11.7.1 General concepts
The preceding section and chapters of this book have generally assumed that the failure of any one component is independent of the failure of any other. This assumption is usually made in the reliability analysis of most system. In practice, however, it is sometimes found that a system fails more frequently than the value predicted using this assumption of independence. In some cases it has been found that the probability of failure
