Complexity in Safety-Critical Systems

On Complexity Reduction of User Interfaces for Safety-Critical Systems

Control and communication systems used at power plants or incineration facilities offer various graphical visualizations of the physical parts of the site; however, they rarely provide sufficient visualization of the signal data. There is the problem, that such facilities contain 10,000 or more data acquisition points; each of them continuously sending data updates to the control system (once i...

Java in Safety Critical Systems

Until recently, the preferred language for developing safety critical applications has been Ada, but this is beginning to change. The number of developers willing to program in Ada is diminishing, while the complexity of applications is increasing. Where as C and C++ are poor alternatives to Ada, realtime Java specifications have benefited from strong cross fertilisation from the Ada community,...

Safety - Critical Systems Design

Introduction Embedded systems are like normal desktop systems in that they have functional requirements, that is, functions that the system is expected to perform, such as moving the robot arms. One of the ways embedded systems differ from desktop systems is that they also have significant quality of service (QoS) requirements as well. In real-time embedded systems, for example, timeliness and ...

Designing Safety-Critical Computer Systems

40 Computer Designing Safety-Critical Computer Systems T he ubiquitous computer is firmly established as the electronic component of choice for designing systems that control safety-critical applications. Such applications can be found everywhere: aircraft fly-by-wire controls, oil and chemical processing, hospital life-support systems, manufacturing robotics, and countless other commercial and...
