application of agent based model in simulation of stakeholder’s behavior is slightly a new method for modeling of complicated systems that include autonomous agents interacting with each other. recent numerical achievements have made the applications of agent based models possible in various fields. these applications range from modeling of human progress and destruction of past civilizations t...

Ontology is a comprehensive knowledge model which enables the developer to practice a “higher” level of reuse of knowledge. Typically, different modeling languages are employed in different phases of software development of a knowledge-based system. In order to achieve knowledge instead of software reuse, we propose forging a closer mapping between the knowledge and software models in the devel...

An approach for tight coupling of process models and software development tools — with the metaphor of component-based software development environments — supporting “eXecutable Process Models” (XPM) is presented. In this paper, we focus on the direction from the components of a software development environment towards the process models in order to automatically acquire process model informati...

This paper presents an extension of role-based access control model with the use of usage control concept together with its representation using the Unified Modeling Language (UML). The presented model is developed for role engineering in the security of information system. The presented implementation of URBAC (Usage Role-Based Access Control) model consists in creation of security profiles fo...

In the UML, use cases are used to define coherent units of functionality associated with classes, subsystems, or systems. Two principal purposes that use cases serve are specifying the functionality the system will provide and providing a basis for developing test cases for the system being specified. This paper discusses issues that arise when using use cases as the basis for model-based testi...

In model-based testing, one of the biggest decisions taken before modelling is the modelling language and the model analysis tool to be used to model the system under investigation. UML, Alloy and Z are examples of popular state-based modelling languages. In the literature, there has been research about the similarities and the differences between modelling languages. However, we believe that, ...

Significant evidence suggests that there is increasing demand for information technology oriented students who have exposure to Object-Oriented (OO) methodologies and who have knowledge of the Unified Modeling Language (UML). Object-oriented development has moved into the mainstream as the value of reusable program modules is becoming more evident. Building blocks such as software components an...

Agent UML is a graphical modeling language for describing multiagent systems but until now, it has not been applied to real-world applications. The aim of our project is to apply Agent UML to Supply Chain Management. This project has several objectives: (1) it allows us to discover which diagrams have to be enhanced, modi ed or created and, (2) it allows us to de ne a methodology based on Agent...

We recently introduced 3D Modeling with Silhouettes [1], a new sketch-based modeling approach in which models are interactively designed by drawing their 2D silhouettes from different views. The core idea behind our approach is to limit the input to 2D silhouettes, removing the need to explicitly create or position 3D elements. Arbitrarily complex models can be constructed by assembling them ou...
