Evaluating models in systems ergonomics with a taxonomy of model attributes

Area of Science:

• Ergonomics
• Systems Science
• Modeling and Simulation

Background:

• Understanding and evaluating models is crucial in system ergonomics.
• Models serve to represent knowledge for thinking, communication, and decision implementation.
• Existing models vary widely, from mental images to precise algorithms.

Purpose of the Study:

• To propose a novel taxonomy for classifying and evaluating models in system ergonomics.
• To define six independent attributes for assessing model quality.
• To provide a framework for selecting and refining models based on objectives.

Main Methods:

• Development of a taxonomy based on six independent model attributes: applicability to observables, dimensionality, metricity, robustness, social penetration, and conciseness.
• Definition of each attribute and its various levels.
• Illustration with examples of system ergonomics models.

Main Results:

• A structured taxonomy for model evaluation in ergonomics is presented.
• Each attribute provides a distinct dimension for assessing model characteristics.
• The taxonomy facilitates a more rigorous evaluation of model quality and suitability.

Conclusions:

• The proposed attribute taxonomy offers a systematic approach to evaluating models in system ergonomics.
• This framework aids in aligning model attributes with specific research or application objectives.
• The taxonomy enhances the understanding and effective use of models within the field of ergonomics.
