过去二十年，香港建造业的安全投资增加了300%；然而，十年来，它的事故率一直稳定在50%左右。在此背景下，研究人员发现安全投资与安全绩效之间的因果关系尚无定论。本研究采用基于主体的模型，采用一种非传统的自底向上的方法，将建筑工地的安全绩效作为一个复杂系统的结果进行研究，该系统由工地、建筑工人个体和不同安全投资之间的相互作用所定义。本研究的重点不是寻找安全投资与安全绩效之间的绝对关系，而是提供一个实用的框架来研究不同的安全投资与不同参数（如人为因素和环境因素）的相互作用如何影响安全绩效。因此，我们可以在不同的建设方案下确定具有成本效益的安全投资，以提供最佳的安全性能。(C) 2016 Elsevier Ltd.版权所有。
The construction industry in Hong Kong increased its safety investment by 300% in the past two decades; however, its accident rate has plateaued to around 50% for one decade. Against this backdrop, researchers have found inconclusive results on the causal relationship between safety investment and safety performance. Using agent-based modeling, this study takes an unconventional bottom-up approach to study safety performance on a construction site as an outcome of a complex system defined by interactions among a worksite, individual construction workers, and different safety investments. Instead of focusing on finding the absolute relationship between safety investment and safety performance, this study contributes to providing a practical framework to investigate how different safety investments interacting with different parameters such as human and environmental factors could affect safetyperformance. As a result, we could identify cost-effective safety investments under different construction scenarios for delivering optimal safety performance. (C) 2016 Elsevier Ltd. All rights reserved.
