Modelling is an activity that is found in every domain of research and science, and takes place even when we are not aware of it. Information Technology Aspects of Product and Process Modelling presents a model-centred approach focusing on distributed development and use of autonomous intelligent software models, particularly the efficiency of the models, and their interaction and integration into distributed autonomous intelligent systems. It considers the viewpoints of many different experts: the modeller, engineer, system architect, software developer, and users of the models and as such will be bought by all these people.
