This research work has started in 1988 and continues. It is done mainly in collaboration with Associate Professor Ashok K. Goel. This work has focussed on two basic issues in reusing the problem solving knowledge of an intelligent system for a new problem.

The adaptive modeling methodology is used for design problem solving in the domain of engineering devices. In order to capture the knowledge of designing a device, several Functional Models are developed. These models map the physical attributes of devices onto the goals of the designer. This work is conducted through several projects which are listed below.


Functional Modeling:

In order to capture the knowledge of designing a device, so that it can be reused to design new devices, several Functional Models are developed. These models map the physical attributes of the devices onto the goals of the designer. These functional models include Structure, Behavior and Function (SBF) models, Environmental Structure, Behavior and Functional(ESBF) models and Methods, Strategies and Task (MST) models.

Model-based Diagnosis:

Diagnosing multiple-diseases in human body is a very difficult task to model. This work addresses this problem by simulating the disease progress within the body by using a set of prototypical qualitative disease processes. Given symptoms, these processes are selected and a disease progress is simulated. The simulation that explains the largest number of symptoms present in the patient is the diagnosis.
