Functional Safety of Software-Based Critical Systems
نویسنده
چکیده
The international standard for functional safety of systems involving programmable-electronic components, IEC 61508, has been valid since the late 1990's, and Version 2 has just become valid [IEC10]. The scope of the standard is, generally, everything except avionics and medical equipment. It is based on the approach, novel at that time, of quantifying and reducing risk until it is acceptable, rather than the then-prevailing paradigm of finding out everything that could go dangerously wrong with a system or subsystems and fixing it so that it doesn't, an approach deemed Sisyphean.

Design patterns for safety-critical embedded systems
Over the last few years, embedded systems have been increasingly used in safetycritical applications where failure can have serious consequences. The design of these systems is a complex process, which is requiring the integration of common design methods both in hardware and software to fulfill functional and non-functional requirements for these safety-critical applications. Design patterns, ...
متن کاملAssessing and enhancing functional safety mechanisms for safety-critical software systems
More and more devices of our everyday life are computerized with smart embedded systems and software-intensive electronics. Whenever these pervasive embedded systems interact with the physical world and have the potential to endanger human lives or to cause significant damage, they are considered safety-critical. To avoid any unreasonable risk originating from the failure of such systems, strin...

متن کاملDefining Requirements on Domain-Specific Languages in Model-Driven Software Engineering of Safety-Critical Systems
Domain-specific languages are designed and used to assist software development in various domains. Safety-critical systems such as aviation systems, railway control systems and nuclear power plants require certified software by law. This paper focuses on domain-specific languages that are used to represent a physical reality and to describe the behavior of a control software as a finite state m...
متن کاملA novel fuzzy multi-criteria decision-making methodology based upon the spherical fuzzy sets with a real case study
The choice of roll stabilization system is critical for many types of ships. For warships where operational activities are fast and the concept of time is very effective, determining the most appropriate of these systems is of particular importance. Some operations, such as the landing of the helicopter on board, are critical for naval ships. Unwanted rolling motion makes this difficult. In add...
