description: Human-in-the-Loop Decision Support in Process Control Rooms Dataset

Overview

This repository contains a comprehensive dataset aimed at assessing cognitive states, workload, situational awareness, stress, and fatigue in human-in-the-loop process control rooms. The dataset includes objective and subjective measures from various data collection tools such as NASA-TLX, SART, eye tracking, EEG, Health Monitoring Watch, surveys, and think-aloud situational awareness assessments. Additionally, it incorporates data from a simulation of a formaldehyde production plant based on participants' interactions in a controlled control room experimental setting.

Purpose

The primary objective of this dataset is to compare the performance and safety outcomes of different groups of participants exposed to varying decision support tools. These tools include alarm prioritization, paper-based vs. digitized screen-based procedures, and an AI recommendation system. Statistical analysis was performed to compare the outcomes among the groups.

Key Features



Subject Area: Chemical Engineering, Control and Safety Engineering, Human Factors and Ergonomics, Human-Computer Interaction, and Artificial Intelligence

Data Format: Raw, Analyzed, Filtered

Type of Data: CSV File (.csv), Matlab File (.mat), Excel (.xlsx), Table

Data Collection: The dataset contains behavioral, cognitive, and performance data from 92 participants, including system data under each participant from three scenarios, each simulating a typical control room monitoring, alarm handling, planning, and intervention tasks and subtasks. The participants consented to participate on the test day, after which the researchers trained them. They performed functions under three scenarios, each lasting 15 - 18 minutes. During these tests, the participant wore a watch for health monitoring, including an eye tracker. They were asked situational awareness questions based on the SPAM methodology at specific periods within 15 minutes, especially at the 6th, 8th, and 12th minutes. These questions assessed the three levels of situational awareness: perception, comprehension, and projection. This feedback collection process on situational awareness differed for one of the groups that used an AI-based decision support system. The question for this group was asked right after specific actions. Therefore, for the overall study, the following performance-shaping factors are considered: type of decision support system, alarm design, procedure format, AI support, communication, situational awareness, cognitive workload, interface design, experience/training, task complexity, and stress. In both cases, communication was excluded as a factor considered in the first and second scenarios based on this absence. The data collected was normalized using the Min-Max normalization.


Potential Applications

The dataset provides an opportunity for various applications, including:



Developing human performance models and process safety models

Developing a digital twin simulating human-machine interaction in process control rooms
