Title: Complexity index methodology for the analysis of run life performance
Inventor: RIVAS OLEGARIO S
IPC: G06Q10/06
Filed: 2001-01-19
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. The use of individual complexity index values permits the addition, subtraction or changing of components in a given system without losing predictability of the desired aspect, e.g. run life.
