چکیده

Aspect-oriented approaches have recently been proposed to address the problem of specifying dynamic object-based systems, by depicting the various roles of the objects separately. In this paper, we consider an approach based on the observable behavior of objects and propose a specification formalism for reusable object interfaces with input/output-driven assumption-guarantee predicates. The formalism supports compositional reasoning and exchange of object identities between objects in an environment where the number of objects is unbounded.

A Multi-Formalism Modeling Framework: Formal Definitions, Model Composition and Solution Strategies

In this paper, we present a multi-formalism modeling framework (abbreviated by MFMF) for modeling and simulation. The proposed framework is defined based on the concepts of meta-models and uses object-orientation to overcome the complexities and to enhance the extensibility. The framework can be used as a basis for modeling by various formalisms and to support model composition in a unified man...

Modeling and Evaluation of Stochastic Discrete-Event Systems with RayLang Formalism

In recent years, formal methods have been used as an important tool for performance evaluation and verification of a wide range of systems. In the view points of engineers and practitioners, however, there are still some major difficulties in using formal methods. In this paper, we introduce a new formal modeling language to fill the gaps between object-oriented programming languages (OOPLs) us...

Introduction of Viewpoints in Conceptual Graph Formalism

To represent knowledge in a context of several experts, it is interesting to model the multiple perspectives that different experts may have on the objects handled in their reasoning. The concept of a particular perspective called viewpoint, is already used in the field of object oriented representation or in the field of databases conception. Taking inspiration of research made in object orien...
