Create ALT Design Tables

When your accelerated life test (ALT) design is finished, make the ALT design and create the test plan and data tables.

Make Test Plan

Creates a data table where each row corresponds to a distinct design setting. The table shows the acceleration factor design settings and the number of units to test at those design settings.

Make Table

Creates a data table that you can use for recording your failure time data.

For Continuous Monitoring, the table contains a row for each unit to be tested and the design settings for that unit. If a unit fails during the experiment, record the unit’s failure time in the Failure Time column and a 0 in the Censored column. If a unit does not fails during the experiment, record the final inspection time in the Failure Time column and a 1 in the Censored column.

For Monitoring at Intervals, the table contains a row for each design setting and time interval combination. The time intervals are defined by the Start Time and End Time columns, which are based on the Inspection Times entered in the Design Choices section. For each setting and time interval, record the number of units that failed in the Number Failing column.
