5. Numerical Experiments and Analysis

The purpose of this section is to measure the degree of mitigation of different supply chain management strategies on the pig cycle, especially on the degree of fluctuation in the pig price. This section verifies the effectiveness of the supply chain management strategy from the perspective of enterprises (reducing the pig breeding cost and countercyclical regulation) and from the perspective of government (government macroregulation).

5.1. Reducing the Pig Breeding Cost

The pig breeding cost greatly affects the pig price. Assuming that the cost of pig breeding in China is reduced to 2/3 and 1/2 of the original cost, i.e., 9.81 yuan/kg and 7.36 yuan/kg, the other parameters remain unchanged. The simulation results of pig prices are shown in Figure 7.
