Isograph Availability Workbench 5.0: Integrated Asset Performance & Maintenance Optimization Software

Isograph Availability Workbench 5.0 is a powerful, integrated simulation software suite for improving asset performance. It combines maintenance and spares optimization, availability studies, Reliability Centered Maintenance (RCM), life cycle cost evaluation and accelerated life testing in a single environment. Version 5.0 (with minor update 5.0.0.2) introduces enhanced Monte Carlo simulation for complex system dependencies, a new Life Cycle Cost module, a Failure Wizard for building Weibull models without data, and multiple performance improvements.

???? Primary Users

This professional asset performance software is designed for:

Reliability & Maintenance Engineers optimizing preventive maintenance intervals, spares holdings, and crew manning levels.
Asset & Plant Managers predicting system availability, life cycle costs, and production throughput.
Functional Safety & RCM Specialists performing Reliability Centered Maintenance (RCM) and Failure Mode Effects Analysis (FMECA).
Life Cycle Cost (LCC) Analysts evaluating the financial impact of maintenance strategies and operational scenarios.
Defense, Energy & Manufacturing Engineers managing complex, safety-critical or production-critical physical assets.

⚡ Key Features & Capabilities

???? Integrated Modules (All-in-One Suite)

AvSim (Availability Simulation) – Monte Carlo simulation of complex systems using Reliability Block Diagrams (RBDs) or Fault Trees. Models spares dependencies, switching delays, buffering, opportunistic maintenance, and multi-product capacity (oil, gas, water) .
RCMCost (Reliability Centered Maintenance) – FMECA-based RCM analysis. Identifies critical failure modes, compares cost/safety/operational benefits of different maintenance intervals, and recommends optimized maintenance policies (preventive, predictive, inspection, redesign) .
Weibull Analysis – Analyze historical failure data (SAP/MAXIMO connectivity), fit Weibull, lognormal, or normal distributions, multi-phased Weibulls, confidence bounds (MLE), generate reliability/PDF/failure rate plots .
Life Cycle Cost (LCC) – Compares capital, operational, maintenance, spares and downtime costs across multiple scenarios; integrates with availability simulation to quantify ROI of design alternatives .

???? Version 5.0 Enhancements

LCC Module – New module integrated into the suite .
Failure Wizard – Creates Weibull distributions from engineering estimates (no data required) .
Advanced Monte Carlo Simulation – Calculates “time in standby”, supports hot/cold/warm standby states for RBD/Fault Tree elements .
Report Designer – PDF/A-2 compliant, custom SQL queries, graph value labels; improved Report Wizard .

???? Interoperability & Data Management

SAP & MAXIMO Integration – Direct data download; automatically build failure models from your CMMS/EAM .
Data Link Manager (DLM) – Bi-directional links to Jama Connect® and IBM Rational DOORS® for requirements traceability (supports ISO 26262, IEC 61508, ARP 4761) .
Excel Import/Export – Dramatically improved spreadsheet import speed for large workbooks .
