The invention discloses a project performance evaluation and risk early warning method for multi-source heterogeneous scientific
research data, and relates to the technical field of scientific research
project management, and the method comprises the steps: collecting the multi-source heterogeneous scientific
research data, cleaning, converting, filling missing values, and storing in a unified format; extracting performance and risk features, and fusing to obtain a fused
feature set; combining an
analytic hierarchy process, an
entropy weight method and the like to construct a dynamic weight performance evaluation model; constructing a multi-
modal risk
early warning model by adopting multiple algorithms and optimizing a threshold value; collecting data in real time to update a
feature set, and dynamically adjusting the model; and visually outputting a result, generating an improvement suggestion, and forming closed-loop feedback. According to the method, the multi-
source data processing efficiency and evaluation accuracy are improved, the risk early warning timeliness and adaptability are enhanced, a management
closed loop is formed, and the problems of difficult
data integration, evaluation lagging, insufficient early warning and the like of a traditional method are solved.
