In many knowledge-based systems the used knowledge is distributed among several knowledge sources. Knowledge maintenance of such systems has several challenges to be met. This paper gives a short overview of a maintenance approach using so-called Case Factories to maintain knowledge sources and considering the dependencies between these sources. Furthermore we present a concept how our maintena...

AIMS is a knowledge-based system for learning and teaching support within the context of distance education. It is aimed not only at enhancing learner's conceptual knowledge in a specific subject area but also at providing knowledge verification tools for the teacher. The system can be used to aid learning and teaching in different subject areas and to provide user-oriented support in searching...

The progress in computer simulation tends to simulate complex systems governed by “internal models”, i.e. sophisticated activities of computing technique in real time flow. Independently of that, computer simulation needs the object-oriented programming and the agent-based paradigm for constructing “external models” of complex systems that are being designed. Thus the progress tends to use mode...

In this paper we present a biologically-inspired approach for mission survivability (considered as the capability of fulfilling a task such as computation) that allows the system to be aware of the possible threats or crises that may arise. This approach uses the notion of resources used by living organisms to control their populations. We present the concept of energetic selection in agent-bas...

Guiding vehicles to their destination under dynamic traffic conditions is an important topic in the field of Intelligent Transportation Systems (ITS). Nowadays, many complex systems can be controlled by using multi agent systems. Adaptation with the current condition is an important feature of the agents. In this research, formulation of dynamic guidance for vehicles has been investigated based...

How does someone react when he faces a critical situation in his life? In this paper we present an initial initial implementation architecture based on a simulation model described in [10] In our model we mainly consider the interactions between a person concerned and factors like his environment and his own abilities. Using the empolis information access suite, we currently implement our model...

This paper presents the utilization of the multi-agent platform Geamas through the Biomas application for the collective management of animal wastes. The complexity of the scenarios under study gives rise to many unpredictable behavioral schemas whose analyses necessitate a simulation approach. In the present article we describe the whole set of concepts in use in multi-agent systems modeling a...
