The “Operating Requirements” portion of the reliability element dialog allows you to define logical relationships between elements using a logic tree:
Logic trees are defined using a number of different types of nodes (e.g., AND gates, OR gates).
In order for a reliability element to be operable, all of its defined requirements must be met. By default, no external requirements are defined, and all of the element’s failure modes are added as internal requirements.
The topics below describe the details of how you can create logic trees for a reliability element.
