Embodiment Construction

[0060] The present invention provides a multiple linear regression fire risk assessment method based on big data, which uses a multi-attribute assessment method, the model is widely used in complex systems due to its convenience and robustness, and the heuristic process of associating these attributes constructs a Robust fire risk assessment system. This multi-factor comprehensive risk assessment method determines the main factors affecting the risk, solves the data standardization problem of each factor, and completes the establishment of the risk assessment model.

[0061] (1) Construct a hierarchical structure model of fire risk factors

[0062] In the multi-factor comprehensive risk analysis, the selection and determination of factors are very important. The factors affecting the fire safety of social units in the field of fire protection include five aspects: (1) fire hazard source; (2) building fire protection; (3) personnel situation; ( 4) Fire safety management of soc...

Abstract

The invention relates to a multivariate linear regression fire risk assessment method based on big data, which is used in the field of data processing and analysis. Comprises the following steps of: (1) constructing a hierarchical structure model of fire risk factors; (2) dividing a building fire risk grade; (3) Establish the evaluation model R=WTX; (4) Constructing the data sample of risk assessment machine learning; 5, calculate that weight W according to the sample, and establish a fire safety fire risk assessment model R=WTX; (6) Calculating the attribute value of the building to be evaluated according to the step (4.1), and comparing the risk value calculated by the model established in the step (5) with the risk grade divided in the step (2) to obtain the risk grade of the building.This method adopts multi-attribute evaluation method, realizes the quantitative evaluation of fire risk grade, and comprehensively evaluates the fire safety management risk of social units.

Description

technical field [0001] The invention relates to a fire risk assessment method based on big data and machine learning, belonging to the field of data processing and analysis. Background technique [0002] With the rapid development of today's society, fire has already become a disaster that cannot be ignored. How to actively detect and warn in advance, and how to reduce the fire risk in social units has always been the basis of socialized fire protection work. With the development of science and technology, fire risk assessment methods based on big data, cloud computing, and artificial intelligence continue to mature. Through the analysis and mining of massive historical data, a scientific fire risk assessment system has been established. Through the fire risk assessment of social units, determine their fire safety levels, discover risk items, guide them to improve fire safety mechanisms, and improve fire safety levels, thereby reducing risks, protecting people's lives and pr...
