This paper presents a crisis response simulation model architecture combining a discrete-event simulation (DES) environment for a crisis scenario with an agent-based model of the response organization. In multi-agent systems (MAS) as a computational organization, agents are modeled and implemented separately from the environmental model. We follow this perspective and submit an architecture in ...

The complexities and costs associated with preserving the nation’s bridge infrastructure demand innovative approaches to analysis of data and prediction of future bridge conditions. Several Bridge Management systems (BMS) have come into existence following the ISTEA act of 1991. The policy analysis module of BMS systems developed is restricted to analytical methods. With the availability of mod...

The diagnosability analysis proposed for Discrete Event Systems (DES) can be extended to Hybrid Systems (HS) which are systems with combined discrete and continuous behavior. In this paper we propose an approach based on the combination of the diagnosability of the underlying DES and the distinguishability of the continuous modes of the HS. The main idea is to build an observer of the underlyin...
