Verification and validation (V&V) for human performance models (HPMs) can be likened to building a house with no bricks, since it is difficult to obtain metrics to validate a model when the system is still in development. HPMs are effective for performing trade-offs between the human system designs factors including number of operators needed, the...

Human performance modeling (HPM) has been effective for determining crew designs. Crew design includes determining the number of operators needed, the role of automation, and member task responsibilities required to operate a system. Crew models are built for target systems under development to better inform the design and the needs of each operato...

Building software can be compared to building a house. The software product must start with defining requirements prior to writing the first line of code. Likewise, with building a home, a home buyer must approve a design with the architect, and work to establish the requirements before laying the first brick. Unfortunately, in the Department of De...

Human performance modeling (HPM) can be an effective tool to use for determining crew designs. Crew design includes determining the number of operators needed, the role of automation, and member task responsibilities required to operate a system. Without effective measures of performance and thresholds for assessing success, design decisions from H...
Chapter
For human system interfaces involving supervisory control with a high degree of automation, maintaining situation awareness (SA) can be an important and challenging operator task. Additionally, maintaining SA for these types of operator tasks can be a significant percentage of the operator workload to execute their mission. This paper presents a me...

... The psychometric method relies upon the administration and scoring of multiple cognitive performance tests. Such as Galy's relationship between mental workload factors and cognitive load types [7]; Schmorrow's foundations of augmented cognition [8]; Steinberg Workload's model for situation awareness [9]. This approach has made a strong influence on applied psychological research [10]. ...
