More Analyses and Tools

Phase Diagrams

Reliability phase diagrams represent scenarios in which a system may undergo changes over time.

Markov Diagrams

Markov diagrams model the behavior of systems based on memoryless transitions between states, allowing you to look at partial or degraded working states, and to start analysis in varying states.

Reliability Allocation

The allocation analysis tool helps determine the reliability requirements for individual components/assemblies that would be needed to achieve an overall reliability goal.

FRED Reports

FRED reports provide a graphical demonstration of the reliability and maintainability/availability characteristics of the components in a system and help to identify the components that may require improvement.

Optimum Replacement

The Optimum replacement tool helps to determine the best time to inspect and/or replace components, based on the costs for planned and unplanned maintenance.

Simulation Worksheets

Simulation worksheets can vary values that are used when simulating an RBD or a flowchart, allowing you to investigate the effect of various factors on the simulation results (e.g., how the restocking interval and initial quantity in a spare part pool affect the cost of maintaining a system). The values can be entered manually, or can be transferred from an experiment design folio in Weibull++/ALTA. After simulation, you can transfer the results into the design folio in Weibull++/ALTA for analysis and/or optimization.
