Abstract
A method and system that can be used to automatically calculate and generate performance analysis charts, including a reliability curve is disclosed. The method and system may be used to selectively convert performance records data from a database into graphs and charts reflective of a performance analysis. The invention also provides a tool and method that can be used to predict the effective life or run time of a component, such as a drill bit, based calculated reliabilities for similar components.

A performance analysis tool for analyzing data in a set of performance records and generating a reliability curve based on the data, each performance record including component condition data relating to a functional condition of at least one component of a system, the performance analysis tool comprising:
- a filter adapted to select from the set of performance records a set of desired records based on filtering criteria provided as input;
- a calculator adapted to process selected data from the desired records to obtain performance analysis data including values for a reliability curve;
- and
- a graphics generator adapted to generate the reliability curve.
