摘　　要：针对电力物资供应链库存管理存在的信息中心化严重和各级之间信息传递慢等问题,本文基于区块链的去中心化、信息可追溯、信息不可篡改性和智能合同特征,提出建立以区块链技术为核心的区块化数据库。为验证其在供应链库存管理中的有效性,运用系统动力学对电力物资供应链进行因果回路分析,探讨区块化数据库对原有供应链库存管理产生的影响。建立了由制造商、供应商和物资平台组成的三级供应链系统动力学模型,并将其影响下的改变量加入其中,提出了供应链各节点企业不同合作程度下的库存管理模式。运用Vensim软件进行仿真模拟,对各节点库存量进行对比分析,验证区块化数据库对库存管理的适用性。研究发现,优化后的供应链能够有效减少供应链库存整体牛鞭效应,提高供应链整体响应速度和减少供应链整体库存成本。In view of the problems by serious information centralization and slow information transmission among different levels in the inventory management of power supplies supply chain,this paper proposes to establish a block database with the block chain technology as the core,based on the characteristics of block chain with decentralization,information traceability,information imtamperability and intelligent contract.In order to verify its effectiveness in supply chain inventory management,the cause-and-effect loop analysis of power supply chain is carried out by using system dynamics,with the influence of block database on the original supply chain inventory management discussed.Furthermore,a three-level supply chain system dynamics model composed of manufacturer,supplier and material platform is established,the change quantity under its influence is added into the model,and the inventory management model under different cooperation degree of each node enterprise of the supply chain is proposed.Vensim software was used for simulation,and the inventory of each node was compared and analyzed to verify the applicability of block database for inventory management.It is found that the optimized supply chain can effectively reduce the overall inventory bullwhip effect,improve the overall response speed of the supply chain and reduce the overall inventory cost of the supply chain.
