Reliability, Availability, Maintainability, and Testability (RAM-T)

 

Conduct various analyses related to the overall reliability of a design, as well as how the design is constructed to be maintained (maintainability and testability). The combination of these three sub-disciplines determines the overall availability of a design. Analysis capabilities encompass multiple engineering disciplines including: mechanical, electrical, hydraulic, etc. Analysis types and tasks include:

Reliability


 

  • Failure Modes, Effects, and Criticality Analysis (FMECA)
  • Failure Modes and Effects Analysis (FMEA)
  • Failure Reporting and Corrective Action System (FRACAS)
  • Physics of Failure (PoF)
  • Reliability Predictions
  • Mean Time Between Failures (MTBF)
  • Root Cause Analysis
  • RAM-T Case Development
  • Design Influence
  • Architecture Analysis for Inclusion of Reliability
  • Requirements Development and Decomposition
 

 

Maintainability


 

  • Mean Time to Repair (MTTR)
  • Maintenance Ratio (MR)
  • Design Influence
  • Architecture Analysis for Inclusion of Maintainability
  • Requirements Development and Decomposition
 

 

Testability


 

  • Analyze design capability to diagnose failures (Test Point Assessment)
  • Analyze design level to which the failure can be diagnosed (Ambiguity Group)
  • Design Influence
  • Architecture Analysis for Inclusion of Reliability
  • Requirements Development and Decomposition
 

RAM-T Tool Set

 

  • Isograph
  • RELEX
  • Reliasoft
  • Microsoft Suite
  • Requirements Database (DOORS, SLATE, RTM)
  • Templates for Analysis and Report Types
  • eXpress Design for Diagnostics Software
