Improving MBSE models using human performance simulation

It is important to recognize the human as an integral part of the system and its performance during systems development. However, systems engineers (SEs) currently fail to properly integrate the human into the system. This research aimed to improve system models by incorporating the human into modeling efforts. A set of Model-Based Systems Engineering (MBSE) models were created to describe an example scenario involving a virtual remotely-piloted aircraft simulation. When creating the models, some assumptions were made about the human from a SE´s perspective. In order to verify if these assumptions were realistic, a human-focused model of the system was created using the Improved Performance Research Integration Tool (IMPRINT). Running simulations in IMPRINT uncovered fallacies in some of these assumptions, thus demonstrating the value of incorporating the human into system models and reemphasizing the human as part of the system.
