Optimal Control Policies of Pests for Hybrid Dynamical Systems

Figure 8

The effects of ET and 𝛼₁ of model (11) on the control strategies. The initial values are 𝑥₁=1.3;  𝑥₂=1.5; and  𝑦=5, and parameters are fixed as follows: 𝛿₁=0.65,  𝛿₂=0.7,  𝛿₃=0.95,  𝜎=1,  ET=8,  𝑇=4,  𝑎₁=0.75,  𝑎₂=0.85,  𝛼₂=0.85,  𝑐₁=0.2,  𝐾₁=20,  𝑏=0.25,  𝑐=0.3,  𝐴₂=0.85,  𝐾₂=30,  𝑐₂=0.65,  𝑊₁=0.45,  𝑊₂=0.75,  𝑑=0.25, and  𝑟=1.2.
