A System Reliability Analysis is made up of records and links as defined by the System Reliability data model. At a conceptual level, groups of records and links make up the main elements of the analysis, as defined in the following list:
System Reliability analysis: A collection of Scenarios, Resources, and simulation results that make up a given analysis. A System Reliability Analysis is represented by a System analysis record, which stores identifying information about the analysis and is linked to other records that make up the analysis.
Scenario: A representation of one design option for a given system. A Scenario is represented by a System Scenario record, which contains all the identifying information for the Scenario and is linked to other records that help define the Scenario. Each Scenario can contain the following components:
Diagram: A logical, visual representation of the physical structure of a system, including all the elements in the system and the connections between them. A Diagram might be the representation of a system as it physically exists at your work site, or it might represent a variation of a physical system developed for the purpose of analyzing how changes to the system could impact maintenance and production costs. Each Scenario contains one Diagram.
Risk: A component that identifies a specific way that a piece of equipment or location can fail and specifies the consequences of the failure and includes Time to Failure (TTF) and Time to Repair (TTR) distribution data. A Risk is represented by a System Risk record, which contains all of the identifying information for the Risk.
Action: A component that identifies a specific operation that can be performed against a piece of equipment or location. Actions include condition-based maintenance, procedures, redesigns, time-based maintenance, and training, and may or may not mitigate Risks. Actions are represented by records in the System Condition Monitor, System Inspection, System Preventive Maintenance, or System Special Action families, which contain all the identifying information for the Action.
Global Event: A component that groups together Actions that require a system shutdown. Scheduling a Global Event can make a system more efficient by providing more time in which to run the system while still allowing maintenance and other Actions to take place. A Global Event is represented by a System Global Event record, which contains all the identifying information for the Global Event.
Resource: A component of a System Reliability Analysis that associates a cost with an occurrence of an Action or Risk. Resources are defined for a System Reliability Analysis and are represented by a System Resource record.
