Distribution network maintenance planning

A system for maintaining an infrastructure of components, the system comprising:

• at least one memory device;
• at least one processor connected to the memory device,
• wherein the processor is configured to:
• receive structured data, unstructured data, and infrastructure data from a database;
• run 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 λexp (Σi=1kβiZi), where λ is any positive real number, Zi is a covariate, i is an index, k is a maximum number of the index, and βi 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;
• establish 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;
• compare health indices of the at least one established maintenance plan;
• and
• select a plan, among the at least one established maintenance plan, whose health index is a maximum among the compared health indices.

A computer program product for maintaining an infrastructure of components, the computer program product comprising a storage medium readable by a processing circuit and storing instructions run by the processing circuit for performing a method, the method comprising:

• receiving structured data, unstructured data, and infrastructure data from a database;
• running 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 λexp (Σi=1kβiZi), where λ is any positive real number, Zi is a covariate, i is an index, k is a maximum number of the index, and βi 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.
