Analysing the behaviour of physical systems often leads to realise that a natural representation consists in building mixed continuous / discrete models. Multimodels or hybrid models are adapted representations for complex physical systems by introducing transitions (smooth or not) between local behaviours. This paper presents some technical points dealing with the determination of the time transition from one local model to another one. More generally, our purpose is to estimate, at each time, the state of the associated process.
