dc.description.abstract The potential benefits of mathematically predicting and analyzing the integrated behavior of product concepts throughout the design synthesis cycle are widely recognized. Better up-front integrated design will not only reduce development time and cost, but also will yield higher quality products with improved performance. Many academic researchers and companies have attempted to develop integrated simulation environments, and it has been observed consistently that significant difficulties arise because of the large scale, complexity, rate-of-change, heterogeneity, and proprietary barriers associated with product design synthesis. However, the focus of most integration efforts has been on enabling technology, while the process of how integrated systems are constructed has not been questioned. The literature acknowledges that it is very difficult to represent and structure emergent processes using explicit system definition techniques like those that have been almost universally adopted. The belief that design synthesis is an emergent system definition process drives the search for a different approach to building integrated design simulations. Inspired by a vision of the World-Wide Web as an emergent informationnetwork building environment, a World-Wide Simulation Web concept is proposed for defining an emergent, integrated, simulation-building environment. Participants should be able to make interfaces to local sub-system simulations parametrically operable and accessible over the Internet. Furthermore, any participant should be able to make relationships between parameters in different simulation interfaces or to create additional models that bridge interfaces to different simulations distributed over the Internet. The DOME (Distributed Object-based Modeling Environment) project has developed a software infrastructure for the purpose of refining and testing emergent simulation definition concepts. A federating solving mechanism has been developed that allows local solvers to respond in a manner that is consistent with the overall system structure even though there is no centralized coordination of the simulation. Results from several pilot studies support the belief that an emergent, decentralized approach to building integrated simulations can resolve many of the difficulties associated with integrated system simulation. en
