The best-selling fault
tree analysis package. FaultTree+ provides a visual fault tree builder
and a comprehensive analysis capabilities. FaultTree+ also includes
an event tree analysis option. Powerful reporting, charting and import/export
facilities are included.
A sophisticated
Monte Carlo simulation package for analysing systems availability
and reliability problems using fault trees or reliability block diagrams.
The AvSim+ Monte Carlo simulator engine is the result of 8 years development
during the evolution of the AvSim+ product. The simulator enables
AvSim+ to model complex redundancies, common failures, ageing and
component dependencies which cannot be modelled using standard analytical
techniques.
An integrated visual
environment in which failure rate prediction, FMECA, Reliability Block
Diagram, Fault Tree, Event Tree and Markov analysis are combined.
Failure rate predictions are calculated from the Bellcore standard
for electronic parts, the MIL-HDBK-217 standard for electronic equipment,
the RDF 2000 standard for electronic equipment and the NSWC-98/LE1
Handbook for mechanical parts.
Reliability Centred Maintenance
is a technique that focuses on the optimisation of maintenance procedures
with respect to cost, safety or environmental goals. RCMCost provides
a visual environment in which to identify important maintenance actions
through a FMECA. A simulation facility can calculate the effects of
ageing, crew mantime costs and the costs of spares and outages in
relation to preventive maintenance and inspection intervals.
One of the commonly used
techniques in the preliminary phase of a safety study is a hazard
and operability study. HazopPlus provides a familiar visual
environment in which to design and use the study and action forms
that are the basis for entering Hazop information. Extensive reporting
facilities are available.
Life cycle cost analysis
is used to evaluate the through life cost of a system. lccWare allows
the user to define the cost elements during the system lifetime, starting
at the conception stage and continuing through research & development,
design, operations and maintenance and ending with system disposal.
Some reliability problems
can be solved effectively using the Markov analysis technique. This
method analyses state transition diagrams. Steady state or time dependent
transition rates are allowed. The time dimension can be divided into
phases that could represent different operating modes such as maintenance
tasks or varying loads.
The analysis of failure
or repair data can be achieved in a visual environment using the WeibullPro
software. The data can be fitted to various failure or repair distributions
and displayed in graphical form.
RiskVu provides a high
level interface for probabilistic safety assessment studies for those
users who are not familiar with the details of the underlying methods..
RiskVu uses the data from a FaultTree+ study and presents it in the
form of a failure event hierarchy. The user can modify some aspects
of the model such as failure rates or equipment outages. The quantitative
analysis is then repeated and the results displayed in report or graphical
form.
The Failure Reporting
Analysis and Corrective Action System (FRACAS) can be used to collect,
record and analyse system failures. The failures are reviewed and
corrective actions identified and verified. This powerful process
can be used to greatly improve the through-life reliability of the
target system.
The Network Availability
Program (NAP) enables users to predict the availability and reliability
of communication networks. The NAP network availability model utilises
an extended Reliability Block Diagram (RBD) methodology that addresses
the specific characteristics of network elements and their connections.
In addition to predicting network availability, NAP also provides
criticality rankings that identify weak spots in the network. NAP
provides many time-saving features to allow users to quickly construct
the network diagram. These include a parts library facility that allows
users to import their parts data in convenient groupings, a network
element library facility that allows users to construct common network
element diagrams and a fully interactive network diagram construction
facility.
Attack trees allow
threats against system security to be modelled concisely in an easy
to understand graphical format. The effectiveness of internet security,
network security, banking system security, installation and personnel
security may all be modelled using attack trees. With the increased
risk of terrorist attacks on homeland security, hacking attacks on
computer systems and computer-based fraud on banking systems, AttackTree+
analysis is an invaluable tool to system designers and security personnel.
AttackTree+ analysis provides a method to model the threats against
a system in a graphical easy-to-understand manner. If we understand
the ways in which a system can be attacked, we can develop countermeasures
to prevent those attacks achieving their goal.
IsoLib has been
developed to be used in conjunction with Isograph's existing range
of powerful analytical tools. Developed around the same rapid SQL
Server database are two distinct products - IsoLib
Parts Libraries and IsoLib
Project Management. The IsoLib Parts Libraries contain many thousands
of modern electronic and non-electronic parts and provides a comprehensive
source of failure data for users of Isograph’s reliability products.
The IsoLib Project Management program controls access to Isograph
software project files, using a checkin/checkout methodology, preventing
multiple users from working on an individual project at the same time.
An audit log is maintained so that details of who created, modified
and deleted a project can be determined.
The Report Generator
is a common component that is used in the majority of Isograph’s
RAMS products. It is very useful for the user to have a standard method
of designing, printing and exporting reports in each product. The
knowledge gained with one product can be applied to other products
without having to re-learn the process.
