针对传统的加工与装配分阶段独立调度中资源利用率不高的问题,将加工与装配联合同时进行调度。在考虑工件批量和批次的前提下提出一种改进遗传算法求解该问题,以最小化最大完工时间为优化目标建立数学模型,根据问题特性提出一种工件末工序前移的邻域结构,提升了算法的局部搜索能力进而改善整体求解质量。设计了一种基于装配设备负载均衡的混合贪婪解码方法,完成了装配设备选择。考虑到实际车间中机器故障的特点,提出了相应的响应策略和染色体更改规则,解决了动态调度问题。最后通过算例分析验证了所提算法和策略求解该问题的可行性和有效性。

To solve the problem of low resource utilization in traditional independent scheduling of machining and assembly by stages, the machining and assembly are simultaneously scheduled. An improved genetic algorithm is designed to solve the problem by considering the batch and sublots of the workpiece. First, a mathematical model is established to minimize the maximum completion time. According to the problem characteristics, a neighborhood structure with the workpiece’s last process is proposed, which enhances the local searching ability of the algorithm and improves the overall solution quality. Furthermore, a hybrid greed decoding method based on the load balancing of assembly equipment is designed to complete its selection. Considering the characteristics of machine breakdown in a real workshop, a corresponding response strategy and chromosome changing rule are introduced to solve the dynamic scheduling problem. Finally, the feasibility and effectiveness of the proposed algorithm and strategy for solving the problem are verified by example analysis.
