Standards for safety critical software usually either mandate or recommend development
and assessment techniques which are deemed appropriate to reduce the risk of flaws in the …

The development of safety critical systems is guided by standards. Many standards require
the development of a safety case to demonstrate the acceptability of Safety Critical Systems …

The use of COTS software components within safety-critical systems has been suggested as
potentially bringing substantial benefits in terms of cost and time savings. However, the …

This paper addresses the problem of assessing the severity based on UML artifacts and
uses the cost of failures of software components and connectors as well as failures of system …

Abstract Artificial Neural Networks (ANNs) are employed in many areas of industry such as
medicine and defence. Their learning and generalisation capabilities make them highly …

This paper presents a framework for assessing different standards for computer-based
safety-critical systems. Key attributes of standards forming a basis for comparison are …

Commercial-Off-The-Shelf (COTS) software is increasingly being suggested for use in
systems development, for reasons including cost, functionality, useability, testedness …

Overlooked and poorly understood requirements are known to be a major cause of
softwarerelated failures in system designs. This paper describes the application of a process …

A variety of hazard analysis techniques have been proposed for software-based systems but
individually the techniques are limited in their ability to cope with system complexity, or to …

A Safety Integrity Level (SIL) is a statistical representation of the reliability of the Safety
Instrumented System (SIS) when a process demand occurs. SIL's are correlated to the …
