In order to gain an improvement of safety or availability measures of the safety-relevant control system through employment of redundancy a redundant system has to comply with the requirement on independence of redundant parts. If the requirements on the independence of redundant parts are unfulfilled, then a common-cause failure can directly cause a hazardous state on a system level through its effects on multiple redundant parts. Identification of sources and quantification of the common… CONTINUE READING
