...Ahmed Chowdhury; Lakshmi N.A. Venkatanarasimhan; Chiradeep Sen Graph-based function models used in early-stage systems design usually represent only one operational mode of the system. Currently, there is a need, but no rigorous formalism to model multiple possible modes in the model and logically...

...Ahmed Chowdhury; Lakshmi N. A. Venkatanarasimhan; Chiradeep Sen Modern design problems often require multi-modal, reconfigurable solutions. Function modeling is a common tool used to explore solutions in early mechanical design. Currently, function modeling formalisms minimally support the modeling...

...Xiaoyang Mao; Chiradeep Sen In graph-based function models, the function verbs and flow nouns are usually chosen from predefined vocabularies. The vocabulary class definitions, combined with function modeling grammars defined at various levels of formalism, enable function-based reasoning. However...
