广电网络运营商属于资金密集型企业,其采购种类繁多,采购成本往往可以达到企业运营成本的60%以上。如何在保证工程建设项目进度的前提下控制库存。已成为摆在项目管理和材料供应商面前的严峻挑战。本文通过分析VIM模式在广电企业中应用的可行性,说明了VMI模式是一种低库存下及时响应客户终端需求的物料供应模式,可以有效地控制建设项目现场和材料供应商的库存,从而降低整个供应链的整体库存费用。并对广电工程项目实施VMI模式涉及的效益风险等因素进行了分析。 相似文献

一种基于作业成本法的多阶段供应商选择方法 总被引:4,自引:0,他引:4
供应商的选择是供应链管理中开发供应商伙伴关系的一项重要内容。现有的供应商选择模型只考虑直接供应商,并没有考虑供应商的供应商因素。本文在现有文献的基础上对供应商的选择模型进行了改进,建立了多阶段供应商选择的混合整数规划模型:既可以选择单阶段供应商,也可选择多阶段供应商,从而使整条供应链达到最优化。在模型中考虑每个潜在供应商的生产能力约束。用成本分析法计算由供应商引起的总成本,增加了供应商选择过程的客观性。 相似文献

This paper investigates a distributed and adaptive approach to manage spectrum usage in dynamic spectrum access networks.
While previous works focus on centralized provisioning, we propose a distributed low complexity approach where nodes self-organize
into coordination groups and adapt their spectrum assignment to approximate the global optimal assignment. We design a distributed
coordination protocol to regulate the coordination format and achieve fast system convergence. The proposed approach achieves
similar performance in spectrum assignment compared to that of the conventional centralized approaches, but significantly
reduces the number of computations and message exchanges required to adapt to topology changes. As a case study, we investigate
the detailed coordination strategy to improve proportional fairness in spectrum assignment, and derive a theoretical lower
bound on the minimum spectrum/througput each node can get from coordination. Such bound can be utilized to guide the coordination
procedures. We also show that the difference between the proposed approach and the global optimal approach is upper-bounded.
Experimental results demonstrate that the proposed approach provides similar performance as the topology-based optimization
but with more than 50% of reduction in complexity.

This paper proposes a prototype system for modeling and simulation of supply chains using a widely accepted agent platform Java agent development platform (JADE). A simple but practical coordination mechanism agent-based dynamic information network for supply chains (ADINS) is employed for the illustration of the suggested system and a simulation experiment is performed using a supply chain model of a Korean LCD manufacturing company. The result shows that the suggested mechanism is successful in reducing bullwhip effects and increasing service rates. 相似文献
