The integrated reliability and safety analysis suite at the heart of TMG’s modelling practice. Reliability Workbench combines Prediction, FMECA, Reliability Block Diagrams, FaultTree+, Event Tree, Markov, Weibull, Reliability Growth and Allocation in a single environment — SGS-TÜV certified for ISO 26262 and compliant with IEC 61508, ARP 4761 and AIAG & VDA standards. https://mantua.group/isograph-software/reliability-work-bench-weibull-module/

The flagship simulation suite for availability, maintenance and life-cycle cost optimisation. RCMCost applies reliability-centred maintenance methodology over a Monte Carlo engine, helping engineers determine the most cost-effective inspection, replacement and spares strategies, quantify the value of redundancy, and forecast availability against throughput targets across the full asset life cycle. https://mantua.group/isograph-software/isographs-rcmcost/

Turning raw failure data into predictive insight. Network Availability Prediction (NAP) applies an extended RBD methodology to model communications and distribution networks; AvSim delivers Monte Carlo system simulation with capacity and spares logic; and the Weibull module fits historical failure and repair data to drive both — straight from CMMS, FRACAS or ERP exports.

Specialised analysis for risk and economics. AttackTree applies attack-tree methodology to model cyber and physical security threats and quantify mitigation effectiveness, while the Life Cycle Cost module integrates predicted maintenance and operational costs with user-defined cost equations for time-dependent, whole-of-life cost analysis. Together they support investment business cases under ISO 21434 and asset-management decision frameworks.

Process safety and production assurance, integrated. Hazop+ provides a familiar visual environment for hazard and operability studies with extensive reporting and action-tracking facilities. The Process Reliability module then quantifies the impact of equipment failures on production output — translating reliability metrics directly into throughput, capacity loss and economic consequence for process and manufacturing operations.

Connect the model to the source of truth. Data Link Manager and the SAP- and Maximo-certified portals stream live failure, work-order and asset data into AWB and RWB, while Accelerated Life Testing (ALT), the open API and the Enterprise database extend that reach to test rigs, custom systems and centralised, multi-user, version-controlled deployments.
