At the same time, it considers the risk elements exist in the project implementation which influent the project implementation, and the values of indexes about every activities in the project is given by expert scoring method, the values of every indexes about the project are also calculated according to the tree structure chart. The advantages and disadvantages of every schemes of project can be acquired. It is more useful and concise for the planning and decision making of the project risk management.
