【摘要】：国内成品油销售市场开放以来，国内外石油企业纷纷踏入这一领域，这就造成国内成品油市场竞争异常激烈。如何提高市场反应速率，体现竞争优势，如何在供应链库存管理中降低库存成本、提高服务水平、减小牛鞭效应，这些问题已成为国内外所有石油企业所要着重考虑的因素。本文运用系统动力学方法和原理，以河北LF地区的成品油销售企业为研究背景，建立了油库与它所管辖的加油站的两级库存控制的系统动力学模型。首先对供应链库存管理及系统动力学的相关国内外的研究现状进行了综述，对供应链的库存管理基础理论和系统动力学的基础理论进行了简单的介绍。之后以河北省LF成品油销售公司为背景，通过对油库和它所管辖的加油站的两级供应链库存的分析，，确定了这个模型的边界，然后确定了加油站和油库的系统循环图，通过系统循环图建立起油库与加油站的两级库存控制的流量存量图，并对所建的系统动力学模型进行了相关检测。最后运用计算机软件Vensim进行不同客户需求的仿真，以期对未来进行合理的预测。然后针对不同的客户需求条件的模型进行分析和优化，提出了参数和结构优化策略，通过模拟，优化后的策略在库存稳定性和降低总成本上都有明显的优势。
[Abstract]:Since the opening of domestic oil products market, domestic and foreign oil enterprises have stepped into this field, which results in fierce competition in domestic oil products market. How to improve market reaction rate, reflect competitive advantage, reduce inventory cost, improve service level and reduce bullwhip effect in supply chain inventory management have become important factors for all oil enterprises at home and abroad. In this paper, the system dynamics model of two-stage inventory control of oil depot and gas station is established based on the research background of oil product sales enterprises in LF area of Hebei province by using the method and principle of system dynamics. Firstly, the research status of supply chain inventory management and system dynamics at home and abroad is summarized, and the basic theories of supply chain inventory management and system dynamics are briefly introduced. Then, based on the background of Hebei LF Oil Product sales Company, the boundary of this model is determined through the analysis of the inventory of the oil depot and the two-level supply chain of the gas station under its jurisdiction, and then the system cycle diagram of the gas station and the oil depot is determined. The flow inventory chart of two-level inventory control of oil depot and gas station is established by the system cycle diagram, and the system dynamics model is tested. At last, the computer software Vensim is used to simulate the different customer demands in order to predict the future reasonably. Based on the analysis and optimization of different customer demand models, the optimization strategy of parameters and structure is put forward. Through simulation, the optimized strategy has obvious advantages in inventory stability and total cost reduction.
