多级供应链系统成本分析随机网络模型及算法研究

供应链成本管理是企业战略管理的核心组成部分。为研究多级供应链网络系统的成本组成及其分布特征、分析各节点企业的成本管理对多级供应链网络系统的影响、找到供应链系统成本管理中的薄弱环节和关键企业,本文构建了多级供应链系统成本的随机网络分析模型。首先研究了模型的结构性质特征,给出成本分布特征的解析算法。然后扩展模型,分别从系统成本类型构成(生产成本、库存成本和物流成本)和系统对企业成本波动的灵敏度两个角度深入研究多级供应链网络成本问题。数值算例分析结果说明了多级供应链网络系统成本分析模型和相关算法的有效性和实用性。

The Study of Multi-stage Supply Chain Cost Distribution Based on GERT Model

Supply chain cost management is an important part in enterprise strategic management. The components and distribution problem of cost in multi-stage supply chain networks is studied in this paper. Based on the graphical evaluation and review technique, a novel stochastic network mathematical model for cost analysis in multi-stage supply chain networks is built. Model structure characteristics and parsing algorithm are provided firstly. Further, to study the effects of cost components (production cost, inventory cost and transportation cost) and cost fluctuations of supply chain members on total cost, we provide algorithms based on the proposed cost analysis model is provided. Finally the effectiveness and flexibility of proposed model and algorithms are verified by simulation study.
