What’s New
in ASENT 12.5?
Version 12.5 of the ASENT R&M Toolkit was just
released. ASENT is an integral part of our family
of world-class products, and we continually strive
to make it better with each release. Input from
training classes, customers, and work done on Six
Sigma productivity projects, have all contributed
to the latest version of ASENT.
This page
will briefly describe some of the new features
included in the ASENT 12.5 release. With each
release there are many minor enhancements that
help fine tune the help files, layout of menus,
user interfaces, and other aspects of the toolkit.
Here, we will focus on a few of the more notable
changes.
FMECA
Manager – The FMECA toolkit has been the focus
of a wide number of enhancements. New features
make it much easier to perform Testability
Analysis, and report the results. The Failure Mode
Criticality Matrix has been expanded to include an
additional page that lists criticality values for
each failure mode and a summary of their values.
The Logan FTA interface is much more robust, and
now allows users to leverage ASENT’s FMECA data to
create multiple, complex Fault Trees in a single
operation. A new set of reports have been added to
allow users to document their Reliability Centered
Maintenance (RCM) Analysis. These reports offer a
full suite of options and allow you to specify
which assemblies are included in the report by
assembly type.
Reliability Manager – The Mission Profiler has
been expanded to allow you to include both
Operational and Non-operational mission phases in
a single profile. A menu item has been added to
the subassembly menu, allowing users to import
part lists for subassemblies in addition to
boards. It has always been easy to import trees or
sub-trees from existing ASENT projects, but now
you have the ability to import trees or sub-trees
from an Excel file. You can either add to the
existing product tree or replace portions of the
tree with this new feature. A new Reliability Tree
Report has been added to complement the existing
failure rate prediction reports. It provides a
highly tailorable Excel output with much more
available information. Users have always had a
great deal of flexibility when it comes to thermal
data. Data can either be directly entered, or
associated with an existing part list by using an
Excel file, or calculated by performing a thermal
analysis within ASENT. In addition, the user can
now quickly approximate junction temperature rises
based on power dissipation and junction-to-case
thermal resistance. This new feature provides a
quick solution for situations where thermal
analysis data is not available.
Component
Data Manager – Currently, users can bulk load
part library data from Excel files for a variety
of part types. In ASENT 12.5 we have expanded this
capability to allow you to import miscellaneous
parts and inductors.
LSAR
Interface Tool – ASENT continues to provide
the most robust capability for interfacing to LSAR
tools. While many tools advertise some ability to
pass LSAR data, only ASENT provides a
full-featured import/export capability that is
quick and easy to use. Many new features have been
added in this release. The focus of these
enhancements has been to continue to make the
interface more robust to handle wide variations in
data, and to provide users with greater options
and flexibility in controlling the flow of data
either into or out of ASENT.
Relex
Translator – This tool makes it very easy for
customers to transition from Relex to ASENT.
Legacy data files can be quickly translated to
create new ASENT projects. New options allow you
to build a consolidated library of parts created
through the translation of many legacy projects.
|
|
Interconnected
ASENT
supports collaboration through an extensive set of interfaces
to software toolkits for other disciplines. Examples include
the SLATE ®and DOORS ®systems engineering tools, interfaces
to all major CAD packages, and the
EAGLE
® SLIC ®and OMEGA ®logistics tools. ASENT's interfaces provide
automated data flow between tools to improve communication
and productivity in a highly dynamic design environment.
This enables analyses to be performed in parallel, significantly
reducing design cycle time.
With
ASENT, the emphasis is on data sharing across tools to provide
a significant productivity lift. It interfaces with
LOGAN Fault & Event
Tree Analysis Tool,
RAC's
PRISM ®and
RAPTOR tools
for reliability analysis. ASENT also interfaces with Giordano's
Diagnostician, enabling automated database population to
significantly reduce the need for user-entered data. ASENT's
reporting and interface capabilities make the results from
these tools readily available to other engineering disciplines.
A product tree can be imported from an existing LSAR and
easily passed to PRISM to perform a reliability prediction.
These results are then available in ASENT's FMECA and Maintainability
tools.
In
addition, ASENT works with Raytheon's
EAGLE
and AIMSS
software products to provide a suite of tools that perform
product supportability analysis and documentation throughout
a product's lifespan.
Information Reuse
While
other tools support data reuse by allowing the user to copy
an existing project file, quickly finding the right file
can often be a problem, especially when the data owner is
not available: in a meeting, on vacation or a business trip,
etc. ASENT, in its network configuration, solves that problem.
ASENT can leverage a company's network to quickly connect
with other ASENT servers anywhere in the world. Once connected,
wildcard searches can easily be performed in parallel across
all projects on a server - a decided advantage over the "hit
or miss" serial searches provided by other tools. The
customer can download the data of interest and incorporate
it into a project or product.

