Windchill RBD

formerly Relex OpSim

Analyze reliability, availability and cost using advanced RBD system modeling

Windchill RBD (formerly Relex OpSim) combines easy-to-use diagramming tools with powerful optimization and simulation calculations to analyze the performance of complex, repairable and non-repairable systems. Model a wide range of complex configurations, including series, redundancy or load-sharing, then engage the powerful calculation engine to compute reliability, availability, maintainability and life cycle costs, while optimizing spares inventory and preventive maintenance intervals.

Diagramming Interface Powerful Calculations. At the core of Windchill RBD is a highly intelligent computation engine that utilizes analytical (exact) calculations and/or Monte Carlo simulation to produce fast, accurate results. For repairable systems, account for repair resource limitations, imperfect maintenance, and onsite or offsite spares to calculate a range of maintainability and cost metrics. Optimize spares inventory and maintenance intervals to reach a specified goal of minimized costs, maximized reliability or maximized capacity.

Reliability vs Time Efficient Modeling. Quickly build simple or complex diagrams using drag-and-drop techniques in the intuitive visual diagramming interface. Create libraries to store and reuse common blocks, or entire reliability block diagrams. Navigate large diagrams using the filter capabilities in the tabular view to quickly access individual block parameters. Utilize sub-diagrams to better organize the analysis and centralize repeat logic. Windchill RBD also supports a verification utilitity to ensure required parameter information is entered for all blocks, and that connections are complete and valid.

Professional Outputs. Windchill RBD is supplied with a range of industry standard reports and graphs. Easy-to-use Report and Graph Wizards provide complete user customization of outputs to fit your specific needs, without the need for IT experts. Once complete, reports and graphs can be printed or saved directly to Microsoft Word or Excel, and Adobe PDF.
