基于AHP模糊综合评价的建筑工人不安全行为传播性研究

Research on the Spread of Unsafe Behaviors of Construction Workers Based on AHP fuzzy Comprehensive Evaluation

如今建筑行业施工现场事故频发,而人的不安全行为是造成事故的主要原因。通过评价建筑工人不同种类不安全行为的传播性强弱,可以控制不安全行为传播。选择特定行为作为研究对象,综合考虑既有建筑工人不安全行为传播影响因素的指标体系,利用层次分析法(AHP)确定指标权重,再利用模糊综合评价法确定各行为的传播性强弱。结果表明:使用错误姿势的不安全行为传播性最强,其次是交通管理类、个人防护类,而脚手架类、起重作业类、个人状态类传播性相对较弱。

Nowadays,accidents at the construction site occur frequently,while people’s unsafe behaviors are the main cause of accidents.The spread of unsafe behaviors can be controlled by evaluating the spread strength of different types of unsafe behaviors of construction workers.This paper presents a framework to assess the spread level of unsafe behaviors.The framework incorporates four analyses:selecting some specific unsafe behaviors as the research objects,building an index system of factors affecting the spread of unsafe behaviors of construction workers,using Analytic Hierarchy Process(AHP)to determine the index weights,and using fuzzy comprehensive evaluation method to determine the spread of each unsafe behavior.The results show that the spread level of using wrong postures is the highest,followed by traffic management,personal protection,while scaffolding,lifting operations,and personal status are relatively weaker.
