Reliability Data

Reliability data consists of entering the reliability of the equipment at different times or stages. An example is shown in Figure 3.12. In this case, the process is monitored at pre-defined time intervals and the reliability is recorded. The reliability can be computed by a simple ratio of the number of units still functioning and the number of units that entered the test stage or by using Life Data Analysis and related methods.

Models for Reliability Data

The following models can be used to analyze reliability data sets. Models and examples using different data types are discussed in later chapters of this on-line reference.
