Abstract

In our present paper, we formulate and study a prey-predator system with imprecise values for the parameters. We also consider harvesting for both the prey and predator species. Then we describe the complex dynamics of the proposed model system including positivity and uniform boundedness of the system, and existence and stability criteria of various equilibrium points. Also the existence of bionomic equilibrium and optimal harvesting policy are thoroughly investigated. Some numerical simulations have been presented in support of theoretical works. Further the requirement of considering imprecise values for the set of model parameters is also highlighted.
具有收获和最优控制的不精确捕食-捕食模型的理论分析
在本文中,我们建立并研究了一个参数值不精确的食饵-捕食系统。我们还考虑了对猎物和捕食者的收获。然后描述了模型系统的复杂动力学特性,包括系统的正有界性和一致有界性,以及各平衡点的存在性和稳定性准则。并对生物平衡和最优采收策略的存在性进行了深入的研究。本文给出了一些数值模拟来支持理论工作。此外,还强调了考虑模型参数集的不精确值的要求。