Through
its extensive set of interfaces to other tools, ASENT allows
access to legacy data from separate databases, such as LSARs,
to rapidly build the basis for Reliability, FMECA, Maintainability
and Testability analyses and manage the data within ASENT
as shared data. Unlike other tools, ASENT does not burden
the network, allowing Microsoft's ®powerful SQL Server ®engine
to perform all the data intensive manipulation on the server,
returning only the results.
It is estimated that up to 70% of the analysis effort is
devoted to data acquisition and re entering data into analysis
tools. ASENT's wide range of interfaces coupled with its
ability to provide an enterprise solution significantly
reduces the effort required to perform these tasks.
Reliability Manager (Failure Rate Predictions and Reliability Block
Diagrams)
ASENT’s Reliability Manager – the cornerstone of the entire
toolkit – contains some key usability features: a powerful
product tree editor, the ability to import almost any file
format, quick access to part data, prediction tools for both
operating and non-operating failure rates, sensitivity
analysis, a mission profiler, comprehensive reporting
features, and a powerful replicate function. This replicate
feature alone can save an enormous amount of time when
updating designs with many common modules.

ASENT includes many of the
most popular prediction methods used for calculating both
operating and non-operating failure rates. Other companies
charge extra for these methods, but they are all standard
with ASENT.
When performing
calculations, failure rate status flags are clearly displayed
next to each item in your product tree structure. When failure
rates have been calculated, these flags alert the user to any
potential problems.

ASENT’s bi-directional
interface to the SRC's PRISM tool provides several advantages:
• ASENT’s product
tree structure and powerful editing capabilities, along with
its extensive part library, are readily available to PRISM.
•
ASENT’s comprehensive reporting
capabilities can be used in addition to the reporting found in
PRISM.
• By using RAC’s tool
to calculate failure rates, users are assured that the latest
models associated with the PRISM prediction method are used.
•
These failure rates are
readily available to ASENT users for follow-on analyses, such
as FMECA or maintainability predictions.
•
PRISM is invoked from ASENT
by simply selecting a menu option.
A similar interface is currently planned for RIAC's new
217Plus tool.
Reliability Block Diagram
(RBD) Analysis

ASENT’s RBD Analysis tool allows
you to model a system, using either the Mission Reliability
approach or the Reliability with Repair approach to
determine system reliability, either in terms of probability
of mission success or in terms of Mean Time Between Critical
Failure (MTBCF) and Mean Time To Restore Functionality (MTTRF).
You can perform sensitivity
studies as functions of time, discrete events (firings,
launches, etc.), system architecture, item reliability or item
maintainability. The tool supports elements modeled in
series, parallel, series-parallel combinations, and complex
active or standby redundancies. Tradeoffs can be quickly
performed to identify a system’s critical functions and
reliability choke points as well as determining logistic
factors, such as Available Preventive Maintenance Time, System
Availability, Logistics (Serial) Reliability.

