Current complex products such as transportation systems usually dispose of an elaborate monitoring, control and diagnosis system. Very often such intelligent systems rely on models of the product (e.g. mathematical models). Such models are stored in the control units, in diagnosis and/or safety systems of the product and can therefore be referred to as “in-product models”. It is important to note that several models of the product are generated during the product development of this system. One example for an in-product model might be a monitoring system for condition based service. Such systems rely on sensory information such as from vibration sensors and need to determine when service is necessary. Similarly, in product development engineers investigate vibrations of the product and need to determine how much vibration is admissible. Today, the generation of the two kinds of models is frequently done in separate departments and is usually not connected in a systematic manner. This paper discusses possibilities to integrate the generation of product development models and “in-product models” using the product example oil free compressor for braking systems of trains.
