This module allows you to analyze testing data from a small sample of overstressed products to predict the reliability of the product at normal stress levels. Typically used to analyze highly reliable products, this tool provides for identifying and resolving component weaknesses early in the design process. By applying environmental stresses above what the product is likely to experience in the field, you can obtain accurate reliability estimates in shorter time frames. In addition to analyzing ALT (accelerated life testing) data, this module provides general statistic, test planning, and summary calculators. For more information, see Windchill ALT.

This module allows you to quickly construct event trees and then calculate consequence, frequency, unreliability, and more. You receive it for free when you license the FTA module. For more information, see Windchill Event Tree.

This module allows you to quickly perform a FMEA (failure mode and effects analysis) or a FMECA (failure mode, effects, and criticality analysis) using either industry standards or standards that you define. This tool includes vast failure mode libraries for electronic and mechanical parts and provides a wizard to help you set up and configure a System file for FMEA analysis. For more information, see Windchill FMEA.

This module allows you to document and track any type of incident (such as failure, repair, and customer complaint) so that an effective corrective action is identified, implemented, and verified as quickly as possible, thereby avoiding a negative impact on cost, schedule, safety-related events, customer lack of satisfaction, and more from recurring incidents. You can apply the information gathered from the FRACAS to future system designs to help ensure better reliability as product development moves forward. For more information, see Windchill FRACAS.

This module allows you to quickly construct fault trees to find potential problems using a systematic top-down approach known as FTA (fault tree analysis). In addition to providing a wide range of gate types and event types, this tool supports common cause failures and repeated events. When you license it, you also receive the Event Tree module, which is described earlier in this table. For more information, see Windchill FTA.

This module allows you to calculate the cost of a product over its entire lifetime. The user interface provides a CBS (cost breakdown structure) that you can customize. This tool also enables you to define design alternatives and time-dependent variables. The synchronized Equation Editor provides a host of mathematical tools and access to all variables. You can perform parametric analogy, bottom-up and direct cost analyses, and NPV (net present value) and sensitivity analyses. For more information, see Windchill LCC.

This module allows you to analyze dozens of maintenance and repair parameters, including MTTR (mean time to repair). It incorporates industry-accepted maintainability standards, and it enables you to define simple repair tasks, FD&I (fault detection and isolation) outputs, and more. For more information, see Windchill Maintainability.

This module allows you to create Markov state transition diagrams to analyze complex and sequence-dependent systems. It includes both a fully featured graphical user interface for creating Markov diagrams and a powerful Markov calculation engine. Markov models are useful for finding the behavior of a system when there are common cause failures, imperfect coverage, complex repair policies, degradation, shock effects, induced failures, dependent failures, and other sequence-dependent events. For more information, see Windchill Markov.

This module allows you to evaluate the failure rate and MTBF of your system or product. It supports running reliability allocation calculations and performing derating analyses to pinpoint areas for potential reliability improvements. In addition to supporting all widely accepted reliability prediction calculation models, it allows you to access comprehensive libraries that contains data for hundreds of thousands of parts. For more information, see Windchill Prediction.

This module allows you to quickly simulate and optimize complex redundant systems to evaluate reliability, availability, and MTBF (mean time between failures). This fully featured graphical evaluator enables you to create an RBD (reliability block diagram) by inserting and connecting blocks representing system elements and then running fast and accurate reliability calculations using the built-in Monte Carlo simulation engine. It also allows you to incorporate maintenance activities, including the management of spare parts and repair resources for critical components, to determine how these activities influence key reliability parameters. Based on a goal of achieving minimal costs, maximum reliability, or maximum capacity, this tool can optimize maintenance intervals, repair resources, and spares to provide the most efficient and cost-effective use of your maintenance resources. It also supports phase diagrams so that you can model the operation of subsystems and components in specific mission phases of a phase-based system. For more information, see Windchill RBD.

This module allows you to analyze failure data trends using Weibull and other failure data distributions. It determines the best distribution to use when analyzing data sets and generates colorful plots of analysis results, even supporting the display of multiple plots on the same graph. In addition to analyzing parametric, non-parametric, and reliability growth data analysis, this tool provides general statistic, test planning, and summary calculators. For more information, see Windchill Weibull.
