doi:10.3969/j.issn.1004-132X.2023.14.004

Abstract

Abstract: Aiming at the supply chain inventory systems under demand disturbances, a supply chain inventory system optimization model was designed combining improved sliding mode controller and disturbance observer. A dynamic inventory model of a three-echelon networked supply chain system was established based on the product operation logic of the supply chain system. An optimization model combining improved sliding mode controller was designed based on adaptive exponential reaching law and disturbance observer. The model could suppress the influences of demand disturbances on the supply chain inventory system under the premise of ensuring system stability. Simulation comparison experiments verified the effectiveness of the optimization model.

Key words: demand disturbance, supply chain, inventory system, improved sliding mode controller, disturbance observer

摘要： 针对需求扰动作用下的供应链库存系统，设计了一种改进型滑模控制器与扰动观测器相结合的供应链库存系统优化模型。基于供应链系统产品运营逻辑关系建立了三级网状供应链系统的动态库存模型；设计了基于自适应指数趋近律的改进型滑模控制器和扰动观测器相结合的优化模型。在保证系统稳定的前提下，该优化模型能抑制需求扰动对供应链库存系统的影响。仿真对比实验验证了优化模型的有效性。
