Active fault diagnosis based on stochastic tests

Niels K. Poulsen, Henrik Niemann (2008)

International Journal of Applied Mathematics and Computer Science

The focus of this paper is on stochastic change detection applied in connection with active fault diagnosis (AFD). An auxiliary input signal is applied in AFD. This signal injection in the system will in general allow us to obtain a fast change detection/isolation by considering the output or an error output from the system. The classical cumulative sum (CUSUM) test will be modified with respect to the AFD approach applied. The CUSUM method will be altered such that it will be able to detect a change...

Advanced approach for the public transportation regulation system based on cybercars

Asma Melki, Slim Hammadi, Yves Sallez, Thierry Berger, Christian Tahon (2010)

RAIRO - Operations Research

In the last decade, the authorities require the use of safe, comfortable vehicles to assure a door to door aspect with respect of environment in the urban context. In this paper, we propose an advanced approach of transport regulation where we integrate cybercars into a regulation process as an alternative in disruption cases. For that, we propose an ITS architecture including public transportation and cybercars into the same framework. We will show that collaboration between these two systems...

Advances in model-based fault diagnosis with evolutionary algorithms and neural networks

Marcin Witczak (2006)

International Journal of Applied Mathematics and Computer Science

Challenging design problems arise regularly in modern fault diagnosis systems. Unfortunately, the classical analytical techniques often cannot provide acceptable solutions to such difficult tasks. This explains why soft computing techniques such as evolutionary algorithms and neural networks become more and more popular in industrial applications of fault diagnosis. The main objective of this paper is to present recent developments regarding the application of evolutionary algorithms and neural...

Affectation de véhicules aux routes dans un système de transport multi-école.

Ana M. Cobes, Albert Corominas (1990)

Qüestiió

Este artículo describe una parte del sistema TRESCA para la organización del transporte escolar en Andorra. Una vez determinadas las rutas a ofrecer, conviene asignarles los vehículos para minimizar los costes. El algoritmo que se ha concebido establece las secuencias de rutas de acuerdo con el modelo de Orloff, con una programación lineal entera y con un subalgoritmo glotón.
