Integration with Product Development Process and Other Reliability Tools
Support for Large Multi-Level System Configurations (Including FRACAS Integration)
Xfmea’s flexible System Hierarchy interface allows you to manage large, multi-level system configurations with as many levels as you need and any number of items per level. You can fully define the properties for each item (e.g., supplier, part number, reliability characteristics) and you can perform FMEA and related analyses at any level within the configuration.
To save time and ensure consistency, you can automatically import system configuration data from an external Bill of Materials file or from ReliaSoft's XFRACAS web-based failure reporting and incident tracking system. For an enterprise database, you can maintain a direct link to the XFRACAS system, which makes it easy to resynchronize at any time. This FRACAS connection also enables the FMEA team to tap into valuable information about failure modes that are observed during testing and in the field, including incident quantities and new failure modes that may not have been considered yet.
Change Point Analysis or Preliminary Risk Assessment
The Risk Discovery Analysis feature provides a choice of two configurable methods for the preliminary analysis that will help you choose which items should receive more detailed consideration via FMEA (e.g., a change point analysis or preliminary risk assessment). The first option allows you to answer a series of yes/no questions and the second option allows you to assign ratings for a variety of different factors and then calculate an overall criticality value for each item.
Failure Modes and Reliability Analysis (FMRA)
You can use the new failure modes and reliability analysis (FMRA) feature to integrate statistical reliability analysis calculations into your FMEA activities. Specifically, this view can be used to:
- Display all of the FMEA records that could have an impact on system reliability in a single hierarchical tree, and use this view to define the relevant reliability characteristics.
- Calculate the probabilities of failure required for a quantitative criticality analysis.
- Use the occurrence ratings that have been defined in the FMEA to generate a preliminary baseline reliability estimate for the system that can be improved later when actual failure data become available.
- Synchronize with BlockSim’s reliability block diagrams (RBDs) or fault trees, which facilitate more realistic system modeling (e.g., by considering redundancy, common cause failures, etc.).
- Now in Version 10, you can use the FMRA to allocate the target reliability and target availability. You can also push the calculated reliability/availability to metrics that allow you to display the information in other locations and also track how the value has changed over time.
The analysis plan utility allows you to keep track of team members, ground rules, estimated completion dates, scheduled work sessions and other details that will help you to plan and manage your analysis projects. The software makes it easy to generate a high-level overview of all pending analysis projects and also to generate a report for each individual project plan.