As the
Reliability Product Tree is updated, the RBD
Analysis is automatically updated and is
easily visible from the product tree! A
suite of utilities is provided to maximize
your productivity including a completeness
checker, a utility to initially populate, or
quickly change the data of all the RBD
blocks. The Reliability Modeling Worksheet
provides a convenient means to quickly
tailor or update your model.
The RBD Analysis Report presents
your analysis, with block diagrams and supporting tables in
Excel format. Armed with this information, you have an early
opportunity to improve your system design.
FMECA
Manager
( FMECA, RCM, and Testability Analysis )

ASENT offers the most robust FMECA capability on the market
today. With true relational integrity between causes,
failure modes, and next effects, you can be assured of the
accuracy of your analysis results. You can specify multiple
next effects and end effects for each failure mode. The
built-in library of part types, along with failure modes and
failure mode distributions, greatly reduces the time
involved during piece-part level FMECA.
ASENT’s FMECA tools
support functional, hardware, or combined FMECAs. With the
unique ability to specify a function and then link the
function to a group of board parts, ASENT allows you to
effectively model depot-level isolation and repair
activities.
ASENT lets you perform
top-down or bottom-up FMECAs, and gives you the flexibility to
enter data as it becomes available rather than in a forced
order. Assemblies, parts, and signals can be modeled along
with the related failure modes and effects. The relationship
between failure modes, effects, and the tree structure are
tracked automatically so that updates are easy to make at any
time. After the updates have been completed, failure mode
ratios and criticality numbers can be recalculated and new
reports generated with the simple tap of a key.

Often, the tree structure
used in performing a FMECA differs from the hardware tree used
for a reliability prediction. Because of this, ASENT provides
full tree editing capability in the FMECA Manager. The
reliability tree can be used to whatever extent desired, but
you have the flexibility to deviate from it when needed.
Since the FMECA process can
be a considerable documentation effort, ASENT’s powerful
Completeness Checker helps to assess your FMECA status at a
moment’s notice and identify any missing data – another great
time saver!

|
RCM Analysis
ASENT's
Reliability Centered Maintenance (RCM) tool is fully
integrated into the FMECA, giving you a head start in your
analysis, as much of the critical data is already defined.
This integrated approach also simplifies future updates and
maintenance for subsequent deliveries, as changes in the
product structure, failure rates, failure modes, effects and
criticalities automatically flow into the RCM analysis!
You can
conduct analysis using the methodologies of Mil-Std-2173, and
UK MoD MSG-3, or NAVAIR 00-25-403. The questionnaire logic is
fully automated for these methods and includes a full task
analysis suite to allow you to define the types of RCM tasks
for each failure mode. The task analysis suite provides you
with extensive capabilities to add explanatory notes to any
and all tasks as well as full control over the order of the
presentation of the tasks.
Often,
the RCM results for one failure mode will be applicable to
others. ASENT provides you a capability to quickly copy the
RCM results, and RCM tasks, to one or more failure modes.
A full set of report formats are provided
for each RCM method, in Excel format, for easy inclusion into
customer deliverables.
The RCM results are also part of the LSAR export, providing
extensive documentation in the BG table of the RCM analysis.

Testability Analysis
The
testability tab of the FMECA Manager allows
you to make use of the FMECA product tree
structure and data, and provides a means to
enter fault detection/isolation and false
alarm rate information for failure modes.
You can easily build the isolation list from
a dropdown list of items that are applicable
for each ambiguity group, and order them by
failure rate or other criteria. Normally,
this information is entered only at the
lowest level of the product tree structure,
and all intermediate values are calculated
by ASENT.
ASENT’s powerful Library Editor allows you
to define detection/ isolation groups (IBIT,
PBIT, visual, test points, etc.) and
populate the test code library. Test codes
can be organized into categories (hardware,
software, etc.) for easy reference, and
default false alarm rates can be specified
for each test code. ASENT will quickly
calculate fault detection/ fault isolation
percentages, and false alarm rates for each
group. You can easily see how test coverage
stacks up in comparison to your design or
customer requirements.

This screen
shows how you might set up detection/isolation groups. Here,
various flavors of BIT are listed along with a VISUAL group
and test points for both WRAs and SRAs.
Also you can
define Isolation Group Sizes. For example, group 6 represents
test points on the SRA. This example shows groups that isolate
to 4 or fewer components, 8 or fewer components, or 10 or
fewer components. Below shows a Test Coverage Summary report.
You can turn on or off a wide variety of options when
generating testability reports, so that only information that
interests you is output.

