Resumé

"The fundamental objective of the combined safety and Reliability assessment is to identify critical items in the design and the choice of equipment that may jeopardize safety or availability, and thereby to provide arguments for the selection between different options for the system." Achieving safety and reliability has been one the prime objectives for system designers while designing safety critical system for decades. With growing environmental awareness, concerns, and demands, the scope of the design of reliable (and safe) systems has been enhanced to even small components as sensors and actuators. In the past, the normal procedure to address the higher demand for reliability was to add hardware redundancy that in turn increases the production and maintenance costs. Active fault-tolerant design is an attempt to achieve higher redundancy while minimizing the costs. In chapter 2 reliability and safety related issues are considered and described. The idea of introducing this chapter is to provide an overview of the concepts and methods used for reliability and safety assessment. The focus in chapter 3 is on fault-tolerance concept. Type of possible faults in components and customary methods for applying redundancy is described. Finally, the chapter is wrapped up by considering and describing the main subject, which is a formal and consistent procedure to design active fault-tolerant systems
