HOMOGENEOUS MODEL OF HETERGENEOUS PRODUCT LIFECYCLE DATA

摘要

A method and system is disclosed for modeling product data related to lifecycle of a product, including an application program interface configured to connect with one or more data sources of different types via one or more computer based product management tools. A digital twin graph is constructed to include a plurality of graphical models of product data with related nodes inter-linked by edges via a linking algorithm. Models of the digital twin graph include an ontological model having nodes of ontological information related to the product data, an instance model having instance nodes related to the product data, and a probabilistic model having conditional probability distribution nodes from which causal and predictive reasoning information is generated.
