Towards Architectural Connectors for UML

Fernando Orejas; Sonia Pérez

The notion of architectural connector was developed by Allen and Garland [1] as an important concept for the design of software architectures. In this paper, based on previous work introducing a generic approach for the definition of component-based concepts, we study how architectural connectors and components can be defined for class and sequence diagrams as a first step for applying this approach to full UML. In particular, the case of sequence diagrams is studied with some detail. A case-study of a lift system is used to illustrate these ideas.

Loose Semantics of Petri Nets

Julia Padberg; Hans-Jörg Kreowski

In this paper, we propose a new,loose semantics for place/tran- sition nets based on transition systems and generalizing the reachability graph semantics. The loose semantics of a place/transition net reflects all its possible refinements and is given as a category of transition systems with alternative sequences of events over the net. The main result states that each plain morphism between two place/transitions nets induces a free construction between the corresponding semantic categories.

A Formal Framework for the Development of Concurrent Object-Based Systems

Leila Ribeiro; Fernando Luís Dotti; Roswitha Bardohl

In this paper we present a framework for developing concurrent object-based systems. The framework is based on graph grammars and includes techniques for specification, simulation, animation and verification.

A Formal Description of the Basic Concepts of System Theory for Transportation

Eckehard Schnieder; Jörg R. Müller

In this paper some of the basic concepts of system theory are presented in a formal way. This is done with the help of the formal modeling language petri-nets. An example out of the transportation is used to illustrate the discussed concepts.
