分布式库存系统策略探讨与仿真

如何解决供需不平衡,实现供应链中成本与服务水平的协调控制是研究的一个重要问题,分布式库存系统的实施关键在于决策持有多少库存以及需求到达时库存缺乏如何处理。以具有自主决策权的几个零售商为对象,研究其库存转移状况,以及成本与服务水平,通过建立库存调拨模型,提出了三种调拨策略,包括自私型调拨策略,合作型调拨策略,混合型调拨策略,并根据这三种策略运用Anylogic软件进行仿真,分析比较三种策略的有效性,以得到最优结果。

Abstract：

The key point of the study is how to solve the imbalance of supply and demand, and how to coordinate the cost and service level in the supply chain. To solve the key problems in implementing the multi-location inventory system which lie in deciding how many items to hold at each retailer and how to deal with if there is a demand for an item at a retailer that has none of them in stock. A few independent decision-making retailers are the main research objects. It was targeted to study the transfer of their inventory status, as well as the costs and service levels, and through the establishment of inventory transshipment model, three transshipment strategies, including self-based strategy, cooperation-based strategy, hybrid strategy, were suggested. Then the software of Anylogic was adopted to simulate, analyze and compare the effectiveness of the three strategies in order to obtain optimal results.     

城市应急资源调度系统建模与仿真

突发事件发生时,应急资源的合理调度问题尤为重要。如何解决单一城市应急资源供应不足,如何将更多的资源进行整合,选择哪些救援点进行救援,什么时候进行救援,这些都是需要讨论的问题。通过建立虚拟协调中心,将分布式系统的理论应用到整合城市之间应急资源的协同调度管理中,从应急系统成本费用和因施救不及时造成损失的双重角度考虑,将救援成本最小和出救点数量最少作为应急优化目标,建立了针对多救援点事故灾害下的应急资源调度模型,并对资源的动态调度模型及协同过程进行仿真与研究分析。
