Data Types

Reliability growth analysis can be conducted using different data types. The following data types can be utilized in the RGA software, as shown in the Data Type Expert in Figures 3.1 and 3.2:

Developmental Testing (Reliability Growth Data)
- Time-to-Failure Data
  - Failure Times
  - Grouped Failure Times
  - Multiple Systems (Known Operating Times)
  - Multiple Systems (Concurrent Operating Times)
  - Multiple Systems with Dates
  - Multiple Systems with Event Codes
- Discrete Data
  - Sequential
  - Sequential with Mode
  - Grouped per Configuration
  - Mixed Data
- Multi-Phase Data
  - Failure Times
  - Grouped Failure Times
  - Mixed Data
- Reliability Data
Fielded Systems
- Repairable
- Fleet

This chapter explores and examines these possible data schemes and outlines the available models for each data type.
