Using traditional semantic data modeling, multi-level modeling can be achieved by
representing objects in different abstraction hierarchies, namely classification, aggregation …

The traditional two-level modeling approaches produce accidental complexities when
modeling multiple abstraction levels. This problem is addressed by the emerging multi-level …

In this article we show how to extend object constraint languages by reflection. We choose
OCL (Object Constraint Language) and extend it by operators for reification and reflection …

Conceptual modelling has a lengthy history. In the context of software engineering, over the
last three decades, conceptual modelling has moved from largely being used for data …

In the paper a system construction of the risk management principle is given where the
system parameters are represented with fuzzy sets, and the grouped risk factors' values give …

In a manufacturing environment, engineers and scientist often need to access and reason
about general types of manufacturing methods without complex specifications and numbers …

Since its introduction in the mid-sixties (Zadeh, LA,(1965)), fuzzy set theory has gained
recognition in a number of fields in the cases of uncertain, or qualitative or linguistically …

L'essor de l'Internet et l'évolution des dispositifs communicants ont permis l'intégration du
monde informatique et du monde réel, ouvrant ainsi la voie à de nouveaux types …

Since its introduction in the mid-sixties (Zadeh, LA,(1965)), fuzzy set theory has gained
recognition in a number of fields in the cases of uncertain, or qualitative or linguistically …

The article has given an overview of the scaling of the universe of the risk management
systems' input parameters, which can also be well-managed in a fuzzy environment. From …
