Demands for embedded real-time software in large telecommunication systems are becoming higher and higher now. Therefore, it is crucial in such systems that the software must be designed with good architectures. In order to build such architectures, it is necessary to apply appropriate real-time analysis and design methods as well as specify the system's special requirements. In this paper, we ...

In this paper we focus on the most critical portion of the transition from an user-oriented requirements description to an object-oriented domain model, namely the mapping of use cases onto classes and operations in the class model. Since thorough documentation of if and how both models co-operate is rarely found, requirements traceability is aggravated and systematic testing for completeness r...

In our scenario-based method for software architecture-level modifiability analysis of business information systems, we use architectural views to determine and express the effect of change scenarios. We distinguish four architectural views. We used the Unified Modeling Language (UML) notation to formalize the information captured in these views. This paper reports on the experience we gained i...

This paper focuses on the research of project information management for the urban planning engineering company of the author, starting from the analysis of demand, this paper puts forward the system's functional and nonfunctional design target, summarizes the overall system design and module design ideas, then completes the design and implementation of project management system, and introduces...

The process of quality assurance in higher education is a complex process requiring many of the arrangements. This process consists of several stages; the most important stage is the evaluation. This paper provides the unified modeling language diagrams (UML) for the quality assurance evaluation process in any higher education institution. Also, the prototype implementation of this system is di...

The Virtual Reality (VR) technique based on computer graphics has been rapidly evolving over the years. VR has emerged to set a trend for developing applications and virtual environments. This paper introduces the trend and features through case studies about the game contents system for immersive interaction among these virtual reality techniques. The proposed methodology utilizes the Unified ...

The scientific research problems can be easily modeled by using the modeling language and it is necessary for getting the errors in the solution at the early stages of the development/ implementation of solution of the scientific research problem. Many of the software companies are using the object-oriented modeling language for this purpose. A planning for new town in a country is very complex...

This paper examines system engineering (SE) and object-oriented (OO) methodologies and then shows both that SE is inherently OO and that OO languages such as the Unified Modeling Language (UML) may be used to document the user’s needs in a manner that can be used by developers. The paper also suggests a next generation tool concept that can be used to hold both user and developer representation...

The Multi-Echelon Distribution Supply Chain (MEDSC) is a multifaceted structure, focusing on the integration of all factors that involved in the overall distribution process of finished products to the customers. The growing interest in multi-echelon distribution systems has highlighted the need to adopt an appropriate approach to ensure the efficient management of their complexity. While there...

In this paper, we will demonstrate how the Unified Modeling Language (UML) can be used to describe agent interaction protocols. The approach that is presented in this paper does not propose major enhancements or completely new diagrams but instead it relies on existing UML elements that are part of the standard. This conformity with the base UML is a major advantage of the idea as it prevents a...
