The first chapter starts with the definition of risk assessment, the present situation at home and abroad, and the development prospect, explaining why we should study risk assessment.

The second chapter introduces some terms used in risk assessment so that you can let others know when you use them in the third chapter.

The third chapter is the process and method of risk assessment, or some successful cases can be cited if the content is not enough.

Chapter four is a summary.

Because I don't know what kind of risk assessment you are, I can only use the general format of the paper.
