packing and the family of state-of-the-art NFP-CM models introduced by Cherri et al. (2016) and Rodrigues et al. (2017). We evaluate all MIP models in 35 small problem instances, 24 metal instances including pieces with holes, and 11 large problem instances, as detailed in the experimental setup of our work. All MIP models are implemented in our Java software library and solved using the Java API of Gurobi 9.5 with its default parameters. Thus, the use of our software requires the installation of an academic or commercial license of Gurobi 9.5 for UBUNTU. This dataset includes the Java source code and pre-compiled binaries of our software library developed with Netbeans 8.2 for UBUNTU. We also provide all MIP models in LP file format, which allows reproducing our experiments without our software by loading them into Gurobi, or any other MIP solver as CPLEX.

本数据集提供了一套详细的可复现性规程，可精准复现本团队前期核心研究工作中报道的、面向不规则条带排样的混合整数规划（Mixed-Integer Programming, MIP）模型相关实验。同时，本数据集还包含前期核心研究工作中所有实验的原始输出数据。

本可复现性规程基于我们研发的适用于不规则条带排样的混合整数规划模型的RAMNEST V1R3 Java软件库。该软件库实现了我们提出的NFP-CM-VS系列新型不规则条带排样混合整数规划模型，以及Cherri等人（2016）与Rodrigues等人（2017）提出的当前顶尖NFP-CM系列模型。

如本研究的实验设置部分所述，我们共在35个小规模问题实例、24个包含带孔洞工件的金属工件实例以及11个大规模问题实例中，对所有混合整数规划模型进行了评估测试。

所有混合整数规划模型均通过本Java软件库实现，并采用默认参数配置的Gurobi 9.5 Java应用程序编程接口进行求解。因此，使用本软件需在Ubuntu操作系统中安装Gurobi 9.5的学术或商业授权许可。

本数据集包含针对Ubuntu系统、基于NetBeans 8.2开发的本软件库的Java源代码与预编译二进制文件。此外，本数据集还提供了全部采用LP文件格式存储的混合整数规划模型，可直接加载至Gurobi或CPLEX等其他混合整数规划求解器中，无需依赖本软件即可完成实验复现。
