Analysis Based on the Exact System Reliability Function
BlockSim uses an exclusive algorithm pioneered by ReliaSoft to algebraically compute the exact system reliability function for even the most complex systems. This makes it possible to perform a number of system reliability investigations analytically, without resorting to simulation.
System Reliability Metrics and Plots
You can use the convenient Quick Calculation Pad (QCP) and plot sheets to calculate and visualize key system reliability metrics such as:
- Reliability and probability of failure
- Reliable life (i.e., time for a given reliability)
- BX% life (i.e., time for a given unreliability)
- Mean life
- Failure rate
The Quick Calculation Pad (QCP) has been updated and redesigned in the Synthesis version. The new interface provides a "Calculation Log" that works like a paper roll in an adding machine, allowing you to record the results from a series of different calculations and then copy/paste the information as needed.
Minimal Cut Sets
For each analytical diagram, BlockSim identifies the unique combinations of component failure that can cause system failure. These minimal cut sets can be used to understand the structural vulnerability of a system.
Reliability Importance Measures and FRED Reports
BlockSim provides a set of Reliability Importance plots designed to show the relative importance of each component with respect to the overall reliability of a system.
The software also offers FRED Reports (Failure Reporting, Evaluation and Display), which provide an intuitive graphical presentation of key reliability metrics, with color-coding to identify the ones that may be critical for system improvement. In Version 10, FRED reports are now integrated with the Failure Modes and Reliability Analysis (FMRA).
Optimum Reliability Allocation
BlockSim also provides a tool dedicated to helping you find the most effective component reliability allocation to meet a system reliability goal. The new centralized utility makes it easier than ever to enter and manage all of the information required to use the innovative Cost Optimized allocation method that’s still available exclusively in BlockSim. This feature now also supports Equal and Weighted reliability allocation methods. Start at the system level and click your way to the component or failure mode level while the software automatically computes the target reliability for each item/mode and transfers it to the next.
This utility is also integrated with the FMRA in Version 10.
