云服务模式下配送需求预测与库存配置联合决策模型

在回顾传统多级库存控制策略的基础上,从管理主体、主要思想、优缺点和实施策略等方面与云服务模式下的库存控制策略进行对比分析,发现云服务模式下的库存控制策略有利于实现库存信息的多方向聚集和库存资源的网络化控制。以总成本最低和预测误差最小为目标构建云服务模式下的配送需求预测与库存配置联合决策模型;通过算例实验发现:联合决策模型与独立决策模型相比,在不同问题规模下的稳定性较好,依然保持着成本优势。

“1+X”证书融入专业教学改革的运行逻辑与实践路径

以物流管理专业为例,探讨了“1+X”证书融入专业教学改革的运行逻辑与实践路径。“1+X”证书制度的有效实施必须从岗、课、赛、证四个维度实现标准、体系、要求、内容、过程和评价六个方面的对接。而重构书证融通的人才培养方案能实现标准对接;搭建课证融合的课程体系能实现体系对接;推行五位一体的教学方法能实现过程对接;优化多元多维的评价方法能实现评价对接;打造育训结合的培训体系能实现要求对接;开发产教融合的教学资源能实现内容对接。

An inventory positioning and location decision model based on centralized storage and lateral transshipment in multi-echelon supply chain

The two-echelon inventory system considered in this work is based on one single supplier, multiple distribution centers, and multiple retailers. In each echelon safety inventory is centralized stored in several centralized storage centers and lateral transshipment of safety stock is permitted between centralized storage site and non-centralized storage sites. The inventory positioning and location decision model developed focuses on safety stock cost, lateral transshipment cost, transportation cost, construction cost and shortage cost in multi-echelon supply chain. Numerical experiments show that: no matter whether in the echelon of distribution centers or retailers the factors which affect the selection from one single centralized storage center or multiple centralized storage centers are distance between distribution centers or retailers, unit transshipment cost and unit inventory carrying cost.
