Conceptual models are built with concepts and relationships between them to reach a unified view of domain problems. There many kinds conceptual developed in different modeling languages, such as class diagrams entity-relationship models. In this paper, the authors have specific meta-model following Ecore standard define These domain-specific can be automatically formalized ontologies using mod...

Model transformations are the core and research focus of MDA(model driven architecture). Nowadays, there are many model transformation approaches and tools, and the heterogeneity of them causes that the model transformation code can’t be reused easily and the cost of studying and using model transformation increases. To eliminate these shortcomings, inspired by model weaving technique, this pap...

Traditional Data Envelopment Analysis (DEA) models evaluate the efficiency of decision making units (DMUs) with common crisp input and output data. However, the data in real applications are often imprecise or ambiguous. This paper transforms fuzzy fractional DEA model constructed using fuzzy arithmetic, into the conventional crisp model. This transformation is performed considering the goal pr...

In Model Driven Engineering, bidirectional transformations are considered a core ingredient for managing both the consistency and synchronization of two or more related models. However, current languages still lack of a common understanding of their semantic implications hampering their applicability in practice. This paper illustrates a set of relevant properties pertaining to bidirectional mo...
