First Claim
1. A method for maintaining an infrastructure of components, the method comprising:
- receiving, by a processor device, structured data, unstructured data, and infrastructure data from a database;
running, by said processor device, at least one statistical and optimization modeler with one or more of;
the received structured data, the received unstructured data and the received infrastructure data, in order to calculate a health index of at least one component of the infrastructure, the health index representing a health attribute of the at least one component, the calculation of the health index of the at least one component of the infrastructure including;
HI (health index)=−
(F×
R+W)×
1, where F is a vector representing failure probabilities of the at least one component in the infrastructure, R represents a spatial correlation value of the at least one component and the W represents a time elapsed since a last maintenance of the at least one component, and 1 represents a vector of ones, wherein the vector F is a function of λ
exp (Σ
i=1kβ
iZi), where λ
is any positive real number, Zi is a covariate, i is an index, k is a maximum number of the index, and β
i is a variable representing one or more of;
an age of the at least one component, a diameter of the at least one component, a length of the at least one component, a number of previous failures of the at least one component;
establishing at least one maintenance plan of the infrastructure, based on the calculated health index, each established maintenance plan being associated with at least one health index;
comparing health indices of the at least one established maintenance plan; and
selecting a plan, among the at least one established maintenance plan, whose health index is a maximum among the compared health indices,wherein a computing system including at least one memory device and said processor device performs the establishing, the comparing, and the selecting.

Abstract
A system, method and computer program product for maintaining an infrastructure of components. The system receives structured data, unstructured data, and infrastructure data from a database. The system runs at least one statistical and optimization modeler with one or more of: the received structured data, the received unstructured data and the received infrastructure data, in order to calculate a health index of at least one component of the infrastructure. The health index represents a health attribute of the at least one component. The system establishes at least one maintenance plan of the infrastructure, based on the calculated health index. Each established maintenance plan is associated with at least one health index. The system compares health indices of the at least one established maintenance plan. The system selects a plan, among the at least one established maintenance plan, whose health index is a maximum among the compared health indices.
