What is VDD? Why is VDD important? How do you do VDD? From where did VDD come? Charter of the VDD Committee |

The is the Home Page of the AIAA Value-Driven Design (VDD) Program Committee. The Program Committee consists of representatives of industry, government, and academia who want to explore and expand awareness of VDD. Learn what VDD is, how it works, and why we believe VDD is important. Find out what we have been doing at our meetings and what our plans are for upcoming meetings. If you want to participate in the development of VDD, contact us. |
Value-driven design (VDD) is an improved design process that uses requirements flexibility, formal optimization and a mathematical value model to balance performance, cost, schedule, and other measures important to the stakeholders to produce the best outcome possible.
Here is a link to a presentation that descibes VDD: Value-Driven Design. Feel free to copy these slides, but attribute the work to the committee.
VDD optimizes all stakeholder values expressed in a single mathematical function. The function’s inputs represent attributes important to the stakeholders. Capabilities-based approaches + Robust design may augment VDD (or vice versa).
Optimization is a breakthrough tool for the design of large systems. Optimization leads to the design of the best possible system rather just an acceptable system. For the past twenty years and more, scholars have extensively developed the theory of multidisciplinary optimization applied as a design tool. However, optimization is not used for the design of most system components because it has not been integrated into widely used systems engineering methods. Value-Driven Design creates a context for applying optimization in the design of large systems such as aircraft, launch systems, ships and vehicles.
Value-Driven Design grew from a collaboration of three Technical Committees of the American Institute for Aeronautics and Astronautics (AIAA): the Economics Technical Committee, the Systems Engineering Technical Committee, and the Multidisciplinary Optimization Technical Committee. The goal of the collaboration was to use economic value modeling tools as a method to integrate multidisciplinary optimization into the systems engineering framework. Jim Sturges, Fred Striz and Paul Collopy pulled together the initial effort, beginning in January, 2005. Jay Mandelbaum found interest in VDD among members of SAVE International, "The Value Society". Jim Sturges coined the term Value-Driven Design. A workshop was held at Lockheed Martin's Simulation and Test Systems facility in Orlando in August of that year to scope out VDD and begin to formulate a plan for developing and implementing the tool.
Coming out of the August meeting, the group decided to convene again in October to work through an example of applying VDD. United Technologies hosted the October meeting at their facility in Farmington, Connecticut. At this meeting the team developed a value model for a hypothetical supersonic business jet and derived from this model an objective function to guide optimization of the design of an engine for the jet. At the same meeting, the committee voted unanimously to apply to become a Program Committee within AIAA.
The committee meets at the AIAA Aerospace Sciences Meeting every January and at the AIAA ATIO and Space Conferences every September. We are also supporting a National Science Foundation workshop on Engineered Systems Design in February, 2010.
Following is the charter of the VDD Program Committee.
The purpose of the Value-Driven Design Program Committee is to develop, mature, document, and release a design method that identifies and optimizes the attributes of the product or system of highest value to its stakeholders. Committee members wll discuss and explore the wide-spread use of optimization throughout the design process, from lead systems engineers to designers at CAD stations.
Value-Driven Design (VDD) integrates optimization methods with systems engineering, economic analysis and value management methods. When developed, VDD promises a superior and robust approach to affordability that uses economics as a forcing function, balancing cost, performance, and other design attributes to provide the best design to a wide variety of stakeholders. By using the VDD scorecard, everyone in a program has the perspective to execute the vision of the program leaders.
Specific goals of the Program Committee are to:
