摘要:

针对船舶小组立装焊过程中物料配送延迟、设备故障等异常状况频发导致的生产进度滞后、生产计划需重新调整问题,提出一种多场景多目标动态变化重调度算法.首先,根据生产阶段和异常扰动的不同选取目标函数,并构建包含场地约束、任务先序约束和人力资源约束的数学模型;其次,引入场地配置算法,采用改进的基于参考点的非支配排序算法求解,增加交叉检查机制,设计基于任务序列的变异算子,融合多染色体机制,与场地配置算法相结合进行求解;之后,提出了面向船舶小组立装焊重调度的染色体序列距离计算方法,描述重调度算法解与初始计划的差异大小,与R2指标结合,定义Pareto-R2双标准选择算子,兼顾算法多样性和收敛性;最后,基于工程案例设计对比实验,验证了提出的重调度算法的有效性.

Abstract:

A multi-scenario and multi-objective dynamic change rescheduling algorithm is proposed to address the production schedule delays and the need for adjustments caused by frequent abnormal conditions, such as material delivery delays and equipment failures in the vertical assembly welding process of shipbuilding teams. First, the objective function is selected based on different production stage and abnormal disturbance, and a mathematical model is then developed, incorporating site constraints, task precedence constraints, and human resource constraints. Next, a site allocation algorithm is introduced, and an improved non-dominated sorting algorithm based on reference points is adopted to solve the problem. A cross-checking mechanism implemented, alongside a task-sequence-based mutation operator, and the multi-chromosome mechanism is integrated with the site allocation algorithm. Afterwards, a method for calculating the chromosome sequence distance in the ship group vertical assembly welding rescheduling is proposed, and the difference between the rescheduling algorithm solution and initial plan is described. An R2 indicator is combined with a Pareto-R2 double standard selection operator, which ensures both diversity and convergence of the algorithm. Finally, comparative experiments are conducted based on engineering cases to validate the effectiveness of the proposed rescheduling algorithm.
