Word Processing Functions

This section presents the functions that can be entered in the Synthesis Workbook's word processing module in Weibull++ and ALTA by using the Function Wizard.

The Function Wizard must be used to initially add a function in the word processing module, as the functions are inserted as fields. After doing so, you may copy the function and change its settings.

The functions are grouped into the following categories:

General functions return basic information about the database, project and current user (e.g., project name and user name).

Format: [PROJECT]

Example: [PROJECT] returns the current project name.

Data source functions return values that are based on the analysis in a specified data source (e.g., reliability, failure rate and mean).

Format: [RELIABILITY(Source Number)(Time)]

Example: [RELIABILITY(1)(1000)] uses the analysis in associated data source 1 to return the reliability at 1,000 hours.

Confidence bounds functions return one-sided confidence bound values that are based on the analysis in a specified data source (e.g., bounds on reliability, failure rate and mean).

Format: [BOUNDREL(Source Number)(Time; Confidence Level)]

Example: [BOUNDREL(1)(1000;0.9)] uses the analysis in associated data source 1 to return the 90% one-sided confidence bound on the reliability at 1,000 hours.

Table functions return values in a table format that are based on the analysis in a specified data source (e.g., probability of failure for a range of time, reliability for a range of time and parameter bounds).

Format: [TBLREL(Source Number)(Start Time;End Time;Time Increment)]

Example: [TBLREL(1)(100;500;50)] uses the analysis in associated data source 1 to return a table containing calculated reliability results at 100 hours and every additional 50 hours until 500 hours has been reached (i.e., 100, 150, 200, 250, etc.).
