This project belongs to the existing housing safety management field, and conducts in-depth research on housing safety assessment and guarantee technology. 1. On the basis of summarizing previous research results and the accumulation of topics accumulated by the Academy of Housing for many years, six categories of housing safety hazards are summarized. Through research on six categories of safety hazards, the influencing factors of various safety hazards are extracted and used as the basis for on-site testing and house safety assessment. 2. The classification standards for house safety levels, house safety hazards, and various influencing factors and a fuzzy comprehensive evaluation method for house safety assessment are proposed. The subject establishes a mathematical analysis model for fuzzy comprehensive evaluation of house safety assessment, uses analogy method to determine the membership functions of each potential safety hazard influencing factor, studies and uses analytic hierarchy process to determine the weight coefficients of each influencing factor, and analyzes the level of potential safety hazards through the weighted average fuzzy operator model., and finally comprehensively evaluates the safety level of the house. 3. The verification of engineering examples shows that the fuzzy comprehensive evaluation method for house safety is an advanced safety assessment method. It has the advantages of simple and intuitive evaluation method, and the evaluation results are informative, more reasonable and highly operable. It will be widely applicable in future house safety assessments. 4. The "Technical Guidelines for Housing Safety Assessment in Shanghai City" has been compiled, which provides effective technical support for the adoption of the fuzzy comprehensive security assessment method for houses based on safety hazards and lays a foundation for the application of assessment methods. 5. A housing safety assessment decision-making system software has been compiled to improve the efficiency of housing safety assessment work. 6. Research on housing safety guarantee technology and developed a guarantee technology for full-process control and management. 7. The level novelty search report shows that the subject has generally reached the international advanced level.
Through the research of house safety assessment and security technology,《Shanghai City house safety assessment technology guide》and house safety assessment decision-making system software compiled can be applied to all levels of government agencies, real estate management departments and property management units, can be more widely used in house safety assessment and security management work, and provide technical support for house safety assessment and security management in Shanghai City.
The promotion of this achievement will promote the improvement of the management level of housing safety management departments and related departments. There will be rules to follow in future management, timely identify the crux of housing safety, deal with and resolve them in a timely manner, eliminate safety hazards, reduce housing safety accidents, and reduce people's property losses. It has good social and economic benefits, as well as broad application prospects.
