R&M Engineering

The purpose of the Reliability and Maintainability (R&M) Engineering Community of Practice (CoP) is to help the R&M workforce plan and execute a comprehensive R&M program using an appropriate strategy consisting of engineering activities, products, and digital artifacts. This community encourages collaboration, provides links to DAU R&M Engineering courses, and hosts the R&M Engineering Management Body of Knowledge (BoK). Users of the BoK will find helpful links to other R&M resources that provide detailed "how to" examples and mathematical models needed to perform R&M engineering activities. The R&M Engineering Management BoK is an acquisition tool focused on the R&M Engineering activities needed to deliver reliable, maintainable, and supportable capabilities to the warfighter.

RelTools Dashboard 2.0 is now available!
View Announcement

Introducing version 2.0 of the RelTools Dashboard, the Shiny app that captures all of DAC’s reliability models. The app is now equipped with cutting-edge tools designed to elevate reliability data analysis and explore the impacts of AI on the reliability of Army systems. The new Data Visualization Tool allows users to uncover insights into failures with interactive plots that facilitate data interpretation. The recently developed AI reliability tools include a Wheel of AI Failure Modes, an interactive tool that identifies and describes the potential failure modes associated with AI, as well as an AI Reliability Scorecard to evaluate the activities for an AI program and identify reliability mission risks and areas for improvement. Individuals within the DoD who have government network access and a CAC can explore the enhanced capabilities of the RelTools Dashboard by going to https://apps.dse.futures.army.mil/RelToolsDashboard/.

QUESTION

​I am supporting a mid-tier acquisition program which is looking into developing FD&SC from the government perspective.  There needs to be the right amount of documented criteria (not too broad and not too shallow).  Does anyone have any examples of FD&SC used on programs and/or can provide assistance on how to ge this effort started?

Thanks,

Bob Beauregard

​This aligns well with several of the Product Lifecycle views we have socialized.  I do recommned one area for improvement.   Where "Sensor Design" is used, change it to something like Health Managment System (HMS) Design.  Sensor can be easily limited to sensor produced data as opposed to systme product produced data for HM.

Would be great to show where AI and ML could be used for data fusion between maintenance data and sensor data.​

Attend the June 1 Digital Engineering in Reliability & Maintainability Webinar
View Announcement

Attend the webinar here: DE in R&M Webinar

With Digital Engineering (DE) becoming a critical component of engineering practices, R&M engineers need to be ready to understand and integrate DE into their daily activities. Reliability and Maintainability (R&M) engineering activities should be properly integrated across all functional areas of a program to implement an effective R&M engineering program. Digital Engineering provides a common platform for this sharing of information and data across the lifecycle. DoDI 5000.88 calls for digital representations of the system as being an integral part of system design. In addition, DoDI 5000.91 includes supportability in the digital authoritative source of truth. To implement these policies, new techniques are in development for the R&M discipline which include current efforts to create a Model Based Failure Modes and Effects Analysis (FMECA) Data Item Description. The integration of DE into R&M practices also needs to be communicated to the workforce so that they are ready to support R&M in programs. The five R&M courses (ENG0850 through ENG0890) have been reviewed and are in the process of being updated to include the instantiation of digital engineering into R&M engineering activities. ENG0900 "R&M Engineering Interface with Product Support" planned for deployment by DAU by FY23Q4 includes three lessons focused on digital engineering and digital product support. Finally, this webinar will summarize the key tenets of DE and highlight applicability across the acquisition lifecycle.

Integrating R&M Throughout the Digital Engineering Ecosystem

The Reliability and Maintainability Symposium (RAMS) attracts leading Reliability and Maintainability experts from across industry, academia, and the U.S. Government. This has been an annual event since the 1950s alternating between east and west coast areas of the US. RAMS generates peer reviewed technical papers that are published in the IEEE Xplore each year (paper presentations NOT released by RAMS, only from authors). The topics are based from RAMS fields of study (approximately 35 topic areas). Many Doctoral Candidates use this symposium for their PhD pursuits. 

The DoD Government and Industry community participates in this forum each year through participation in the Board of Directors, Management Committees, presenting papers, and hosting an interactive session that features a panel of senior reliability experts representing the U.S. Department of Defense (DoD), NASA, and Industry. This "reverse panel" session is sponsored by the Director, Specialty Engineering from the Office of the Undersecretary of Defense for Research and Engineering within the U.S. DoD. Typically over 100 people attend this session and lively debate is encouraged.  

The 70th Annual Reliability & Maintainability Symposium (RAMS®) will be held at The Clyde Hotel in Albuquerque, New Mexico, USA during the week of January 22–25, 2024. 

The theme for RAMS® 2024 is “Integrating R&M Throughout The Digital Engineering Ecosystem”. With the ongoing shift to a digital engineering approach, a Digital Engineering Ecosystem enables stakeholders, whether from government, industry, and/or academia, to work collaboratively and securely within and through a digital environment using shared knowledge and resources across the lifecycle from concept to disposal. R&M engineering and data is one of the essential artifacts within the Digital Engineering Ecosystem to be shared with stakeholders for the data-driven acquisition, development, and operations. There is an urgent need to effectively and efficiently integrate R&M engineering and data utilizing all the techniques discussed in prior RAMS® including utilizing Artificial Intelligence and Machine Learning (AI/ML) with Big Data and digitally transforming data into model-based system engineering.

If you wish to present a paper, presentation or tutorial at RAMS® 2024, now is the time to begin your preparation. The paper must represent your original work and should not be published or presented in any other
journals or conferences. Presentations must be based on the conference theme and topic areas above. Tutorials must address broad areas of interest in reliability and maintainability engineering.
If interested submit your abstracts via rams.org and the abstract submission process open from March 1, 2023 until April 30, 2023.

Welcome

Welcome to the R&M Engineering Body of Knowledge (R&M Eng BoK)


The DoD R&M Engineering Management Body of Knowledge (R&M Eng BoK) provides a compilation of R&M engineering activities to be implemented during each major capability acquisition phase. These R&M activities are organized into four functional areas:

  • R&M Engineering Management

  • Systems Engineering

  • Test and Evaluation

  • Procurement

Click here to access the downloadable R&M Engineering Management Body of Knowledge (R&M Eng BoK) PDF document.

The activities within the R&M Engineering Management BoK are structured by major capability acquisition phases and are also relevant to other Adaptive Acquisition Framework (AAF) pathways to include Urgent Capability Acquisition, Middle Tier of Acquisition, and Software Acquisition. More information on the AAF pathways can be found at the Adaptive Acquisition Framework (AAF) Homepage.

The AAF meets the policies and principles that govern the operation of the defense acquisition system as stated by DoD Instruction 5000.02, Operation of the Adaptive Acquisition Framework. The AAF structure provides Program Management with the option to use a single pathway of a combination of pathways to achieve their objectives based on the capability being acquired.
