Build 7.5.1

  • Added the Multiple Systems with Event Codes data type, which allows for analysis of data with multiple systems with specified event codes using the Crow Extended model.
  • Added the Change of Slope methodology for developmental testing data using the Crow-AMSAA model.
  • Added the Statistical Test for Effectiveness of Corrective Actions for the Change of Slope methodology.
  • Added the functionality to group Multi-Phase Failure Times data.
  • Added the ability to obtain the equivalent single system for all applicable data types via the Transfer to New Data Type utility.
  • Improved the Event Report for data types that implement the event codes. This includes multi-phase data and the Multiple Systems with Event Codes data type.
  • Added the Crow Extended model for the Mixed data type.
  • Added the ability to specify effectiveness factors for BD modes that are fixed during the test for multi-phase data.
  • Added the functionality to obtain the plot data for the h(t) function plots choosing Plot > Copy Plot Data.
  • Added the System Operation plot for the Multiple Systems - Known Operating Times data type.
  • Examples for Multiple Systems with Event Codes, Change of Slope and Operational Testing have been added to the installation.

Build 7.0.3

  • Added a message to indicate too much data when switching from Advanced Systems view to Normal Systems view.
  • Fixed an issue with the 7th phase confidence bounds not properly displaying.
  • Corrected an issue transferring data to Weibull++ 7 when including the Failure Mode ID.
  • Added the ability to select which comment column will be used when transferring data to Weibull++ 7.
  • Fixed an issue with the multi-plots not correctly removing uncalculated data sheets when refreshing the plot.
  • Fixed an issue with Cramer von Mises test so the biasing of the Beta is correctly performed whether the data set is time or failure terminated.
  • Added the ability to calculate the Growth Potential when there are not any BDD modes at the final test phase.
  • Fixed an issue with the cumulative MTBF/failure intensity confidence bounds so that the correct number of degrees of freedom is used when the data is time terminated.

Build 7.0.2

  • Updated the default plot colors and appearance settings.
  • Resolved an intermittent issue associated with changing the default plot settings.
  • Fixed an issue where the Set Font dialog may have contained invalid fonts.
  • Added the ability to specify the start row when importing a file from Microsoft Excel.
  • Corrected confidence bound calculations associated with BD mode functions (Discovery Rate and MTBF BD Modes).
  • Fixed an intermittent issue with the MultiPhase plot projection calculations where the demonstrated MTBF was greater than projected MTBF.
  • Proper message is now displayed to indicate that 1/3 of the systems in repairable systems data must have a start time equal to zero.
  • Resolved an issue when grouping data into more than 64,000 intervals.
  • Fixed an issue on calculating using the Crow Extended model when importing the classification and event data in lowercase.
  • Corrected an intermittent issue when calculating the confidence bounds on the parameters.
  • Fixed an intermittent issue on the projection calculations when using multiple systems data.
  • Resolved an issue with the Growth Potential MTBF and Growth Potential Failure Intensity plots not retaining plot settings.

Build 7.0.1

  • Initial Release.
