The idea system for car diagnosis developed by Centro Ricerche Fiat is one of the most successful practical applications of automated diagnosis. However, idea is based on functional dependency models that have to be built ad-hoc for each speci c device to be diagnosed. Thus, the models are not easily reusable and this increases the cost of building new applications. In this paper we show how models of the sort used by idea can be derived automatically from a library of generic component models, given a description of the structure of the device to be diagnosed. In this way we can reconcile two goals: (i) exploiting libraries of component models that can be reused in many applications (both in diagnostic applications and for other tasks), cutting down the cost of developing a new application and (ii) changing the idea system as less as possible. The latter is a major goal since idea is a fully engineered system, installed in more than 1500 car repair centers in Italy and integrated with on-board and o -board equipment.
