To provide a scientific foundation for the development of design models (Decision-Based Design) and methods (Decision Support Problem Technique) and design support tools (Decision Support Problems). This covers two of three areas that were deemed to be crucial to reforming the practice and teaching of engineering design.1 Specifically, provide an opportunity for students to learn how

  • to negotiate solutions to open problems. Open problems are characterized as those which are open to the environment, for which there may be multiple solutions or for which no solution may exist;
  • to use mathematical models in design (make connection between engineering science and engineering design);
  • to design the specifications and configure an engineering system using available assets (existing components or modules);
  • identify, model, solve decision problems.
Desired Student Outcomes:
  • Learn how to negotiate design open systems from a decision-based perspective.
  • Develop an appreciation for the scientific foundations that are required for developing a decision-based approach for designing open engineering systems.
  • Develop an appreciation of the state-of-the-art in decision-based design and Concurrent Design research and practice.
  • Develop the ability to critically evaluate literature and use this analysis to identify research issues worth investigating.
  • Open engineering systems
    • Identification, characteristics, metrics (robustness, modularity, adaptability, mutability), research issues.
