Systems whose failure can lead to the damage of property or the environment, or loss of human life are regarded as safety-critical systems. It is no longer adequate to build safet...
SIL's (Safety Integrity Levels) are used by IEC 61508:1998 [1] to characterise the required functional safety of computer control systems. For example, SIL 4, the highest rat...
Preliminary work on the development of measures appropriate for the safety domain is reported. Measures are expressed in the style of the Practical Software and Systems Measuremen...

We perform a Why-Because Analysis (WBA) starting from the information in the Executive Summary of the U.S. DoD Aircraft Accident Investigation Board report on the shootdown of two ...
The decomposition of complex systems into manageable parts is an essential principle when dealing with complex technical systems. However, many safety and reliability modelling te...
This paper describes a method for performing safety analysis on an Integrated Modular Avionics system in a manner which supports the incremental development and change of system c...
Architectural based approaches to designing software are motivating changes in the way software is developed for safety-critical systems. These new approaches allow developers to d...
Abstract. Motivated by our work on object-oriented Content Management, this paper proposes an extensible formal framework for delta and merging strategies, each applicable to a spe...
The data models of a series of 11 configuration management systems—of varying type and complexity—are represented using containment data models. Containment data models are a s...
Individual organisations as well as industry consortia are currently defining application and domain-specific languages using the eXtended Markup Language (XML) standard of the W...
