Dynamic Inventory Control Policy for Auto Spare Parts with TwoDimensional Warranty

School of Management,Tianjin University,Tianjin 30072,China

摘要

摘要: 以汽车产品为例,针对失效率以时间或里程为计量单位的单位价值高、需求率低的不可修零部件,以未来销售预测为起点,依据二维保证政策的特点确定某时点处于保证时效内的汽车数量,基于产品可靠性对保证备件的需求进行预测,针对保证备件需求的特点,提出动态分段(Q,r)库存控制策略,通过案例验证了该库存策略可有效降低库存成本支出。

Abstract: Auto manufacturers provide customers with a basic twodimensional warranty that quantifies vehicle lifetime with two metrics: time and mileage. Under such a warranty policy, it is very important to control the spare part inventory. With sales prediction as its starting point, the number of automobiles under guarantee in some period is determined according to twodimensional warranty policies. It is known that the failure rate of some nonrepairable items is determined by age or usage. Based on this property, a model is proposed to forecast the demands of spare parts. Then, with the demands obtained, a multistage (Q, r) dynamic inventory control policy is presented. Case studies are given to show the effectiveness for inventory cost reduction by using the proposed method.
