Requirements engineering is an important phase in a system's life cycle. When poorly
performed, various problems may occur, such as failures, cost overrun and delays. The …

The increasing complexity of software systems makes Requirements Engineering activities
both more important and more difficult. This article is about user requirements development …

The aviation system has experienced an increasing demand over the last decade since it is
considered one of the optimal means of transportation. As a result of this increasing …

Activities of specification, analysis and design of real-time systems (RTS) are highly

The discrete event systems specification (DEVS) formalism supports the object-oriented
(OO) specification of discrete event models in a hierarchical, modular manner. If a system …

A robust health care system is crucial to reducing patient stress and contributing to economic
growth. The future of the health care industry depends upon a reliable and efficient system to …

The paper presents the Embodied Agent-based Robot control system modelling Language
(EARL). EARL follows a Model-Driven Software Development approach (MDSD), which …

Requirement Engineering demands a granular level of requirement specifications with key
objectives, design constraints and relevant artefacts. There exist some structured …
