Safety critical systems are pervasive in modern society. Financial systems, transportation systems, medical record retrieval systems, and air traac control systems all could potentially threaten economic, property, or personal safety. However, this class of safety critical system is not amenable to the existing approaches to achieving safe software. Hence a new approach to software safety is ne...

the adoption of food safety systems (fsss) is of major significance in the food industry, and that approach is especially of more promience in dairy and meat processing firms. in this study the aim was to introduce the factors affecting the probability of adoption of fsss in the dairy and the meat processing plants in aydin, western turkey. it was observed that ten out of twenty-eight dairy bus...

As software-intensive systems become more pervasive, more and more safety-critical systems are being developed and deployed. Yet when most people think about safety requirements, they think of safety-critical functional requirements, which are requirements that have critical safety ramifications if not correctly implemented. However, there are actually four major...

Fault Tree Analysis is a traditional deductive safety analysis technique that is applied during the system design stage. However, traditional fault trees often suffer from a lack of formal semantics to check the correctness or consistency of the descriptions. This is especially a problem in safety-critical system analysis. To overcome this limitation, we propose a novel formal fault tree constr...

While safety engineering standards define rigorous and controllable processes for system development, safety standards’ differences in distinct domains are non-negligible. This paper focuses in particular on the aviation, automotive, and railway standards, all related to the transportation market. Many are the reasons for the said differences, ranging from historical reasons, heuristic and esta...

This monograph focuses on a proposal for a testing model in safety critical systems. Due to the large scope of these systems we have focused on the system testing and we have included requirements for testing the communication subsystem. After establishing the theoretical background for testing, we have analysed the issues of safety critical systems. In this analysis we have also focused on ind...

Currently, hardware designed and certified for safety-critical systems is one important building block for any safety-critical application. Such hardware provides the detection of execution errors. However, many modern safety-critical applications, like autonomous driving, require features and performance levels that are not available from safety-certified hardware. One solution to this problem...

The emergence of safety-critical systems and their much desired institutionalisation involves domainand applications-independent issues that, in some sense, can be related to the interdependent issues of knowledge, language, and ethics. The design, maintenance, upgrading and decommissioning of existing networks for carrying, for example, water, gas or oil, are good examples where the triumvirat...

The use of COTS (Commercial-Off-The-Shelf) software in safety-critical systems is increasing due to the potential for reduced development costs, reduced development time, reduced time to market and increased quality of the end product. Developing safetycritical systems using COTS software raise some new challenges. This essay investigates the appropriateness of using COTS in safety-critical sys...

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 safety-critical systems based on the control of errors and failures alone. Safetycritical systems must also deal with securing the data that is used in their operation. While safety and security engineering have evolved sep...
