行为形成因子与人为差错模式的定性关联分析

为揭示人为差错的发生规律以便有效管理人为差错,研究行为形成因子与人为差错模式间的对应关系。将行为形成因子作为情景环境的表征,在SRK(skill,rule,knowledge)模型的基础上,将认知功能的效能分为3种指标:全面性、准确性和效率,将认知功能与效能指标相结合得到人为差错模式的分类。在此基础上,根据经验详细分析行为形成因子对认知功能3种效能指标的影响,得到行为形成因子与人为差错模式的关联关系表格。该关联关系是定性的,包含密切关联、重要关联、一般关联和没有关联4种关联程度,不但可以用于人为差错事件的调查,而且可以用于人为差错模式的预测。

Qualitative Correlation Analysis between Performance Shaping Factors and Human Error Mode

In order to disclose the law of human error and control it effectively,the correlation between performance shaping factor and human error mode is researched.Performance shaping factor is introduced to represent the scenario.Based on the SRK model,the quality of cognitive function is divided into three performance indices,which are completeness,accuracy and efficiency.By synthesizing cognitive functions and performance indices,a new taxonomy for human error mode is provided.Based on it and according to experiences,the influences of performance shaping factor on the three performance indices of cognitive functions are analyzed in details,respectively,and the qualitative correlation between performance shaping factor and human error mode is constructed,which can be represented by a table.The correlation degrees in the table include "extreme","important","general" and "void".With the help of the correlation table,not only the retrospective analysis of human error but also the prospective analysis can be conducted.
