Method for generating a graph model for monitoring machinery health

A method to enable diagnostics and/or prognostics of health of an equipment platform, said method comprising the steps of:

• extracting a plurality of entities of the equipment platform from two or more different input sources;
• analyzing the plurality of entities extracted from the two or more different input sources to generate a graph database having one or more nodes representing the plurality of entities of the equipment platform, and having one or more edges connecting a parent node with a plurality of child nodes and defining a parent-child relationship there between, and wherein the generated graph database is used to construct a connected graph that is representative of the graph database and the connected graph dynamically changes based on changes in the graph database, wherein the connected graph comprises a plurality of connected sub-graphs, the connected sub-graphs pertaining to different types of input sources of the two or more different input sources;
• and
• performing the diagnostics and/or prognostics of the equipment platform based on the connected graph, wherein performing the diagnostics and/or prognostics of the equipment platform comprises:
• receiving a query which identifies at least one entity of the plurality of entities of the equipment platform, wherein the at least one entity is represented as a first node in the connected graph and the first node is connected via edges to a plurality of second nodes representing a plurality of children entities related to the at least one entity;
• and
• recursively executing the received query on the connected graph starting from the first node representing the at least one entity identified from the received query, and on each of the plurality of second nodes until all children of the at least one entity are traversed so as to output data corresponding to the plurality of children related to the at least one entity.
