基于可变模糊云的既有玻璃墙安全预警

为了科学有效地进行既有玻璃幕墙的安全预警，考虑指标权重的不确定性以及指标出现极端数值的情况，提出了一种基于组合权重与可变模糊云的既有玻璃幕墙二维预警方法。首先，以实际工程为背景，通过安全风险因素的识别，构建了一套定性与定量指标相结合的既有玻璃幕墙安全预警体系；随后，基于可变模糊集理论改进了逆向云发生器，提出了可变模糊云算法并完成了指标预警云的生成；接着，在正态云与熵权法的基础上，提出了信息云组合权重法，继而实现了权重的组合；最后，通过虚拟云与模糊熵的计算，分析了既有玻璃幕墙的安全状态，实现了既有玻璃幕墙的二维预警与警情状态的可视化。研究结果表明：与其他预警方法相比，该方法不仅实现了警情的基本判断，还能提出更为有效的安全处理意见，从而为既有玻璃幕墙的安全管理提供参考。

Based on Combined Weight and Variable Blurry Clouds of Existing Glass Curtain Wall Safety Warning

Aiming at the problem of uncertain index weight and extreme value of early warning index in safety early warning of existing glass curtain wall, a two-dimensional early warning method of existing glass curtain wall based on combination weight and variable fuzzy set theory is proposed. This method first takes the actual project as the background, and based on the identification of safety risk factors, takes the existing glass curtain wall components as the division basis, and selects 25 factors such as the bearing capacity of the panel, the hardware status of the opening window, and the appearance of the stressed components to build the safety risk early warning system of the existing glass curtain wall. Subsequently, quantitative indicators are assigned based on the variable fuzzy set theory, and the qualitative indicators are quantified based on the triangular fuzzy number theory, and the variable fuzzy cloud of the early warning indicator is generated by the improved reverse cloud generator. Then, based on the idea of cloud theory and entropy weight method, the information cloud combination weight method is proposed to complete the combination of subjective and objective weights. Finally, through the calculation of the virtual cloud model, the one-dimensional warning and visualization of the security state of the existing glass curtain wall are realized. In addition, in order to further measure the complexity of the early warning level, fuzzy entropy is also introduced for auxiliary judgment, so as to complete the two-dimensional early warning model of the existing glass curtain wall. Compared with other early warning methods, the calculation results of this model are more scientific and accurate, which can not only realize the basic judgment of the police situation, but also put forward more effective safety processing opinions, thus providing a basis for the safety management of the existing glass curtain wall.
