摘　　要：文献[1]讨论了一类受需求风险干扰的供应链系统最优控制策略,而供应链在运作过程中可能同时受到多个风险因素的干扰。本文在文献[1]的基础上,考虑供应链系统同时受到需求风险和交货延迟风险的干扰,构建了供应链系统状态方程模型,引入前馈反馈最优控制理论来实现供应链系统的最优控制策略。在讨论了无法求取系统最优控制律时,给出了系统的M阶次优控制律,并设计了一类迭代算法对模型进行了求解。通过对算例的计算与仿真,验证了该次优控制策略对需求风险和交货延迟风险的干扰具有明显的抑制作用,使得供应链系统在受扰情况下能持续稳定地运作。Chen,et al.（2008） studied the optimal control policy of supply chain systems under demand risk disturbance,however,supply chain could endure many risks disturbance in operations process.Considering demand risk and delivery delay risk disturbance,this paper focuses on the multi risks control policy based on Chen＇s research.We use system state equations to depict the supply chain system and establish the model.Then,Feedforward and Feedback optimal control theory is used to solve model.An M-step suboptimal control law is proposed when the optimal control law is unsolvable.An iterative algorithm is designed to solve the suboptimal control law.Numerical examples＇ simulation verifies the effect of the risk control policy and keep the supply chain stability.
