Risk quantitative evaluation and hierarchical management method and system for project execution progress state

The invention discloses a risk quantitative evaluation and hierarchical management method and system for a project execution progress state. The method comprises the following steps: calculating a key task completion probability value according to collected task execution progress information; calculating a key task execution progress risk value according to the key task completion probability value; and according to the key task execution progress risk value, performing level-to-level management decision of risk items. The invention provides a scientific research task key task execution progress information acquisition and execution progress risk calculation method, which is helpful for comprehensively mastering the overall execution state of the project and identifying high-risk tasks and key items thereof by taking the expected target and examination requirements of the scientific research project as guidance. And a support is provided for a project research and development team and scientific research man
