Systems Analysis And Modeling Of China’s Crude Oil Supply Chain Network

Crude oil is an important primary energy related to national economy andsecurity. The crude oil processed by China’s oil refinery&petrochemicalenterprises is composed of the self-produced and imported crude oil, amongwhich, the self-produced crude oil is from a wide distribution area such asDaqing oilfield, Tarim oilfield, and marine oilfield etc., meanwhile, the importedcrude oil comes from more than40countries and regions such as Middle East,North Africa, Central Asia etc. The crude oil needed by oil refinery&petrochemical enterprises is transformed to the large coastal transshipment portsor small&medium sized transshipment ports along coast or river through ship,pipeline, railway and other transportation modes, and eventually be transportedto the oil refinery&petrochemical enterprises located in a wide area, such asZhenhai, Dalian, Maoming etc. China’s crude oil supply system is a complexcrude oil supply chain network composing of a variety of crude oil sources,different modes of transport and transit links. Therefore, whether the networkstructure is scientific and reasonable or not will directly affect the operatingperformance of the supply chain network, the stability and security of crude oilsupply, and ultimately the efficiency of oil refinery&petrochemical enterprises.Thus, in order to deeply analyze the structure and operation mode of China’scrude oil supply chain network, this paper carries out the research from thefollowing parts:Firstly, discusses the complex structure of crude oil supply chain network,which is consisted by crude oil sources, interim storage, distribution of oilrefinery&petrochemical enterprises, and crude oil transportation mode andtransportation way. Then, analyzes the components of various supply chainconstituting the supply chain network, and draws the diagram of oil supply chainnetwork structure. Secondly, discusses the various elements of the oil supply chain network,systematically analyzes oil supply chain network by using system dynamicsapproach, and analyzes the logical relationship between the various elementsaccording to the causality diagram and flow chart.Finally, after the above analysis, this paper carries on the analysis of crudeoil supply chain operation mode, including security, stability, operation cost andcoordination. In summary, based on the text, put forward the strategies for theoptimization of crude oil supply chain network structure and mode of operation.According to the structure of crude oil supply chain network in our country,the paper systematically analyzes crude oil supply chain network by using systemdynamics method, constructed supply chain network according to the theory oflinear programming, and studies the composition of various supply chain in thesupply chain network and the logical relationship between the elements of thesupply chain network, which provide basis for refining companies to makedecisions about scientific design in the supply chain network so as to reducecrude oil supply costs and enhance the competitiveness of enterprises.
