12 th Face-to-Face Meeting ASME Design Engineering Technical Conferences September 2001 An Open Workshop on Decision-Based Design Wei Chen Associate Professor University of Illinois at Chicago Chicago, IL Kemper Lewis Associate Professor State University of New York (SUNY)Buffalo Buffalo, NY Linda Schmidt Associate Professor University of Maryland College Park, MD

12 th Face-to-Face Meeting ASME Design Engineering Technical Conferences September 2001 What is the DBD Perspective? Decision-making is a vital part of design. DBD practitioners view design as a decision-making process that maximizes the value of a designed artifact to both the producer and the end-user. Design occurs in an environment characterized by ambiguity, uncertainty and risk, complicating the decision-making process. DBD processes emphasize establishing value systems to rank expected outcomes of design decisions and incorporating uncertainty and risk handling in predicting the expected outcomes.

12 th Face-to-Face Meeting ASME Design Engineering Technical Conferences September 2001 Open Workshop Goals Synthesize a sound theory of Decision-Based Design. Determine the role of decision-making in design. Develop consensus on defining the DBD perspective. Establish the role of DBD within design theory and methodology research. Build a repository of foundational materials that illustrate design as decision-making. Establish a useful relationship between DBD and other theories (e.g., physics, mathematics, information and management science) Transfer DBD decision support methods and tools into industry.
