模糊测度理论在施工现场安全目标决策中的应用

Application of fuzzy measure theory in safety objective decision of construction site

由于施工现场安全状态综合评价是一个多层次、多指标的复杂分析评价问题,既要考虑单个因素、单个项目反映的施工安全性态,又要考虑施工现场多个因素、多个体系反映的整体安全性态,为此提出了安全状态评价集的表示方法。通过对安全判据的分析,结合模糊集理论和模糊测度理论,研究施工现场安全评价判据的表示方法、结论表达及综合评价等不确定因素的处理方法,应用模糊集理论,对施工现场安全管理状况做出评价,建立了施工现场安全综合评价模型,应用实例表明,该模型是可行的。

Comprehensive evaluation of construction site safety condition is a complex multi-hierarchy and multt-in- dex evaluation problem. Not only the local safety behavior based on a single measurement points and a single item but the entirety safety behavior based on multiple measurement points and multiple items should be considered. Based on the analysis of safety evaluation criterion, combining fuzzy set theory and fuzzy measure theory, the repre- hensive methods of the construction site safety management safety criteria and treatment methods of uncertain factors were studied. The comprehensive evaluation model of construction site safety management was established using the fuzzy measure and fuzzy integration theories. The application showed that it is practical and effective.
