Modelling Uncertainty in Expertise

چکیده
Almost all approaches of model-based development of knowledge-based systems are lacking an explicit handling of uncertain knowledge. Based on a KADS-oriented model of expertise our paper presents a general framework that enables the representation of uncertainty in a structure of causality. Based on an existing model of expertise we introduce a separate model of uncertainty, whose elements are represented independent of speci c numerical processing methods. With this approach we got the foundations of a model-based framework integrating di erent kinds of uncertain information. The corresponding elements of both models are explicitly connected. The results of our work give prospects for a new understanding of knowledge engineering considering uncertainty in all steps of system development.

Modelling and Compensation of uncertain time-delays in networked control systems with plant uncertainty using an Improved RMPC Method
Control systems with digital communication between sensors, controllers and actuators are called as Networked Control Systems (NCSs). In general, NCSs encounter with some problems such as packet dropouts and network induced delays. When plant uncertainty is added to the aforementioned problems, the design of the robust controller that is able to guarantee the stability, becomes more complex. In...

متن کاملGraphical Modelling in Mental Health Risk Assessments
Probabilistic models can be a combination of graph and probability theory that provide numerous advantages when it comes to the representation of domains involving uncertainty. In this paper, we present the development of a chain graph for assessing the risks associated with mental health problems, which is a domain that has high amounts of inherent uncertainty. The Galatean mental health Risk ...
