【摘要】：供应链的竞争已成为企业竞争的重要方面之一,在有关供应链管理研究中,库存管理是其重要的研究方向。一个合适的库存管理模式不仅能有效的降低企业成本,还能提高系统运作效率,增加企业的市场竞争能力。因此库存管理方面的研究受到人们的广泛关注。由于供应链系统的复杂性、不确定性,加之计算机仿真技术的发展越来越成熟,运用计算机过程仿真技术来动态模拟供应链的运行过程、优化供应链系统的结构和考察供应链中种种运作策略,已成为供应链管理研究的重要趋势。据此,本文根据国内外研究现状,考虑供应链中零售商之间的两种主要相互关系,结合供应链多级库存管理的相关理论,采用计算机仿真建模的方法对两个集中式库存管理的多级库存系统进行了仿真优化研究。首先,构造了考虑零售商相互关系的两个供应链库存系统结构,并根据系统中各项参数的联系,分别建立了两个库存系统的数学模型,为进一步的仿真与优化提供数据统计上的支持。然后,分别梳理了两个供应链多级库存系统的运作流程,根据该流程,运用Arena仿真软件建立了两个由制造商、分销中心、零售商和需求市场组成的供应链仿真模型,并根据各系统的数学模型,在仿真模型中分别设置了相应的统计数据指标,为进一步的模型分析和系统优化作数据准备。其中,第一个仿真模型模拟了三个零售商相互独立的供应链多级库存系统的运作过程。在该模型中,通过控制零售商和分销中心的订货点和订货批量,对比分析了供应链在不同控制参数下的仿真结果。第二个仿真模型模拟了三个零售商完全关系、库存完全共享的供应链多级库存系统的运作过程。最后,根据仿真模型和相应的统计指标,运用与Arena配套的OptQuest优化软件分别对两个模型中分销中心和零售商的订货策略进行了仿真优化,得到了分销中心和零售商的最佳订货点和最佳订货批量,使得供应链库存系统在保持-定市场满足率的情况下,总库存成本最小。
[Abstract]:The competition of supply chain has become one of the most important aspects of enterprise competition. In the study of supply chain management, inventory management is an important research direction. A suitable inventory management model can not only effectively reduce the cost of the enterprise, but also improve the efficiency of the operation of the system, and increase the competitiveness of the market. Therefore, the research of inventory management has received extensive attention. Because of the complexity of supply chain system, uncertainty, coupled with the development of computer simulation technology is more and more mature, dynamic simulation of supply chain using computer simulation technology to the process of operation process, optimize the structure and study of supply chain system in various operation strategies, has become an important trend in the research of supply chain management. Therefore, according to the research status at home and abroad, considering the relationship between the two major retailers in the supply chain, combined with the theory of supply chain inventory management, by means of computer simulation and modeling the optimization and Simulation Research on two centralized inventory management system for multi echelon inventory. First, we construct two supply chain inventory system structures considering the retailer relationship, and establish two mathematical models of inventory system based on the connection of each parameter in the system, so as to provide data statistics support for further simulation and optimization. Then, the two stage inventory in supply chain system operation process were combing, according to this process, established two by the manufacturer, distributors, retailers and market demand supply chain consisting of a simulation model using the Arena simulation software, and according to the mathematical model of the system, the corresponding statistics indexes are respectively arranged in the simulation model in the model, for further analysis and optimization system for data preparation. The first simulation model simulates the operation process of three retailers' independent supply chain multi echelon inventory system. In this model, by controlling the order point and order batch of the retailer and distribution center, the simulation results of the supply chain under different control parameters are compared and analyzed. The second simulation model simulates the operation process of a supply chain multilevel inventory system with complete relationship between three retailers and fully shared inventory. Finally, according to the simulation model and the corresponding statistical indicators, respectively on the ordering policy of distribution centers and retailers of the two models are simulated and optimized by matching with the Arena OptQuest optimization software, the distribution center and the retailer's optimal order point and order quantity, which makes the supply chain inventory system in certain market meet rate, the minimum total inventory cost.
