    Modellierung überbetrieblicher behandlungsprozesse durch objekt-petrinetze
    (Springer, 2005) Sarshar, Kamyar; Loos, Peter
    Clinical processes are often performed by the cooperation of different healthcare organization. But even that for modeling of such processes the object Petri nets can be used, they often lack of intuitive comprehensibility. This contribution presents an interpretation of object Petri nets which assigns abstract net elements to real objects of the healthcare domain. By doing this it helps domain user to apply this Petri net type to the modeling of clinical processes. The application of this approach is demonstrated.

    Zur Identifikation von Strukturanalogien in Datenmodellen
    (Springer, 2005) Fettke, Peter; Loos, Peter
    On the one hand, data models decrease the complexity of information system development. On the other hand, data models causes additional complexity. Recently structural analogies are discussed as instruments reducing the complexity of data models. This piece of research presents a procedure to identify structural analogies in data models and demonstrates its performance by analyzing Scheer’s reference model for industrial enterprises (Y-CIM-model). The proposed procedure is based on formalizing data models within set theory and uses a quantitative similarity measure. The obtained results show both identical and very similar information structures within the Y-CIM-model. Furthermore, ways of dealing with the identified structural analogies are discussed from an analysis and software design perspective.
