The successful realization of Engineering 4.0 needs the creation of a digital thread with digital twins and contextual knowledge that drives engineering decisions across product design, manufacturing and process operations, and in-service in an integrated fashion. This would require a knowledge-guided engineering analysis with automation and integration of various steps using physics-based simulations, machine learning over data, and formal decision-support tools.
TCS Research is working on building a technology platform that can aid engineers across design and operations in making informed decisions in real time. These decisions are backed by the contextual delivery of knowledge from a digitally curated knowledge base supported by automation across complex tools and data. The technology platform being developed has been tested in diverse environments with considerable benefits and is continuously being enhanced with further research.
The technology stack is developed based on a model-driven engineering framework which allows for formal specification of various entities through appropriate metamodels. This provides the flexibility to define various things at a higher level of abstraction and convert them to executable entities. Our metamodels, carefully developed for the engineering domain involving products, materials, manufacturing processes, and so on, provide a means to define subject-specific ontology. This ontology serves as ‘a semantic language’ for the expression of knowledge and data that helps achieve seamless integration between different elements of design and decision processes as shown in the image. A knowledge model allows for digital curation of knowledge in a machine-interpretable fashion on which in-silico contextual reasoning can be carried out. A process engine is guided by this knowledge to interact with the user and execute relevant tools with data in a seamless decision framework. Finally, past decisions made by the engineers is captured for further development of the knowledge base.
