Towards an engineering port ontology for system design and simulation. - 136 p.

Thesis (Ph.D.)--Carnegie Mellon University, 2004.

This thesis focuses on a component-based formalism and representation for computer aided design applications, especially on the interfaces between components. The inclusion of a comprehensive interface representation supports many common design activities such as refinement, composition, and compatibility checking. The elemental unit for defining such interactions and interfaces is a port.

502 $a Thesis (Ph.D.)--Carnegie Mellon University, 2004.
520 $a This thesis focuses on a component-based formalism and representation for computer aided design applications, especially on the interfaces between components. The inclusion of a comprehensive interface representation supports many common design activities such as refinement, composition, and compatibility checking. The elemental unit for defining such interactions and interfaces is a port.
520 $a Ports are defined as locations of intended interaction between a component and its environment. During design of systems, the emphasis is on generating the system architecture: the configuration of sub-systems and the interactions between them. Ports play an important role at this stage of design. They are convenient abstractions for representing the intended exchange of signals, energy or material; they can be applied at different levels of detail, across different energy domains, and to all aspects of design: form, function, and behavior. But to play this versatile role, ports need to be represented in an unambiguous yet flexible fashion for accommodating different disciplines and perspectives.
520 $a In this thesis, the semantic structure for such an unambiguous representation is introduced: a port ontology. The ontology formalizes the conceptualization of ports such that engineers and computer aided design applications can reason about component connections and interactions in system configuration. It defines ports in terms of form, function and behavior attributes and further includes axioms that can be used to support a variety of engineering design tasks, such as port refinement, port compatibility checking, and the instantiation of interaction models.
520 $a The contribution of this research work is to validate and verify the hypotheses we have proposed that answer the research questions: "How can one represent the interaction of systems formally, comprehensively, and unambiguously?", "How can this representation be used to further improve and systematically guide component search, design refinement, and iterative design?" and "How can the interaction representation be used to explicitly capture and formally infer composition, compatibility checking, and interaction model selection?" The development of the port ontology answered the first question. And a LEGO system design example introduced in this thesis provides the initial validation for the second and third questions.
