摘要:

装备保修是装备售后服务的主要内容,合理的保修策略不仅能够降低承制方保修成本,而且能够提高装备可用度。针对在装备售后服务中控制保修成本和保证可用度的问题,在不完全预防性维修下,采用加速失效时间(AFT)模型描述装备故障率,构建了装备二维保修成本和可用度模型并给出了有效解法。在此基础上,权衡军地双方利益,以保修期内费效比最小为优化目标,得到最优预防性维修间隔期。对不同保修期限下最优费效比值进行回归分析,在控制保修成本、保证装备可用度的前提下,得到柔性保修策略方案。最后,通过算例验证了模型的有效性。

Abstract:

Warranty is the primary coverage of equipment after-sale service, and reasonable warranty servicing strategy has significant impact on manufacturer's warranty cost and the product availability. A two-dimensional warranty cost and availability model is developed under preventive maintenance and the solving process proposed, where the function of failure rate is given by accelerated failure time (AFT) model. By modeling the warranty cost and product availability, the optimum warranty servicing strategy is derived to minimize the cost-effect ratio. Then, regression analysis with optimal cost-effect under different warranty regions is used to derive the flexibility warranty servicing strategy. Finally, a numerical illustration is given to examine the validity of the model.

Key words: two-dimensional warranty, preventive maintenance, cost-effective ratio, accelerated failure time (AFT)
