CORBA-based object-oriented framework for distributed system design

A generic framework for designing large, complicated systems is formulated, implemented, and used in the design of mechanical systems, including a pre ssure vessel, an: automotive hybrid powertrain, and a tracked vehicle. The framework supports: simulation-based design, distributed and heterogeneous computing resources, custom and legacy simulation and analysis codes, recon figurability of the design problem, and security of operation across untrus ted networks. The framework also facilitates the implementation of methodol ogies for system design that employ design model partitioning and coordinat ion, as well as a variety of models and search algorithms. Common Object Re quest Broker Architecture (CORBA) middleware for distributed, object-orient ed applications was selected to develop and implement the framework. Framew ork components include subsystem model, design model, search engine, design model partitioning, design coordination, and user interface.
