基于风险的供应链智能维护决策模型

摘要

在设备智能维护决策理论的基础上，建立基于风险的供应链风险智能维护决策模型。以供应链长期运作成本率最低为目标，借助半马尔可夫决策相关理论，对供应链风险智能维护决策模型进行构建，给出了模型的相关算法，并以实例验证模型及算法的有效性。%Traditional supply chain risk remedial maintenance decision not only need high maintenance costs but also make supply chain node enterprises a huge loss .T he supply chain risk E-maintenance deci-sion can implement targeted maintenance based on risk prediction .Since there is a certain similarity be-tween supply chain risk and equipment failure and the equipment failure E-maintenance decision had been researched by many researchers .In this paper ,supply chain risk E-maintenance decision model is built by using the Semi-Markovian decision theory to the lowest rate of long-term operating costs of the sup-ply chain target ,then the algorithm of model is given .At last ,the validity of the model and algorithm is verified in the examples .
