報告摘要:In this talk, we consider a tri-trophic stochastic food-chain model with harvesting. We establish a necessary and sufficient condition for existence of optimal harvesting strategy and give the optimal harvesting effort and maximum of sustainable yield. The results show that the optimal harvesting strategy is closely related to the stochastic noises in the model.
