基于熵权可拓理论建筑施工项目安全风险评价

针对当前建筑施工项目中安全风险管理现状,综合考虑人员、材料、机械设备、技术、环境、管理等六大影响因素,构建安全风险评价指标体系,通过采用熵权理论计算指标权重,引入物元可拓理论综合评价模型,得到建筑施工项目安全风险等级。最后通过实例验证了模型的可靠性和科学性,为建筑施工项目安全风险评价提供借鉴。

Evaluation of security risk in building construction project based on entropy weight and extension theory

Focusing on the current situation of security risk management in building construction project, security risk evaluation indexes system is established through comprehensive consider six major factors as follow personnel, materials, mechanical equipment, environment and management. The weight of each index can be gotten by information entropy, applying extension theory to evaluate risk and the level of risk in building construction project is obtained. Finally, an example is provided to verify reliability of the method, giving some reference for security risk evaluation of building construction project.
