对数字化主控室操纵员在监视过程中的两类目标识别失误,目标识别延迟失误和目标识别失败失误进行了实验研究.通过模拟实验验证了这两种失误类型的存在,并且获得:目标识别延迟概率近似等于0.017,目标识别失败概率近似等于0.010.通过重复测量的方差分析发现,不同视野位置和不同离心距的目标识别失误率存在差异.并且随着离心距的增加,监视过程中目标识别失误概率也随之增大,拟合曲线方程为ln(y)=-5.55+0.024x.
Two target identification errors (target identification delay errors and target identification failure errors) of operator in the process of monitoring in digital main control room were experimental tested and measured. The simulation experiment results showed that target recognition delay error probability is approximately equal to O. 017, and the target identification failure error probability is approximately equal to O. 010. Anova for repeated measurement method found the significant difference of target recognition error probability between different field locations and different eccentricity. And the error rate of target recognition increased with eccentricity, the fitting function is:ln(y) =--6. 292+0. 214x.
