Co-allocation Model for Complex Equipment Project Risk Based on Gray Information

As the fact that complex equipment project is a multi-level co-development network system and milestones connect with each other in accordance with the logical relationship between different levels, we can decompose the complex equipment project into several multi-level milestones. This paper has designed several connecting nodes of collaborative milestone and established a new co-allocation model for complex equipment project risk based on gray information. Take comprehensive trial phase of a large aircraft developed project as an example to prove the effectiveness and feasibility of the above models and algorithms, which provides a new analysis methods and research ideas.
