Hierarchical network-based safety assessment decision support system for thermal power plants

We present a new approach to design and develop a safety assessment decision support system (SADSS). This approach can improve extension of knowledge and efficiency of logic inference, combining with hierarchical network and the characteristic of the safety assessment process to build knowledge base. Based on investigation on inference engine and the design method of knowledge base, we introduced in detail how to set up SADSS for thermal power plant based on hierarchical network in this paper. According to introduce decision support system to safety assessment of power production process for power plant, it assists appraisers in making decisions and make the safety assessment process for thermal power plants systematization and automation. The proposed approach is applied successfully to safety assessment, which improves the level of the safety management.
