Patent Images
1. A method to predict remaining life of a target equipment, the method comprising:
- receiving target information regarding a behavior of the target equipment, said target information including at least a target operational history;
identifying from a database at least one piece of peer equipment having similarities to the target equipment based upon said behavior of said target equipment;
retrieving from the database peer data of said peer equipment having a relationship to the behavior of said target equipment, wherein said peer data includes at least peer operational data;
evaluating a similarity of the relationship between the peer equipment and the target equipment using said peer data and said target information;
creating at least one model based upon the similarity;
predicting the remaining life of the target equipment based upon the models using an evolutionary search of said model for at least one iteration; and
generating a signal corresponding to the predicted remaining life of the target equipment.

Abstract
A method to predict remaining life of a target is disclosed. The method includes receiving information regarding a behavior of the target, and identifying from a database at least one piece of equipment having similarities to the target. The method further includes retrieving from the database data prior to an end of the equipment useful life, the data having a relationship to the behavior, evaluating a similarity of the relationship, predicting the remaining life of the target based upon the similarity, and generating a signal corresponding to the predicted remaining equipment life.

16. A system to predict remaining useful life of a target equipment, the system comprising:
-
a database comprising peer data for at least one peer equipment and target data for said target equipment; a processor in signal communication with the database; a computational model application for executing on the processor, the computational model performing a method, comprising; receiving information regarding a behavior of the target equipment, said behavior including at least operational history; identifying from the database at least one piece of peer equipment having similarities to the target equipment; retrieving from the database peer data having a relationship to the behavior; evaluating a similarity of the relationship; creating at least one model based upon the similarity; and predicting the remaining useful life of the target equipment based upon the similarity using an evolutionary search of said model for at least one iteration; wherein the processor is responsive to the computational model application to generate a signal corresponding to the predicted remaining useful life. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
