Software Project Risk Management Model Based on Credal Networks

To handle with the complexity and uncertainty of software project,the paper proposes a software project risk management model based on credal networks. The model can handle experts’ imprecise beliefs as well as their disagreement when quantifying the influences of risk factors. Practice proves that the model can make the best of project data and experts’ experience to predict risks and identify the sources of risk through probability inference,so that the risk managers can take proper measure to reduce the proba-bility of risk occurrence.
