2. ASENT Overview
ASENT’s R&M toolkit has been specifically designed to address the demanding needs of today’s Reliability and Maintainability engineering environment. It’s unique client/server architecture delivers more database horsepower than other tools on the market, and provides a superior environment for teaming and collaboration.
ASENT includes a wide range of R&M capabilities, many time saving features, and in conjunction with EAGLE, automates the exchange of data between Reliability, Maintainability, and Logistics.

3. ASENT Overview
This slide shows the tools that make up our world class family of software products: ASENT, EAGLE, EAGLE Publishing System, and EAGLE MMIS. This diagram shows the interaction between each of these tools. For example, ASENT has a bi-directional interface to EAGLE.

Spares
Modeling
Requirements flow down from systems engineering, and these consist of harware, mechanical, and software design requirements.
ASENT deals mainly with the area inside the box. Part lists and design information can be automatically imported from the CAD tools. Engineers can use ASENT to build the product tree structure, and start performing design trade-offs.
Data is entered once and reused many times to perform a wide range of upfront design analysis.
RBD Analysis, along with Reliability Predictions can be performed. This data is then readily available for FMEA/FMECA, Maintainability Predictions, Testability Analysis, Safety, and RCM Analysis.
ASENT includes a time-saving LMI data interface that allows you to quickly and easily populate your LMI database with design analysis information.

5. Concurrent Use of Project Data
Presentation Title
November 16, 2018
Concurrent Use of Project Data
Concurrent use of project data
Data visible to multiple users/engineering disciplines
Powerful search capabilities
Quick and easy to locate useful data
Here, we have a diagram that represents concurrent use of data. Notice that different engineering disciplines are listed below each computer to represent the types of users that may be working together. For example, there may be one or more reliability engineers that could be involved in defining the product tree structure, reliability predictions, modeling, and FMECA work. Maintainability engineers could leverage off of the product tree structure and the failure rates when looking at different maintenance philosophies. Testability engineers could leverage off the FMECA to start looking at test coverage issues. This information would be readily available to Logistics and they could even begin creating the LCN structure in ASENT. At any time all or part of this information could be captured and transferred to EAGLE.
In order to have concurrent access of project data make sure that the tools that you select truly support this process. Your tools must support multiple users, simultaneously accessing data from geographically dispersed locations. Desktop tools are typically not adequate for this, and even tools that run over a network may not be adequate. ASENT and EAGLE both have client/server architectures and are more than capable of accomplishing this.

6. Concurrent Use of Project Data
Presentation Title
November 16, 2018
Concurrent Use of Project Data
ASENT performs early/upfront design analysis
Project data is visible to other users
Less likely to reinvent the wheel
Save time by conducting analysis in parallel
Allows rapid design iteration - design impacting
Design, build, maintain anywhere
Let’s look at some of the benefits of multiple users being able to use the data concurrently. First, the project data is visible to the entire team. This improves communication and members of the team are less likely to waste time reinventing the wheel. Also, this allows many of the analyses and tasks to be completed in parallel so that more trade-offs and analysis can be performed during the allotted time. This facilitates rapid iterations of the design so that the up-front design analysis can impact the design early on, where it saves your company the most money. Since users can be geographically dispersed it also supports the concept of being able to design, build, and maintain anywhere.

Handles Project Administration:
Add, Copy, Delete projects
Archive/Restore project data
Add, Modify project settings
Assign Users to projects
Invoke other ASENT modules
Bidirectional LSAR Interface
This slide just lists some of the capabilities included in ASENT’s Session Manager. This is the first module that a user sees when they invoke ASENT. In ASENT we organize the data by project, but that project can represent a board, a box or an entire system.
From the Session Manager, the user can invoke the other ASENT modules:
Reliability Manager, FMECA Manager, Maintainability Manger, and the Part Library editor. The Board Manager, where Thermal Analysis is performed, is invoked from the Reliability Manager.
The user can also invoke the LSAR Interface from the Session Manager in order to pass data between ASENT and EAGLE or any other tool that supports a B format(SLIC, OMEGA).

ASENT – Graphics & Supporting Documentation
Extensive use of graphics. Manage supporting data (Excel, Word, PDF, Video)
Graphics are used extensively in ASENT and throughout all of the modules. This slide shows a few examples. Thermal results, schematics and board placement, pictures of the equipment, video, correspondence and much more can be stored along with the rest of your project data.
This can be particularly useful if you come back to a prediction several years later to refresh your memory. Often, just a part list won’t provide you with all of the information that might need.

Tracks Failure Categories
Powerful Completeness Checker
Preliminary Safety Hazard Analysis
Testability Analysis
RCM Analysis using ATA MSG-3, ASD S4000M, NAVAIR ,MIL-STD-2173(AS), Def Stan Part 3
The FMECA Manager leverages off of the product tree structure and failure rates calculated in the Reliability Manager. It supports a Mil-Std-1629A FMEA/FMECA. Hardware, functional, or combination FMECAs are supported by ASENT. Libraries are used extensively by the tool so data can be entered once and reused many times. A powerful completeness checker helps you to quickly assess your FMECA status and identify any missing information.
The Testability portion of the FMECA tool allows the user to leverage FMECA data and enter detection/isolation information for selected failure modes. Detection/Isolation groups are defined(i.e. VISUAL, PBIT, IBIT, SRA Testpoints, etc...) along with test codes in the Library Manager. The tool will calculate fault detection and fault isolation and generate reports that quickly verify whether the current test coverage is sufficient to meet requirements.
The RCM analysis portion of the FMECA tool allows the user to leverage FMECA data, and automates the analysis process laid out in Mil-Std-2173(AS), MSG-3, and NAVAIR The built-in logic trees guide the user through a series of questions to determine whether an item is a Structurally Significant Item(SSI), Functionally Significant Item(FSI), or a Non-Critical Item(NCI). Based on the user responses, a preventive maintenance analysis is done to determine if there is some type of task that will reduce or prevent the consequences of a failure.
