基于logistic方程的供应商—采购商合作关系的经济模型研究

Economic Model of Suppliers and Buyers Coorperation Based on Logistic Equation

研究了一个供应商和一个采购商的合作关系.基于logistic种群增长模型,建立了供应商和采购商的合作模型,给出了正平衡点存在的条件,分析了边界平衡点和正平衡点的稳定性.通过具体例子的数值模拟说明了模型的有效性.

The coorperation of a supplier and a buyer was studied. A coorperative model for supplier and buyer was proposed based on the logistic equation. Sufficient conditions were given for the existence of positive equi-librium point, and the stability of boundery equilibrium point and positive equilibrium point was analyzed. The simulations of examples were given to illustrate the validity of the model.
