Reliability Requirements and Analysis

Note: Information shown in the UML class diagram illustrates information represented by the DEX. Not all the information contained in the UML class diagram is required for every data exchange.

Figure 16 — UML Model of Reliability Requirements and Analysis

Information shown in the UML class diagram is as follows:

Reliability Availability and Maintainability Characteristics contains logistics considerations, maintenance, and reliability characteristics of the item under analysis. It also contains narrative information associated with logistics considerations.

Reliability Availability and Maintainability Indicator Characteristics contains reliability and maintainability characteristics of the item under analysis categorized by comparative analysis, allocated, predicted, or measured values.

War Peace Reliability Availability and Maintainability Indicator Characteristics contains reliability and maintainability characteristics of the item under analysis categorized by wartime/peacetime scenarios and comparative, allocated, predicted, or measured values.

Failure Mode and Reliability Centered Maintenance Analysis contains failure mode information and reliability centered maintenance analysis results associated with the item under analysis failure modes.

Failure Mode Task identifies the maintenance task(s) that are required to correct the identified failure mode of the item under analysis and preventative maintenance tasks that are deemed applicable and effective through an RCM analysis.

Failure Mode Indicator Mission Phase Code Characteristics contains Failure Mode Effects Criticality Analysis results associated with the item under analysis categorized by failure mode and mission phase/operational mode.

Reliability Availability and Maintainability Criticality sums up the failure mode criticality numbers related to the failure modes of an item within specific safety hazard severity classification and mission phases.

Mission Phase Operational Mode identifies the mission phase/operational modes that the new system/equipment is expected to experience during normal operation.

Task Requirement contains task level information. It also contains information about personnel and training aspects of the task.
