The Modeling and Simulation Frontier for
Multidisciplinary Design Optimization
In addition to its historical objective of serving as the premier forum for multidisciplinary design optimization (MDO) research and development, the AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference has the objective of cross-fertilizing the MDO and modeling and simulation (M&S) fields. Some insight into the perspectives of these two communities is gained from an examination of their basic definitions.
One popular definition of MDO is “a methodology for the design of complex engineering systems and subsystems that coherently exploits the synergism of mutually-interacting phenomena.” The 1998 AIAA MDO Technical Committee White Paper on Industry Experience with MDO divided the subject into four broad categories: Analysis Capabilities & Approximation, Design Formulations & Solutions, Information Management & Processing, and Management & Cultural Implementation (http://endo.sandia.gov/AIAA_MDOTC/sponsored/mao98_whitepaper.html). More background is available on the MDO Technical Committee Web site.
A concise definition of M&S is “the use of models, including emulators, prototypes, simulators, and stimulators, either statically or over time, to develop data as a basis for making managerial or technical decisions.” Modeling is the “application of a standard, rigorous, structured methodology to create and validate a physical, mathematical, or otherwise logical representation of a system, entity, phenomenon, or process,” where simulation is “a method for implementing a model over time.”
Although a decade or two ago one could draw sharp distinctions between the two fields, today there are many topics of common interest, e.g. modeling methodologies, uncertainty analysis, integration techniques, visualization tools, and optimization strategies. The MDO community has traditionally placed greater emphasis on the performance of engineering systems, whereas the M&S community has focused more on the interactions of humans with systems, particularly for command and control. This conference provides the MDO and M&S communities the opportunity to explore fresh perspectives on the challenges they both face.
The major topic areas for this conference have been organized into four broad topics: Modeling, Simulation, and Analysis Methods; Integration Methods; Optimization Methods; and Applications. Papers submitted to the first three topics should have their primary focus on presenting new methods and tools, whereas papers submitted to the applications area should have as their primary focus the engineering or decision support results.
