DOME (Distributed Object-based Modeling Environment)
DOME offers a fundamentally new approach to integrated modeling and simulation. Much as the worldwide web enables global access to static information, project DOME (Distributed Object-based In a user-friendly web-based environment, DOME integrates the efforts of hundreds of developers working on radically different platforms in widely dispersed locations. All designers participate simultaneously in the modeling process, using their preferred tools and methods. While maintaining information integrity, DOME predicts and models the integrated characteristics of large, complex, rapidly-evolving products and systems. DOME’s seamless infrastructure provides the management controls of a centralized system while preserving the responsiveness of a locally autonomous system.
As head of CIPD's DOME initiative, Professor Wallace's research interests include environmentally-conscious product design, integrated computer-aided design, industrial design and aesthetics, visual communication, and product design and new media education. |

Current Projects
Advanced Search Mechanisms: provide robust techniques for locating dynamic models in the worldwide simulation web, even as they undergo rapid change and development.
Distributed Probabilistic Simulation: allows simulations to run either deterministically or probabilistically, while addressing the additional computational load of probabilistic simulation.
Pareto Optimization: provides better understanding of tradeoff options when a design has many goals; multi-modal Pareto analysis technique appears to outperform other published algorithms.
Benefits
DOME dramatically increases the quality
of information shared by all members in a design effort.
Speed
Design modifications are communicated instantaneously—changes that once
took days or weeks to propagate through the development system now do so in
seconds.
Communication
Each participant sees design changes in terms of preferred tools and applications.
For example, if an auto engineer changes a design, the change is reflected
in the finance department as a change in cost.
Security
Proprietary knowledge is safeguarded. Each participant sees only the appropriate
and necessary information.
Key Advances
- Build Application: lets users create multiple interfaces for existing models, and create integrative models between simulations.
- Deploy Application: sets permissions on interfaces, and moves models to servers.
- Server Application: solves the execution of distributed models, and manages the interactions of multiple, distributed clients.
- Run Application: lets users browse the simulation web and execute models.
