This project will help to determine the right information to include on an APC graphic and how can we better train our console operators to use that information.
The research teams from Applied Decision Science and ShadowBox will be building on the results of a previous project “Cognitive Task Analysis for Advanced Process Control” to develop modifications to current best practices for APC Graphics and APC training in an effort to better support Console Operators understanding of APC functions.
APC systems are becoming more complex to improve process safety and lessen environmental impacts. The increased complexity of these systems is making it more challenging for operations to understand what is happening behind the scenes, to detect when they are malfunctioning and to troubleshoot the associated problems that may arise. This project will strive to improve both graphics and training best practices in order to better support console operator understanding of APC functions.
What characteristics of the operator-process system (displays, training, job aids, etc.) are needed to enable the console operator to maintain situation awareness while using APC? Within these characteristics, what are the detailed requirements (e.g., what skills and knowledge need to be trained, what information should be on the graphics and how should it be presented)?
Advance process control is a program that continuously monitors key variables and adjusts numerous other variables to maximize plant or unit performance. Due to its complexity, APC often is considered a “black box” by many operators. Phase I “Cognitive Task Analysis for Advanced Process Control” studied a COP member site APC application. Operators, engineers, and supervisors were interviewed to develop an understanding of key decisions operators must make, and what makes these decisions difficult. An output of the Phase I project was a CTA guide for COP Members.
Task 1: Cognitive Task Analysis on Operation of Advance Process Control
The deliverable from task 1 is a briefing detailing the methods, findings, and implication for interface design and training, created and delivered jointly by ADS and ShadowBox.
Task 2: Human-Machine Interface Design Recommendations
The deliverable from Task 2 is a set of wireframe drawings depicting human-machine interface design recommendations, led by ADS. If possible, we will work with Emerson to ensure wireframes are at a level of specificity to assess feasibility and usability in a simulator facility.
Task 3: Training Design Recommendations
The deliverable from Task 3 will be led by ShadowBox and is covered in the project CAT for APC, Phase II - Training.
Task 4: Refined Guide to Conducting Cognitive Task Analysis
The deliverable from Task 4 is a refined Guide to Conducting CTA, led by ADS.
