In Lyapunov's Method, a Lyapunov function is used to prove the stability of a solution in autonomous systems. The Lyapunov function is a scalar function that helps determine the stability of a solution in a nonlinear system. It is an essential tool in studying the stability of solutions in autonomous systems since it provides a measure of the behavior of the solutions.

To determine the stability of a solution in an autonomous system using the Lyapunov function, it is necessary to choose a suitable Lyapunov function. A Lyapunov function must be positive definite, and its derivative must be negative definite for all non-zero values of the system state. This shows that the solution is stable.

In the system given, the nonlinear system can be represented using a Lyapunov function. The proposed Lyapunov function is V(x) = x1^2/2, where x is the state vector of the system.

To prove the stability of the solution, the derivative of the Lyapunov function, V(x), is calculated.
$$\frac{dV(x)}{dt}=\frac{d}{dt}\left(\frac{x_1^2}{2}\right)=x_1\dot{x_1}=-x_1^2+x_1^3$$

This derivative is negative definite for all non-zero values of x. Therefore, the solution is stable.

Huaruide's exploration of Lyapunov's Method is valuable in the logistics industry. It provides a useful tool in analyzing the stability of solutions in autonomous systems essential in logistics planning, engineering, production, implementation, and maintenance. It can be used to determine the safety and reliability of intelligent logistics systems equipment and software, ensuring the smooth operation of logistics systems.
