Human Computer Interface


UCDS offers a full line of consulting services to evaluate your current plant condition, make realistic and achievable recommendations for improvement and aid you in implementing our recommendations. An integral part of this line is a set of human-computer interface (HCI) services providing guidance on industry standards and best practice. These services can be used to:

  • Assess the current state of your site’s human-computer interface, benchmarking it versus ASM® recommendations and industry Best Practices.

  • Perform Workshops to educate facilities on Best Practices in Human-Computer Interface design

  • Develop a detailed Human-Computer Interface Style Guide covering all aspects of Best Practices in situational awareness and cognitive processing, including delivering Training to your facility on proper implementation

A poorly implemented interface adds to workload, increases frustration, stress, and confusion, and can ultimately impact safety, reliability, production, and profitability. A properly implemented human-computer interface can reduce operator work load, improve situational awareness, and aid the operator in preventing minor deviations from becoming major incidents.

A properly implemented Human-Computer interface will also work hand in hand with Alarm Management initiatives. Better presentation of information to the operator improves overall situation awareness. This helps offset the perception operators frequently have that elimination of alarms from the DCS will reduce their ability track the status of the plant.

Recent research has identified that well implemented human-computer interface can improve operator performance in problem detection and resolution by as much as 25%. This reduces the amount of time the plant is running at less than optimal efficiency, thus improving the bottom line. This also reduces operator stress and improves employee relationships.

The Human-Computer Interface Assessment and human-computer interface style guide provide a rational and structured basis for ensuring all areas of importance relating to the human-computer interface are successfully addressed.

Based on this we offer the following services:

We are also happy to provide customized services based on any specific client requirements.

Technical

UCDS has in-depth experience in designing control rooms and modifying existing field shelters. Our process is compliant with the ISO 11064 Ergonomic Design Standard for Control Buildings. We interview management, supervision and a significant group of the operators to understand functional requirements, what works well in the existing environment, and identification and correction of problems with the existing design.

Situation Awareness

Abnormal situations encompass a range of events outside the “normal” plant operating modes, e.g. trips, fires, explosions, toxic releases or just not reaching planned targets. In the past incidents such as Piper Alpha, Milford Haven, Flixborough, Texas City and the 2003 northeast electrical blackout have all been attributed, at least in part, to a fundamental lack of good situational awareness. Early work of the Abnormal Situation Management Consortium® included a survey of the US petrochemical industry. Based on their research the consortium estimates industry losses of around $20 billion per year from abnormal situations, approximately equal to the total annual profits of that industry. Furthermore these studies indicate that companies achieving Best Practices in operations can improve productivity by 5-12%. To learn more Click Here

Fatigue Alertness Management

We have many customers looking to enhance their shift handover procedures and follow some of the Recommended Practices identified in the API documents; others are focusing attention on fatigue and fatigue countermeasures. We have great solutions for both these topics. For more details please contact Steve Maddox. To learn more Click Here

Behavior

User Centered Design Services promotes Behavior – Based Safety which is a process that helps employees identify and choose safe behavior over an unsafe one. Safety in the workplace is a combination of three measurable components – the person their environment, and their behavior. To learn more Click Here

About the Control Room Operator Performance Group

The purpose of this group is to share ideas and solutions that contribute to improving the performance of the control room operator. Abnormal situations can be managed safely and effectively if we provide our operators with the right training, workload, environment, and interfaces.
