建筑工人安全能力提升策略系统动力学仿真
System dynamics simulation of construction workers'safety competency improvement strategy
摘要
Abstract
To effectively enhance the safety competencies of construction workers and reduce safety ac-cidents in construction production,a construction worker safety competency system model was construc-ted based on information cognition theory.Regulatory factors were analyzed and safety competency im-provement strategies were proposed from the dimensions of safety culture,safety investment,and safety constraints.The utility of the safety competency improvement strategies was dynamically analyzed in quantitative form.Based on the system dynamics model of construction workers'safety ability,using safety investment strategy as a single factor to analyze,the dynamic characteristics of the core variables of each subsystem as time functions under different dimension promotion strategies were obtained.The results show that throughout the entire simulation cycle,the regulatory factors of safety culture strategy,safety investment strategy,and safety constraint strategy increase by 20％respectively,and the level of safety capability increase by 7.79％,9.46％,and 5.87％,respectively.It is found that the investment and safety competency benefits have the characteristics of time lag effects and"diminishing returns to scale".In addition,the improvement cycle for risk perception and decision-making competency is lon-ger and is greatly affected by safety culture strategy,while safety execution competency fluctuates great-ly within the simulation period and is mainly influenced by safety investment strategy.The research re-sults can further provide a basis for optimizing improvement strategies and predicting safety competen-cies.关键词
