Application Examples for RGA

ReliaSoft’s RGA reliability growth and repairable systems data analysis software provides a comprehensive platform for the application of reliability growth models for the analysis of both developmental test data and fielded repairable systems. Some of the many useful applications include the ability to:

• Quantify reliability growth achieved with each successive design prototype.
• Determine the feasibility of achieving reliability goals with a given test/fix strategy.
• Calculate optimum overhaul times and other results for fielded repairable systems without the detailed data sets that would normally be required for repairable system analysis.

These examples demonstrate some of the types of analyses you can perform with this application. For additional product documentation, including the Quick Start Guide, visit the Synthesis eDocs & ePubs Library..

Example 1:

Simple MTBF Determination

This example shows how to solve for the demonstrated MTBF using interval data that were collected from five helicopters during the final test phase.

See Example

Example 2:

Working with Grouped per Configuration Discrete (Success/Failure) Data

This example examines the analysis of a “one-shot” system undergoing reliability growth development testing during which different tests are performed on different design configurations.

See Example

Example 3:

Developmental Testing with Corrective Actions Implemented During the Test and Delayed Fixes

This example is based on the paper An Extended Reliability Growth Model For Managing And Accessing Corrective Actions by Dr. Larry Crow, presented at the 2004 RAMS. It examines developmental testing on a product during which identified failures are ignored, corrected during the test or corrected after the test.

See Example

Example 4:

Fielded Systems Analysis

This example illustrates how to use the Crow Extended model with the Fleet data type to analyze data from fielded systems. It is shown that the beta = 1 assumption is not valid when the Repairable data type is used to analyze the data set, but it is valid when the Fleet data type is used.

See Example

Example 5:

Analyzing Software Reliability Growth

This example examines a typical software reliability growth scenario. When the time required to reach the failure intensity goal is initially higher than expected, a subset of the full data set is analyzed instead.

See Example

Example 6:

Multi-Phase Planning and Analysis

This example illustrates how to use the mission profile folio to group failure times data based on specified convergence points. This strategy can help to achieve more balanced results from analysis with the Crow Extended model.

See Example

Example 7:

Mission Profile

This example illustrates how to use the mission profile folio to group failure times based on specified convergence points. This strategy can help you achieve more balanced results from analysis with the Crow Extended model.
