Instance data--Cost-Constrained Fuzzy Weighted Tardiness Scheduling for Unrelated Parallel Machine

In the instance data folder, there are 450 experimental instances given in the dataset. According to the values of θ and β, the instances can be divided into 9 groups, where the values of TF are {0.2,0.4,0.6}, and the values of R are {0.2,0.4,0.6}. Each group is further divided into small-scale and large-scale instances. For the small-scale instances, the number of machines m is set to 4, and the number of jobs n is set to 10, 20, 30, 40, and 50, respectively. For the large-scale instances, the number of machines is set to 8, and the number of jobs is set to 100, 150, 200, 250, and 300, respectively. In each job information file, the first line represents the processing time, the second line represents the release time, the third line represents the due date, the fourth line represents the weight, and the fifth line represents the number of unavailable time periods on the machines. In each job information file, the first 3m rows represent the fuzzy processing times of jobs, with every 3 rows corresponding to the fuzzy processing times of all jobs on one machine. Rows (3m+1) to (3m+3) contain the fuzzy due dates of jobs, and the last two rows represent the job weights and the unit processing costs of machines, respectively.本数据集的实例数据文件夹中共收录450组实验实例。依据θ与β的取值差异，可将所有实例划分为9个组别，其中TF的取值集合为{0.2, 0.4, 0.6}，R的取值集合为{0.2, 0.4, 0.6}。每个组别又进一步细分为小规模实例与大规模实例两类：小规模实例的机器（machine）数量m设为4，工件（job）数量n分别取10、20、30、40、50；大规模实例的机器数量设为8，工件数量分别取100、150、200、250、300。在每份作业信息文件中，首行代表加工时长，第二行代表释放时间，第三行代表交货期，第四行代表权重，第五行代表机器上的不可用时间段总数。该文件的前3m行用于记录工件的模糊加工时长，每3行对应所有工件在单台机器上的模糊加工时长；第(3m+1)行至第(3m+3)行包含工件的模糊交货期；最后两行则分别表示工件权重与机器的单位加工成本。
