The main purpose of this research is to help managers and decision-makers effectively make decisions and control risk expansion and occurrence in complicated projects in an era of technical development in order to complete the project. Aiming at project risk management from three aspects, WBS, OBS, and RBS, this paper solves the problem of traditional risk management control. Furthermore, this research conducts a comprehensive evaluation through ANP and determines risk weight and ranking in the quantization method to render risk identification more perfectly. Finally, this paper presents an application of an actual case of the aerospace industry, analyzes and solves the project risk management problems to verify the usability of such a method, and offers follow-up suggestions. This study would help decision-makers make objective and effective management decisions and distribute resources under the multi-project mode.
