Research on Internal Supply Chain Model of LG Coal Mine

This paper takes large coal companies as research objects and uses cost control as the basis for the internal supply chain of large coal companies. It is pointed out that the goal of the internal operation of the large coal enterprise supply chain is to achieve a balanced coal supply for coal end customers, achieve double satisfaction of coal supply chain enterprises and customers and ultimately maximize general utility. This paper aims to optimize the supply chain in the development of LG coal mine recycling economy. Use existing research methods to solve practical business problems, read a large number of domestic and foreign literature on internal supply chain optimization, and summarize the characteristics and common structure of the internal supply chain of coal companies. Subsequently, through field research, the structure of the internal supply chain of the coal mine was analyzed, and the production process, the selection process, the uncertainty of the transportation and sales process and the necessity of the optimization of the internal supply chain of the coal mine were qualitatively analyzed. Based on the existing theoretical results, the method of optimizing the internal supply chain is compared, and the method suitable for optimizing the internal supply chain of coal mine is selected. The questionnaire survey method was used to obtain the customer satisfaction evaluation index. Maximizing customer satisfaction and company profitability as the optimization goal, taking production capacity, washing capacity and transportation capacity as the constraints of the coal mine internal supply chain target planning optimization model. Based on the overall coordination of the internal supply chain, coal mine production and sales decisions. Finally, the optimal production and sales decisions of the coal mine were obtained, and the optimization results were evaluated.
