Machine-based Production Scheduling for Rotomoulded Plastics Manufacturing - Datasets

These datatasets relate to the computational study presented in the paper Machine-based Production Scheduling for Rotomoulded Plastics Manufacturing, authored by Mark Baxendale, James McGree, Aaron Bellette and Paul Corry. They consist of all the randomly generated problem instances.

Problem Instance Data Format:

The included zip file contains a folder for each problem instance (numbered 0 - 49) associated with each F parameter setting (F0, F0_5, F1) and each number of jobs (30, 40, 50). Each problem instance is described by 5 csv files: jobs.csv, machines.csv, scalars.csv, compat.csv, and machcompat.csv.

jobs.csv - Each row represents a different job. The first four values in each row represent the processing times for the load, cook, cool and unload stages respectively. The fifth column gives the surface area of the job. The sixth column defines the due date.

machines.csv - Each row represents a different machine. The first value represents the number of arms on the machine. The second value represents the surface area on each arm.

scalars.csv - The first value represents the number of jobs. The second value represents the number of machines. The third value represents the number of production stages (4). The fourth value represents the M parameter. The fifth value is the operational time per day (mu). The sixth parameter is the non-operational time per day (nu).

compat.csv - This file provides all sigma values, used to indicate the compatibility of batching two jobs together. The value in the ith row and jth column gives the compatibility of batching jobs i and j together.

machcompat.csv - This file provides all kappa values, used to indicate the compatibility of assigning a job to a machine. The rows correspond to machines, the columns to jobs, where the value in the ith row and jth column gives the compatibility of assigning job j to machine i.

本数据集与马克·巴克斯兰德尔（Mark Baxendale）、詹姆斯·麦格雷（James McGree）、阿伦·贝尔莱特（Aaron Bellette）和保罗·科里（Paul Corry）共同撰写的论文《基于机器的旋转模塑塑料制品制造的生产调度》中的计算研究相关。数据集包含所有随机生成的实例问题。

实例问题数据格式：

所包含的zip文件包含每个问题实例（编号0-49）的文件夹，这些文件夹与每个F参数设置（F0、F0_5、F1）以及每个工作数量（30、40、50）相关联。每个问题实例由5个csv文件描述：jobs.csv、machines.csv、scalars.csv、compat.csv和machcompat.csv。

jobs.csv - 每行代表一个不同的工作。每行的前四个值分别代表装载、烹饪、冷却和卸载阶段的加工时间。第五列给出工作的表面积。第六列定义了截止日期。

machines.csv - 每行代表一个不同的机器。第一个值代表机器上的臂的数量。第二个值代表每臂的表面积。

scalars.csv - 第一个值代表工作的数量。第二个值代表机器的数量。第三个值代表生产阶段数量（4）。第四个值代表M参数。第五个值是每天的操作时间（μ）。第六个参数是非操作时间（ν）。

compat.csv - 此文件提供了所有σ值，用于指示将两个工作批量的兼容性。第i行第j列的值给出批量工作i和工作j的兼容性。

machcompat.csv - 此文件提供了所有κ值，用于指示将工作分配给机器的兼容性。行对应机器，列对应工作，其中第i行第j列的值给出将工作j分配给机器i的兼容性。
