目的：本研究的目的是调查潜在的好处，似然报警系统（LAS）在二进制报警系统（BAS）在多任务环境。背景：与BAS的使用相关的几个问题，因为它们中的大多数生成大量的假警报。操作员对系统失去信任，忽略警报或在其他信息可用时交叉检查所有警报。第一种行为危害安全，而第二种行为降低生产力。LAS代表了一种替代方案，它应该改善操作员的注意力分配。方法：我们调查了LAS和BAS的双任务范例，有和没有可能交叉检查警报与原始数据信息。参与者对系统的信任，他们的行为，以及他们在警报和并发任务中的表现进行了评估。结果：报告的信任，遵守警报，并在警报和并发任务的性能较高的LAS比BAS。交叉检查选项导致两个系统的警报任务性能提高，BAS的并发任务性能降低，但在LAS条件下不会发生这种情况。结论：LAS改善了被试在两个不同任务之间的注意分配，从而提高了警觉任务和并发任务的绩效。当LAS与交叉检查选项结合使用时，可实现最大性能，以验证具有其他信息的警报。应用：在安全相关的多任务环境中使用LAS而不是BAS，同样有可能提高安全性和生产率。
Objective: The aim of the current study was to investigate potential benefits of likelihood alarm systems (LASs) over binary alarm systems (BASs) in a multitask environment. Background: Several problems are associated with the use of BASs, because most of them generate high numbers of false alarms. Operators lose trust in the systems and ignore alarms or cross-check all of them when other information is available. The first behavior harms safety, whereas the latter one reduces productivity. LASs represent an alternative, which is supposed to improve operators’ attention allocation. Method: We investigated LASs and BASs in a dual-task paradigm with and without the possibility to cross-check alerts with raw data information. Participants’ trust in the system, their behavior, and their performance in the alert and the concurrent task were assessed. Results: Reported trust, compliance with alarms, and performance in the alert and the concurrent task were higher for the LAS than for the BAS. The cross-check option led to an increase in alert task performance for both systems and a decrease in concurrent task performance for the BAS, which did not occur in the LAS condition. Conclusion: LASs improve participants’ attention allocation between two different tasks and therefore lead to an increase in alert task and concurrent task performance. The performance maximum is achieved when LAS is combined with a cross-check option for validating alerts with additional information. Application: The use of LASs instead of BASs in safety-related multitask environments has the potential to increase safety and productivity likewise.
