摘要: 为分析有限理性建筑工人的认知过程,探讨完全信息和不完全信息情景下建筑工人的风险感知经验、冒险程度、行动执行水平等3种认知因素对其不安全行为的影响;构建4阶段认知模型,以某工程项目的建筑工人为实证对象,设定模型的初始参数,采用Matlab模拟仿真。结果表明:相比于不完全信息,完全信息下建筑工人认知的更新频率更快,工人不安全行为和危害数量的比例更低;一定程度上经验可以帮助工人认知风险,但过于依赖风险感知经验容易导致不安全行为的发生;越理性、任务执行水平越高的工人,其不安全行为的发生比例越低。

Abstract: In order to analyze cognitive process of construction workers with bounded rationality, influences on their unsafe behaviors of three cognitive factors, namely risk perception experience, risk degree and action execution level of construction workers were explored in both situations of complete information and incomplete information. A four-stage cognitive model was constructed then and Matlab simulations were conducted with construction workers of an engineering project as empirical objects and initial parameters being set. The results show that construction worker's cognition is updated more frequently and and there is a smaller proportion of unsafe behaviors and hazardous events in case of complete information compared with that of incomplete information. Experience can help workers recognize risks to a certain extent, but excessive reliance on risk perception experience can lead to unsafe behaviors. The more rational workers are and they stronger executive power they have, the fewer unsafe behaviors there will be.

Key words: construction worker, unsafe behavior, cognition, bounded rationality, incomplete information
