Availability Workbench
Availability Workbench is our flagship suite of availability simulation software. It includes the latest versions of Isograph's AvSim+ and RCMCost software for system availability simulation and reliability centered maintenance. In addition it includes Weibull Analysis and Life Cycle Costing modules.
Availability Workbench is used to optimize maintenance and spares policies, predict system availability and throughput and estimate life cycle costs. It includes well known modeling methods such as FMECA, Reliability Block Diagram Analysis and Fault Tree Analysis.

Reliability Workbench
An integrated visual environment in which failure rate and maintainability prediction, FMECA, Reliability Allocation, Reliability Block Diagram, Fault Tree, Event Tree and Markov analysis are combined.
Failure rate predictions are calculated from the Telecordia, MIL-HDBK-217, 217 Plus and IEC TR 62380 standards for electronic equipment and the NSWC-98/LE1 Handbook for mechanical parts.
FMECA, Reliability Block Diagram and Fault Tree analysis are performed to well-known standards such as MIL-STD 1629 and IEC 61508.
FaultTree+
The best-selling fault tree analysis package. FaultTree+ provides a visual fault tree builder and comprehensive analysis capabilities, including an integrated event tree analysis module. Powerful reporting, charting and import/export facilities are included.
FaultTree+ also includes our Markov analysis program as an integrated module. 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.
AvSim+
A sophisticated Monte Carlo simulation package for analyzing systems availability and reliability problems using fault trees or reliability block diagrams. The AvSim+ Monte Carlo simulator engine is the result of 16 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 modeled using standard analytical techniques.
AvSim+ also includes an integrated Weibull analysis module. The analysis of failure or repair data can be achieved in a visual environment using the Weibull module. The data can be fitted to various failure or repair distributions and displayed in graphical form.
RCMCost
Reliability Centered Maintenance is a technique that focuses on the optimization of maintenance procedures with respect to cost, safety or environmental goals. RCMCost provides a visual environment in which to identify critical equipment through a failure mode effects and criticality analysis (FMECA). A simulation facility calculates the effects of ageing, labor costs and the costs of spares and outages in relation to preventive maintenance and inspections.
lccWare
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.
Hazop+
One of the commonly used techniques in the preliminary phase of a safety study is a hazard and operability study. Hazop+ 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.
RiskVu
RiskVu is designed to provide a high level interface to the FaultTree+ program. This allows it to be used as a ‘Living PSA’ (Probabilistic Safety Assessment) tool or as a risk monitor. It may also be used as a management tool to allow users to try out ‘what-if’ scenarios without knowing anything about the underlying fault and event tree models created in FaultTree+.
NAP
The Network Availability Program (NAP) enables users to predict the availability and reliability of communication networks. The NAP network availability model utilizes 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.
FRACAS+
The Failure Reporting Analysis and Corrective Action System (FRACAS) can be used to collect, record and analyze 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.
A major problem for many organizations stems from the fact that similar failures occur on many sites and are recorded by many individuals in many different ways. The use of a FRACAS system will solve this, as well as produce an accurate and accessible failure and corrective action history.
IsoLib Parts Libraries
IsoLib has been developed to be used in conjunction with Isograph's existing range of powerful analytical tools.
The IsoLib Parts Libraries contain many thousands of modern electronic and non-electronic parts and provide a comprehensive source of failure data for users of Isograph’s reliability products. The libraries have been constructed by electronic and reliability engineers from manufacturers’ datasheets and other sources, or taken directly from existing public sources.
AttackTree+
Attack trees allow threats against system security to be modeled 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 modeled 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+ is an invaluable tool to system designers and security personnel. AttackTree+ 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.
Project Management
The Project Management program is a powerful tool that can be used to manage project files associated with Isograph software products. It provides full project control and historical tracking to those using the software in a corporate or enterprise situation.
