An Approach to Modeling and Analyzing Human-Centric Systems and Its Application

Human-centric design is based on the psychological and physical needs of the human users. Model-driven engineering provides formal model to be analyzed. How to combine formal model with human-centric design methodology is a crucial issue and yet it has not been settled. In fact, the difficulty of this problem is lacking of formal representations of the human-centric property. The intention of our research is to provide some new approaches to effectively model and analyze the human-centric system. So we proposed model-based methodologies for modeling and analyzing the human-centric system, which aim to use hierarchical model framework to effectively build systems. This paper mainly addresses two issues. The first one is the modeling of human-centric system by the hierarchical model framework. Then we selected the automatic train control braking system as the application to build hierarchical model based on five corresponding submodels and provide the new braking modes and new braking strategies.
