    The term 'system architecture' has many slightly different definitions and/or uses. A system architecture becomes essential when a number of subsystems are being integrated. Integration is not simply concerned with the communication between the subsystems but also any conflicting assumptions inherent in each subsystem. The Converge-SA methodology fits each definition of system architecture into one of four levels of abstraction. The resultant system architecture provides the basis for a family of working and workable systems. The paper discusses levels of system architecture and its use in safety-related telematics systems.

    The word 'model' must be one of the most overused in the English language. It can mean an ideal, an abstraction or a cardboard replica. It may be presented as a diagram, printed text, or a set of mathematical formulae. It may represent a physical structure, a logical structure, a sequence of events, or a set of causal relationships. This article examines the various meanings of 'model' and asks if the usages of the term in software engineering jargon are always meaningful. It reviews several types of software model, including life-cycle models, control-flow and data-flow models, design paradigms such as object-orientation and functional decomposition, quality models, and models of system behaviour, and outlines their deficiencies.

    A process, known as the goal directed approach, has been developed which ensures that the most appropriate and effective combination of techniques is used to identify potential problems in safety-critical software. The process is illustrated by application to the Hercules C-130J aircraft static code analysis project. The objective of this project is to identify safety threatening anomalies in the safety critical software for resolution before the first flight of the aircraft. View full abstract»

    The influence of programming technology on reliability and on safety, and why the industry seems unable to learn from its mistakes, apparently preferring to chase pots of gold with object oriented and such like written on the side, is discussed. View full abstract»

  • 3D printing with metals

    Rapid prototyping is a technique that 'prints' a component, instead of manufacturing it in traditional terms, by using materials ranging from photopolymers to thermoplastics, including paper. Since these materials are in most cases not suitable for assessment purposes a new approach has been created. It has a similar 'build up' technique but uses metal as raw material. The process entails the use of a gas metal arc fusion welding robot which deposits successive layers of metal in such a way that it forms a 3D solid component. This process can also be considered a manufacturing process for low volume production. The technique presented in this article tries to solve the main limitations of traditional rapid prototyping processes and incorporates some new techniques for automating the process and these have proved to be extremely successful.
