参数不确定的鲁棒再制造规划

Robust Remanufacturing Planning with Parameter Uncertainty

Zhicheng Zhu, Yisha Xiang, Ming Zhao, Yue Shi

摘要:

我们考虑的问题,再制造规划的统计估计误差的存在。确定最佳的再制造时机,首先,需要建模的系统的状态转换。然而,对这些概率的估计常常受到数据不足的影响,而且很不准确,导致性能严重下降。为了减轻转移概率的不确定性的影响,我们开发了一种新的数据驱动的再制造规划建模框架,决策者可以保持稳健的统计估计误差。我们将再制造规划问题建模为一个鲁棒的马尔可夫决策过程,并构造包含高置信度真实转移概率分布的模糊集。我们进一步建立结构属性的最优鲁棒政策和见解再制造规划。对NASA涡扇发动机的计算研究表明,我们的数据驱动的决策框架始终产生更好的最坏情况下的性能和更高的可靠性的性能保证

英文摘要:

We consider the problem of remanufacturing planning in the presence of statistical estimation errors. Determining the optimal remanufacturing timing, first and foremost, requires modeling of the state transitions of a system. The estimation of these probabilities, however, often suffers from data inadequacy and is far from accurate, resulting in serious degradation in performance. To mitigate the impacts of the uncertainty in transition probabilities, we develop a novel data-driven modeling framework for remanufacturing planning in which decision makers can remain robust with respect to statistical estimation errors. We model the remanufacturing planning problem as a robust Markov decision process, and construct ambiguity sets that contain the true transition probability distributions with high confidence. We further establish structural properties of optimal robust policies and insights for remanufacturing planning. A computational study on the NASA turbofan engine shows that our data-driven decision framework consistently yields better worst-case performances and higher reliability of the performance guarantee
