Use the Accelerated Life Test Plan outline to define the model structure and the type of inspection for your design.
Figure 22.16 Initial ALT Design Window
Number of accelerating Factors
One accelerating factor
Select for a design with one factor.
Two accelerating factors - main effects model
Select for a two factor design for a main effects model
Two accelerating factors - interaction model
Select for a two factor design for a model that contains main effects and an interaction term.
Monitoring Type
Continuous Monitoring
Select for a design with exact failure times recorded. Failure times beyond the length of the test are right censored.
Monitoring at Intervals
Select for a design with units inspected for failures at intervals. Failure times are interval censored. Enter the number of inspections, the time of the first inspection, and the time between inspections. For inspection intervals that are irregular, you can change the inspection times later in the Design Choices outline.
