The problem background
Renewable resources should be moderately developed ------- Achieve maximum output or best benefit on the premise of continuous and stable production
Problems and analysis
- stay The catch is stable Under the premise of , How to control fishing to maximize production or maximize benefits ?
- If the catch is equal to the natural increase , The amount of fish in the fishing ground will remain unchanged , The catch is stable .
Yield model
Equilibrium point and stability of first order differential equation
direct method , Do not solve the judgment x0 The method of stability
Yield model ( First, the output is stable –> Solve the maximum output )
Benefit model ( The catch is stable –> Maximum benefit of solution )
