【摘要】：石油资源的不可再生特性和重要战略储备物资作用,时时刻刻影响着一个国家的国防、社会和政治稳定,是一个国家的经济命脉,也是当今社会发展的坚强基石。随着国际市场的冲击和政策在市场调控下逐渐减弱的趋势,国内的石油行业既有行业发展的机遇,更有竞争带来的危机。就目前中石油负责油品配送的物流企业而言,油品配送作为石油行业供应链末端,受制于加油站点、运输队、油品仓库和各级办公机关等。由于各级公司和各个区域销售点都严格按照相应的制度约束,各自为政、独立经营,出现了大量运力浪费,车辆迂回,空载率高,油品的物流配送成本居高不下等问题。需要进一步完善物流链,减少物流运作的成本,提高企业发展潜力。本文以优化川庆钻探重庆运输总公司配送方案为核心,进一步分析该公司现有配送模式及过程,采用配送优化的相关理论和经验,提出了改进策略的方向和方案,实现优化油品销售企业的联合配送,以期打破行业内企业现有油品配送费用居高不下的瓶颈。首先针对一、二级两级配送衔接不畅的矛盾突出点,通过分析油品配送系统和配送网络优化情况,进一步提出了优化油品两级联合配送网络的方案；结合网络模型和数学模型,用电子数据表等方法演算出一级配送各物流节点间的单位运价；用WinQSB等软件计算最优线路和联合配送网络中的最小单位运价；进而完善了油品配送中的油品仓库选择及配送优化问题,实现了两级联合配送优化。
[Abstract]:The non-renewable characteristics of petroleum resources and the important role of strategic reserve materials affect the national defense, social and political stability of a country all the time, as well as the economic lifeline of a country, and also the strong foundation stone of social development today. With the impact of the international market and the weakening trend of the policy under the market regulation, the domestic oil industry has not only the opportunity for the development of the industry, but also the crisis brought by competition. As for the logistics enterprises in charge of oil distribution in PetroChina, oil distribution, as the end of supply chain of petroleum industry, is restricted by refueling stations, transportation teams, oil product warehouses and offices at all levels. As companies at all levels and regional sales points are strictly in accordance with the corresponding system constraints, independent management, there are a large number of transport capacity waste, vehicles circuitous, high no-load rate, oil distribution costs remain high, and so on. The logistics chain needs to be further improved to reduce the cost of logistics operation and improve the development potential of enterprises. This paper focuses on optimizing the distribution scheme of Chuan Qing drilling Chongqing Transportation Corporation, further analyzing the existing distribution mode and process of the company, adopting the relevant theory and experience of distribution optimization, and putting forward the direction and scheme of improving strategy. To optimize the joint distribution of oil sales enterprises in order to break the bottleneck of the existing oil distribution costs in the industry. First of all, aiming at the contradiction that the first, second and second levels of distribution are not well connected, by analyzing the situation of oil distribution system and distribution network optimization, this paper further proposes a scheme to optimize the two-level joint distribution network of oil products; combining the network model with the mathematical model, The unit freight rates among the first class distribution nodes are calculated by using the spreadsheet and other methods, and the minimum unit freight rates in the optimal lines and joint distribution networks are calculated by WinQSB and other software. Furthermore, the selection and optimization of oil warehouse in oil distribution are improved, and the two-level joint distribution optimization is realized.
