【摘要】：为确定最优的制造与再制造策略,对制造新品和再制造品存在质量差异并分别在一二级市场进行销售的混合系统进行研究。从一二级市场收购的旧产品再制造后仅用于满足二级市场的顾客需求,以最小化单位时间总成本为目标,建立了两类决策模型:1 1个制造周期N个再制造周期模型;2 M个制造周期1个再制造周期模型。运用消元法减化模型和利用差分函数对模型求解,得到了相关决策变量的求解公式。分析表明,单位制造新品与再制造品的生产成本和失销成本、单位旧产品的收购成本不会对制造与再制造决策产生影响。随着一、二级市场旧产品买回比率的提高,生产商倾向于采用1个制造周期N个再制造周期安排制造与再制造业务,其生产成本进一步降低。
[Abstract]:In order to determine the optimal manufacturing and remanufacturing strategy, a hybrid system for manufacturing new and remanufactured products with different quality and selling in the primary and secondary markets was studied. Old products purchased from the primary secondary market are remanufactured only to meet customer needs in the secondary market, with the objective of minimizing the total unit time cost, Two kinds of decision models: 1: 1 manufacturing cycle N remanufacturing cycle model and 2 M manufacturing cycle 1 remanufacturing cycle model are established. By using the elimination method to reduce the model and the difference function to solve the model, the solution formula of the relevant decision variables is obtained. The analysis shows that the production cost and the unsold cost of the unit manufactured new and remanufactured products and the purchase cost of the unit old products will not affect the manufacturing and remanufacturing decision. With the increase of purchasing ratio of old products in the secondary market, manufacturers tend to use one manufacturing cycle N remanufacturing cycles to arrange manufacturing and remanufacturing business, and their production costs are further reduced.
