2019

In version 11.1 F000, the PTC Windchill Quality Solutions product suite is rebranded to Windchill Risk and Reliability. In this version, some of the licenses are combined into bundles (for more information, see the Windchill Risk and Reliability 12.0 Release Notes document on PTC website). In the recent versions from 11.0 onwards, the support for 217Plus Quanterion Standard, Telcordia Issue 4, EPRD 2014 and NPRD 2016 is provided. Additionally, this release extends support to two FMEA applications with single sign-on (SSO).

2015

PTC Windchill Quality Solutions 11.0 enhances the Data Engine API and supports an extension for ThingWorx. This extension allows ThingWorx users to connect to Windchill Risk and Reliability to access FRACAS, FMEA, and FTA data to develop ThingWorx mashups and applications. Additionally, in the Enterprise Edition, the number of System Tree subtable fields and FMEA Worksheet fields has been increased.

2013

PTC Windchill Quality Solutions 10.2 implements the FTA module in the web application, introduces an additional FMEA action data level, and provides a special Problems subtable for restricting access to only team members on a record-by-record basis. With proper permissions, Enterprise users can associate the following with a problem: FRACAS incidents, FMEA actions, FTA diagrams, RBD diagrams and blocks, and system tree items. Additionally, this release extends support for associating problems with Windchill change management objects to the desktop. Several maintenance releases have since introduced many features and performance improvements for better supporting global FMEA and FRACAS initiatives.

2012

PTC Windchill Quality Solutions 10.1 introduces new features to import quality-critical characteristics from Creo, visually distinguish hardware and software elements in the system tree, and associate problems with Windchill CAPA and change management objects. Additionally, this release extends support for the creation of personal Start pages and global dashboards to the desktop application, incorporates the SAE ARP4754 and ARP4761 fault tree methodology, imports CAFTA fault trees, and implements Telcordia Issue 3 for reliability predictions and NPRD 2011 for both reliability predictions and RBDs (reliability block diagrams). Additionally, in the Enterprise Edition, 15 FMEA Table subtables have been added and LDAP-compliant server support has been upgraded. Additionally, administrators can view and manage Project and file properties and set up System file folders from the web application.

2011

The Relex 2011 M080 update begins the rebranding to Windchill Risk and Reliability. This update includes tree rollup calculations, counter calculations, and the red-lining of changed data on reports. Additionally, the Enterprise Edition supports the highlighting of changes to parts inserted from Windchill PDMLink or MPMLink and 15 new FMEA Tree Items subtables, which can be used to construct p-diagrams. Additionally, the web application implements full Microsoft Silverlight functionality, Google-like search capabilities, and a new dashboard. In November, PTC Windchill Quality Solutions 10.0 completes the rebranding and adds many more subtables and data fields, especially for the Enterprise Edition. Additionally, the Enterprise Edition supports not only Microsoft Active Directory (AD) servers but also LDAP v3-compliant servers. Its web application, now named Windchill Risk and Reliability Web Access, adds new Start page features and personal Start pages, support for a new MSG-3 module, and the ability to create a Windchill QMS change request, CAPA request, or Problem report from a problem in the FRACAS module.

2010

Relex 2011 is released. In addition to introducing the FIDES 2009 reliability prediction calculation model, it unveils the Accelerated Life Testing (ALT) module and a completely revamped version of iRelex, the web application for performing FMEA and FRACAS activities. It also supplies FMEA control plans and DVPs (design verification plans), supports multilanguage installation, and integrates with Windchill PDMLink and MPMLink.

2009

PTC (Parametric Technologies Corporation) acquires Relex Software Corporation a few months prior to the release of Relex 2009. Included in this release are the redesign of the Weibull module and the integration of the RBD and OpSim modules into one new module, named Relex OpSim. Also added are Assembly Library files, the FIDES 2004 reliability prediction calculation model, and support for printing to Microsoft Office 2007 Word and Excel files. For multiple-module licenses, Relex Architect and Relex iArchitect are renamed to Relex and iRelex respectively.

2008

Relex Reliability Studio 2008 is released. In addition to providing significant performance enhancements, it includes text calculations, FRACAS Lookup Table files, a Build FMEA from FRACAS function, the integration of the Siemens SN 29500 v1 and Chinese GJB/z 299C prediction methodologies, support of Oracle 11g, XML imports and exports, and a new Microsoft Active Directory interface.

2007

Relex Reliability Studio 2007 is released. It unveils many new features, including ease-of-use enhancements such as simplified interface and Project setup capabilities, a new graphing package, integration of the 217 Plus and Telcordia Issue 2 prediction methodologies, a new Enterprise FMEA tool, and a new Relex iArchitect interface that also incorporates dashboards.

2006

Relex Reliability Studio 2006, a comprehensive, integrated tool set, is released, providing solutions throughout the enterprise and defining the next generation of reliability engineering.

2005

A wide array of consulting services are added, including Design for Reliability, Design for Maintainability, Risk Analysis, Field Data Tracking, and Reliability and Maintainability Planning.

2004

With the release of Relex 7.7, mission phase support is added to Relex RBD, and many major enhancements are added to other modules. Additionally, with the release of Relex FRACAS 2.2, Relex Dashboard is introduced.

2003

Relex OpSim (Optimization and Simulation) is introduced, and the Enterprise Edition of Relex FRACAS is unveiled.

2002

Relex Markov and Relex FRACAS are introduced. Additionally, support for the 299B Chinese reliability prediction calculation model is added.

2001

Relex Weibull, a powerful tool for life data analysis, becomes a part of the Relex Reliability Software Suite in the Relex 7.3 release.

2000

Relex Event Tree is released and support is added for two new reliability prediction calculation models: CNET 93, HRD5, and PRISM.

1999

Relex 7.0 is rolled out, launching Relex Fault Tree and providing users of other modules with new features and major enhancements.

1998

1993

The Relex product line is redeveloped for Windows 3.1. This release solidifies its reputation as a leader in the development of reliability software packages.

1987

Relex 217, a DOS-based reliability prediction package based on MIL-HDBK-217, is the first product to be released. The name Relex is derived from the term Reliability Excellence. The popularity of this product leads to the development of Relex Bellcore, Relex FMEA/FMECA, and Relex Maintainability Prediction over the next several years. Relex 217 and Bellcore eventually evolve into Relex Reliability Prediction, with separate licenses available for supported calculation models.

1986

Innovative Software Designs is incorporated to pursue its goal of producing a set of superior, user-friendly reliability analysis software tools by combining expertise in reliability analysis with expertise in software engineering.