ASENT’s
testability completeness checker will identify any missing or
incomplete data. This saves time and effort, and provides
extra assurance that the results are accurate and complete.
You will appreciate the wide range of available reports.
Whether you need a quick summary of test coverage for a
certain group, or a detailed report that slices the data a
certain way, ASENT has it covered. ASENT allows you to copy
testability data from one failure mode to one or more failure
modes with only a few mouse clicks. This can save considerable
time when performing analysis on areas of your design with
similar detection/isolation criteria. Alternate tests can be
defined in order to perform trade studies.

ASENT’s
Testability Analysis capability is an integral part of its R&M
tool suite. The product tree structure and failure rates are
readily available, along with FMEA/FMECA data. Whether it is
your Testability Group or your Maintainability Group that is
interested in analyzing your design’s test coverage, they will
enjoy the benefits of ASENT’s integrated solution. Its
client/server architecture supplies additional benefits by
providing concurrent access to project data for a wide range
of engineering disciplines. This reduces cycle time by
allowing many of the analyses to be performed in parallel.
Maintainability Manager

|
The ASENT Maintainability toolkit
has been optimized to reduce data entry and
maximize the use of existing reliability data to
help you efficiently manage the maintainability
analysis process. All necessary tools are included
to assist in your analysis. The product tree
structure and reliability prediction data is
readily available in ASENT’s Maintainability
toolkit, but you can quickly and easily add covers
or other hardware often excluded from reliability
predictions.
Both Corrective
and Preventive Maintenance analyses are supported.
ASENT calculates maintenance times (both mean and
maximum, e.g., MTTR and MMaxCT) and outputs the
result in both minutes and hours.
Organizational,
intermediate, and depot levels of repair are fully
supported for procedures II and V of MIL-HDBK-472.
The tool’s powerful “what-if” mode instantly
models the impact of various design and
maintenance tradeoffs in real time.
ASENT’s built-in
task libraries (MIL-HDBK-472 and RADC-TR-84-165)
greatly reduce the time spent entering data. Also,
since replacement tasks are often the same as
remove tasks, only listed in reverse order, ASENT
allows you to enter these with a single click of
the mouse.
|

Click image to enlarge |
The tasks are
then automatically entered and the appropriate
task times are pulled from ASENT’s built-in task
time libraries. When you combine this information
with customizable Task Libraries, and the ability
to enter Judgments as difficulty factors for
working in hard-to-reach or adverse conditions,
you get a powerful combination of maintenance
planning tools.
Inherent,
achieved, and operational availability are
calculated as part of the analysis and are
prominently displayed, along with other analysis
results on the prediction results screen. With
ASENT, the analysis results are consolidated on
one easy-to-read page, so the affect on your
system can be quickly determined.
The
Maintainability tool comes with an extensive suite
of reports. ASENT’s comprehensive reporting allows
you to quickly slice the data, so that you can
view just the information you want. The convenient
Excel format makes it particularly easy to
incorporate outputs into customer deliverables.
Prediction results at a glance, built-in task time
libraries and images, a familiar spreadsheet
interface, the flexibility to add judgments and
difficulty factors, and extensive modeling
capabilities all help put ASENT’s Maintainability
Toolkit into a class by itself. |

Board
Manager - Thermal Analysis
ASENT’s Thermal Analysis tool leverages
pioneering work in the
physics of failure based analysis.
This tool can help you proactively affect
your board design by performing trade
studies based on component placement, power
dissipation, packaging, mounting technology,
board composition, and cooling design. Five
different cooling methods are available.
You can quickly identify
or validate thermal-related problems, and identify and
quantify potential solutions. The graphical analysis display
lets you see the results, graphically showing vital
information such as failure rate, stress, power consumption,
and temperature (i.e., case, junction, layer, and
substrate).
A powerful editing feature
comes standard with this tool, which allows you to quickly
change the board outline, composition, or component placement.
When defining the board composition, you can create special
regions of material or cutouts on board layers. Fully
definable plated-thru holes, vias, and fin structures may also
be added to assist with selected cooling methods.
Thermal results are used by the
reliability prediction when calculating failure rates,
thereby improving the accuracy of the prediction model. |
