Research of Fuzzy Modification of Dynamic System in Biology

摘要：

For the uncertainties induced by seasonal and environmental influences on the propagation of organisms, the membership function was introduced into the existing dynamic systems in biology as regulation factors, in order to approve the systeM model in biology and make them closer to the actual situations. In the mathcmatic model including one predator, a lion, and two preys, a wildebeest and a zebra, factors concerning seasons and the environment of the wildebeest propagation were depicted by the membership function. Through comparative studies and simulation results, it was shown that improved mathematic models are more in conformity with the actual investigation data, and thus presents a new approach, called fuzzy modification, for the modification studies of dynamic systems in biology.
