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 incorporating FaultTree+

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.

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.

Network Availability Prediction

Network Availability Prediction enables users to predict the availability and reliability of communication networks. The  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 Network Availability Prediction  also provides criticality rankings that identify weak spots in the network. Network Availability Prediction  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 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.
