【摘要】：绿色再制造作为循环经济的重要组成部分,具有良好的节能、节材和环保效益,具有重要的理论价值和研究意义。本文结合我国再制造产业发展的实际,针对传统再制造模式下旧件小批量个性化生产的现状,提出了面向服务的再制造模式,并对其核心技术问题—再制造毛坯的回收决策与生产调度进行了研究。首先,对比分析了面向服务的再制造模式与传统再制造模式的区别,结合面向服务的再制造模式的概念模型和优势特征阐述了这一模式的内涵;并指出了这一模式的实施路径。其次,通过考虑产品在服役阶段的维修和再制造决策问题,以产品原始生命周期内单位时间的服役成本最小为优化目标,考虑再制造成本服从指数分布的特性,利用威布尔分布来表征失效率函数,通过MATLAB优化工具箱来逼近目标函数的最优解,并以徐工XE80A型挖掘机再制造时机的确定为例,证明了所建决策模型的可行性。然后,设计了面向服务的制造/再制造集成供应链物流网络:考虑了旧件的回收量和再制造率的不确定性特征,建立了混合整数非线性规划模型,对回收站点进行了优化部署,并合理分配了集成中心的物流量,使得原始设备制造商逆向物流网络的运营成本最小。最后,基于再制造生产实践,对再制造修复加工时间进行了模糊处理,并考虑了不同工序之间的存储策略,建立了可批量生产的流水车间调度模型,设计了求解该调度模型的遗传算法,实例验证了模型和算法的有效性和可行性。
[Abstract]:As an important part of circular economy, green remanufacturing has good energy saving, material saving and environmental protection benefits, and has important theoretical value and research significance. Based on the development of China's remanufacturing industry and the current situation of small batch individualized production of old parts under the traditional remanufacturing mode, a service-oriented remanufacturing model is proposed in this paper. The core technical problem of remanufacturing blank recovery decision and production scheduling is also studied in this paper. Firstly, the difference between the service-oriented remanufacturing model and the traditional remanufacturing mode is analyzed, and the connotation of the service-oriented remanufacturing model is expounded with the conceptual model and the advantages of the service-oriented remanufacturing model, and the implementation path of the model is pointed out. Secondly, considering the maintenance and remanufacturing decision of the product in the service stage, taking the minimum service cost per unit time in the original life cycle of the product as the optimization goal, considering the characteristics of the exponential distribution of the remanufacturing cost service. The failure rate function is represented by Weibull distribution, and the optimal solution of the objective function is approached by MATLAB optimization toolbox. The feasibility of the decision model is proved by taking the determination of the remanufacturing opportunity of Xugong XE80A excavator as an example. Then, a service-oriented integrated manufacturing / remanufacturing supply chain logistics network is designed. Considering the uncertain characteristics of the recovery and remanufacturing rate of old parts, a mixed integer nonlinear programming model is established, and the optimal deployment of the recovery station is carried out. The logistics flow of the integration center is allocated reasonably to minimize the operating cost of the original equipment manufacturer reverse logistics network. Finally, based on the practice of remanufacturing, the remanufacturing repair processing time is fuzzy treated, and the storage strategy between different processes is considered, and the flow shop scheduling model of batch production is established. A genetic algorithm for solving the scheduling model is designed, and the effectiveness and feasibility of the model and algorithm are verified by an example.
