Abstract
In most of the leading research on pork supply chain (PSC) analysis, only a certain part of PSC is studied qualitatively or quantitatively. While they analyze the transmission of price in PSC, connection between price and operation of PSC has not been established. In this paper, system dynamics (SD) and supply chain theory are used to analyze the system behavior of PSC. The model takes into account the natural elimination of slaughtered pigs during feeding and the perishable nature of pork as fresh food. Based on the analysis of the logical relationship and data transfer between the links of PSC, the SD model of Shenyang pork supply chain system is formulated, and the corresponding flow diagram and the equations expressing the relationship between variables are developed. The simulation experiments are designed with step demand as the boundary condition of the system. The fluctuation trend of pork price in Shenyang is analyzed, and the robustness of Shenyang PSC is further discussed.
