摘　　要：针对目前服务制造型订单企业的生产调度优化问题,考虑企业资源和加工生产线的限制,以最小化最大订单完工时间为目标函数,建立流水车间订单调度模型,并模拟麻雀觅食过程提出了一种两段式麻雀搜索(two-vector sparrow search algorithm,T-SSA)算法。根据订单调度问题的特点,该文采用生产环节生产线两段式编码方式对个体进行编码;使用权重轮盘赌随机选择机制(考虑订单收益高低、交期紧急程度、订单权重)初始化麻雀种群,保证种群的多样性和质量;并设计麻雀搜索算法中的智能行为,包括发现者移动机制、跟随者跟随机制、警戒者侦察预警机制,防止算法陷入局部最优。最后,仿真类似算法进行类比分析,实验验证了T-SSA的有效性,且求解效率也显著提升;并将T-SSA对应用到上海某西装定制企业订单调度实例中,结果验证了T-SSA算法求解订单调度问题的可行性。Aiming at the current production scheduling optimization problem of service manufacturing order companies,considering the constraints of enterprise resources and processing production lines,and minimizing the maximum order completion time as the objective function,a flow shop order scheduling model is established and a sparrow foraging process,two-vector sparrow search algorithm(T-SSA),is proposed.According to the characteristics of the order scheduling problem,we use a two-stage coding method in the production process to code individuals,with a weighted roulette random selection mechanism(considering the level of order revenue,delivery urgency,and order weight)to initialize the sparrow population to ensure population diversity and quality.Then we design the intelligent behavior in the sparrow search algorithm,including the movement mechanism of the finder,the follower mechanism and the alerter detection and early warning mechanism to prevent the algorithm from falling into the local optimum.Finally,analogous analysis is carried out by simulating similar algorithms,and the experiment verifies the effectiveness of T-SSA,and the solution efficiency is also significantly improved.The T-SSA pair is applied to the order scheduling example of a suit customization enterprise in Shanghai,and the result verifies the feasibility of solving the order scheduling problem by T-SSA.
