Cyber-Physical Systems are embedded computers that control complex physical processes and components while cooperating as agents in distributed networks. Due to the scale and complexity of the interactions that occur within cyber-physical systems, requirements traceability strategies that are accurate and easy to manage are hard to implement and maintain. However, the information traces provide is...
This paper describes the EDIS business messaging architecture, which is a modern, lightweight system that is used in numerous companies. It explains the requirements for such a system, the problematic issues that have to be dealt with, and also some aspects of the wider context of e-commerce. Furthermore, it compares the presented architecture to similar systems like, for example, MS BizTalk and discusses...
Requirements engineering is the first stage in the development of any system. For safety-critical industrial systems like smart-grids, we must ensure that requirements are properly elicited, defined, analyzed and managed. This paper adapts the requirements framework developed in the CESAR European project, called the CESAR requirements meta-model, to support all aspects of requirements engineering...
The IEC 61499 Function Block standard describes an architecture to support the development and reuse of software components for distributed and embedded industrial control and automation systems. Often distributed over heterogeneous execution platforms, IEC 61499 applications are highly re-configurable; users can map individual function blocks to run on any available device. However, the standard...
