  • Complexity index methodology for the analysis of run life performance
    Patent number: 6704689
    Abstract: A system and method for predicting a specific aspect, such as run life, of a component or system. The system utilizes a variety of complexity index values that are assigned to each component of the system. Each complexity index value is determined according to select physical parameters of the component. The summing of the complexity index values provides a system complexity index value that can be used to accurately estimate, for example, the run life of the system.
