System performance analysis often demands more than traditional reliability block diagramming (RBD) tools can juggle. It’s critical to take into account the relationship between components. How does the reset of one component affect the whole system? How can you identify potential failures? How can you accurately predict and manage the risks around assets that could fail and cause unnecessary and expensive downtime? How can you resolve uncertainty in multi-stage manufacturing systems?

The Reliability module in ExtendSim Pro is the missing link bridging reliability block diagrams with the pinpoint accuracy of simulation to mimic the behavior of systems using dynamic reliability modeling. Maintenance reliability professionals, asset managers, and predictive maintenance teams are turning to simulating RBDs in ExtendSim to help manage their asset reliability program, reduce rate failures, optimize alternate flow paths, deal with intermediate product storage, and improve the reliability of plant assets.
