Two Parallel Machine Energy Efficient Scheduling

There are 360 instances for the problem. Each file contains data for an instance. The name of the files represents the parameter setting used. Nx indicates there are x parts in the instance. D1 indicates the short-distance scenario in the instance. D2 indicates the long-distance scenario in the instance. D3 indicates the mixed-distance scenario in the instance. T1 indicates the case where the machines are identical and processing times are generated between 80 and 100 in the instance. T2 indicates the case where the machines are identical and processing times are generated between 40 and 140 in the instance. T3 indicates the case where machine 1 is faster than machine 2. The processing times are generated between 80 and 100 for machine 1, 100 and 120 for machine 2 in the instance. T4 indicates the case where machine 1 is faster than machine 2. The processing times are generated between 20 and 100 for machine 1, 100 and 180 for machine 2 in the instance. C1 indicates full robot move and empty robot move coefficients are equal in the instance. C2 indicates full robot move coefficient is higher than empty robot move coefficient in the instance. We have 5 replications for each parameter setting. r1, 1r2, r3, r4, and r5 indicates the replication number.本数据集共包含360个问题实例，每个文件存储单个实例的相关数据。文件名对应该实例所采用的参数配置方案。 其中，Nx表示该实例内包含x个工件（parts）；D1代表该实例采用短距离作业场景，D2代表长距离作业场景，D3代表混合距离作业场景。 T1表示该实例中所有机器性能完全一致，且加工时间在80至100的区间内随机生成；T2表示该实例中所有机器性能完全一致，且加工时间在40至140的区间内随机生成；T3表示该实例中机器1的性能优于机器2，二者的加工时间分别在80至100、100至120的区间内随机生成；T4表示该实例中机器1的性能优于机器2，二者的加工时间分别在20至100、100至180的区间内随机生成。 C1表示该实例中机器人满载移动与空载移动的系数完全相等；C2表示该实例中机器人满载移动的系数高于空载移动的系数。 每组参数配置下均设置5组重复实验，r1、r2、r3、r4及r5分别代表各组重复实验的编号。
