【摘要】 仓储式超市是近几年在我国兴起的一种新型零售业态,实行仓储与销售合一、批发和零售兼营的模式。在供应链管理环境下,为了应对激烈的市场竞争,仓储式超市必须采用系统、整体的观点研究整个供应链上物流和信息流的快速流动。由于在采购、销售等各种经营活动中都存在库存,库存水平直接关系到仓储式超市的资金周转和销售利润。因此,研究供应链管理环境下的库存系统对于仓储式超市经营管理具有十分重要的意义。系统动力学(SD)的基本原理和建模方法是本文进行库存系统研究的基础。研究对象是供应商管理库存(VMI)模式与联合库存管理(JMI)模式下的仓储式超市库存系统。本文首先分析了VMI模式和JMI模式下仓储式超市库存系统的业务管理流程,然后系统概要地介绍系统动力学方法的理论和建模步骤。在此基础上,以系统的观点,对VMI模式与JMI模式下的仓储式超市库存系统进行了系统边界分析和系统因果关系分析;然后运用系统动力学的理论和方法,利用系统动力学建模与模拟分析软件VENSIM建立了VMI模式与JMI模式下的仓储式超市库存系统的SD模型,并根据两个仓储式超市的经营销售数据,利用VENSIM软件分别对VMI模式与JMI模式下的仓储式超市库存系统SD模型作了多方案的仿真模拟,最后基于仿真结果提出VMI模式与JMI模式下仓储式超市库存系统的库存优化建议。本文的现实意义在于把系统动力学中对企业存储环节的一般性研究具体到供应链管理环境下的仓储式超市库存系统的研究中来,通过建立起相应的SD模型并进行多方案的仿真模拟,通过对仿真结果的分析力图为供应链管理环境下的仓储式超市进行库存优化提供一些借鉴。更多还原

【Abstract】 The warehouse supermarkets have emerged as a new retail concept in China over the recent years, which is characterized by a business model integrating warehousing and sales functions while offering both wholesale and retail services. Under a supply chain management context, the warehouse supermarkets have to adopt systematic and holistic approach in analyzing the rapid logistics and information flows along the entire supply chain in order to deal with fierce competition. As inventories exist throughout business activities including procurement and sales, the cash flow and sales revenue of the supermarket operators are hinged upon inventory levels. Therefore, the study of inventory system in the context of supply chain management holds great significance for their operations and management.The basic principles and modeling methodologies of System Dynamics (SD) are applied in the study of inventory systems in the paper. The object of the study is the supermarket warehouse inventory systems under Vendor Managed Inventory (VMI) and Jointly Managed Inventory (JMI) models.The paper starts with an analysis of business management processes for inventory systems, followed by a systematic overview of SD theories and modeling processes. On this basis, the paper conducts system boundary analysis and system cause-effect analysis of the inventory systems under VMI and JMI models. Using the concept and methodologies of SD, the modeling and simulation software VENSIM is applied to develop models for supermarket warehouse inventory systems. Based on operations and sales data from 2 supermarkets, SD models for multiple scenarios are developed. The inventory optimization suggestions are offered based on simulation results.The paper applies general SD analysis over real-world corporate storage links to the study of specific inventory systems at warehouse supermarkets by conducting multi-solution simulation analysis based on relevant SD models. The analysis of simulation results is made to offer effective suggestions in inventory optimization at warehouse supermarkets from the perspective of supply chain management.更多还原
