摘要
通过对供应链研究现状的分析,进而对供应链中数学模型进行了深入的探讨。论文采用双层规划模型描述了提出的问题,其中上层规划模型是从生产商的角度出发,使得生产成本最小化;而下层规划模型则是从供应商的角度出发,使得收益最大化。文中对双层规划模型设计了相应的模拟退火算法进行求解。算例结果表明,模型和算法都是有效的,从而为供应链中角色决策提供支持。
The research conditions of supply chain were analyzed,and then the mathematical model was discussed in depth.The paper used the bi-level programming model describing the proposed problem,the top model considered the minimum production cost from the view of producer,however,for making the maximum revenue,the bottom model was built from the sight of supplier.Simulated annealing algorithm was designed for the model.The numerical results showed the model and algorithm were valid,thus offering the support for the role,who made decision in supply chain in time.
