Risk Assessment and Management of National Defense Engineering Construction Based on HHM-RFRM

The risk of the national defense engineering construction is generated under the influence of various factors such as personnel, mechanical equipment and environment. This paper uses Hierarchical Holographic Modeling ideas and Risk Filtering, Rating and Management theory(HHM-RFRM) research method, constructs a risk measurement model for multi-dimensional construction risk scenarios by using repeatedly iterative methods; combined with Bayes’ theorem, filters and grades multi-dimensional construction risk scenarios qualitatively and quantitatively, and finally takes a national defense engineering construction as an example to verify the practicability of the proposed model and the feasibility of the method. The evaluation method overcomes the limitations of the traditional risk assessment method with a single perspective and a single model, and better expresses the authenticity of the risk and the complexity of the system, and provides a theoretical basis for the construction risk management and decision-making of the position and practical reference.
