Embodiment Construction

[0013] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0014] figure 1 It is a structural schematic diagram of the present invention. As shown in the figure: the fuzzy comprehensive evaluation method of the urban natural disaster level provided by the invention comprises the following steps:

[0015] S1: Construct urban natural disaster evaluation factor set U.

[0016] S2: Create a comment set V.

[0017] S3: Establish a single-factor evaluation fuzzy matrix R.

[0018] S4: Carry out fuzzy comprehensive evaluation.

[0019] The urban natural disaster evaluation factor set U includes selecting parameter indexes and determining index weights.

[0020] The selection of the parameter index is screened through the method...

Abstract

The invention proposes a fuzzy synthetic evaluation method for the urban natural hazard grade. Aiming at multi-disaster targets, the method comprises the steps: giving evaluation criteria according to the law of fuzzy relation and expert advices; carrying out the quantification and synthetic evaluation of fuzzy factors reflecting natural disaster risks; building a membership function through the construction of a grade fuzzy subset; proposing the fuzzy synthetic evaluation method for the urban natural hazard grade; and evaluating the urban natural hazard grade. The method gives full consideration to a plurality of influence factors of natural disasters, and solves a difficulty of hazard grade division caused by fuzzy concept medium transition, and greatly improves the decision-making efficiency.

Description

technical field [0001] The invention relates to the fields of automation and fuzzy mathematics, in particular to a fuzzy comprehensive evaluation method for urban natural disaster levels. Background technique [0002] After the 1980s, the study of geological hazards began to break through the traditional research model, and the study of disaster grade assessment has made significant progress, but there are still some problems. Due to the large amount of uncertainty and ambiguity in the natural disaster system, the terminology indicating the level of disasters is relatively confusing, the evaluation index systems used are very different, and the calculation methods and classifications are also inconsistent. The evaluation process and evaluation criteria are always mixed with people's subjective understanding. In terms of disaster risk assessment goals, there are more assessments for single disasters, but less comprehensive assessments. [0003] Therefore, there is an urgent...
