Enterprises of the transportation sector must face a huge competition. So, an efficient vehicles fleet management is crucial. The present work proposes a generic model adapted to the monitoring of a fleet of vehicles. This model is able to describe the information chain and the different decisional processes associated to the monitoring architectures. On a first “vehicle” level, each vehicle and also its context (cargo, user, environment and task) are considered. The vehicle composition is modelled according to a holonic hierarchy. On a second “fleet” level, data collected from all vehicles are analysed. The model is then applied to the monitoring of trucks tyres for a transport application of dangerous substances.
