1, select the appropriate simulation means. In the doctoral thesis, different simulation methods are used to study an experiment. According to the research object and purpose, we can choose the appropriate simulation method to study. Different simulation methods have different advantages and disadvantages and application scope, which need comprehensive evaluation.

2. Establish the model and verify it. Using different simulation methods to study an experiment in doctoral thesis can establish a suitable model and verify it to ensure its accuracy and reliability. In the process of simulation, we need to pay attention to the selection and setting of parameters, as well as the modification and improvement of the model.
