    • A Formal Two-Phase Method for Decomposition of Complex Design Problems 

      Li Chen; Zhendong Ding; Simon Li (The American Society of Mechanical Engineers (ASME), 2005)
      This paper presents a formal two-phase decomposition method for complex design problems that are represented in an attribute-component incidence matrix. Unlike the conventional approaches, this ...

    • An Efficient Weighting Update Method to Achieve Acceptable Consistency Deviation in Analytical Target Cascading 

      Jeremy J. Michalek; Panos Y. Papalambros (The American Society of Mechanical Engineers (ASME), 2005)
      Weighting coefficients are used in analytical target cascading (ATC) at each element of the hierarchy to express the relative importance of (a) matching targets passed from the parent element ...

    • Topology Optimization of Multicomponent Beam Structure via Decomposition-Based Assembly Synthesis 

      Naesung Lyu; Kazuhiro Saitou (The American Society of Mechanical Engineers (ASME), 2005)
      This paper presents a method for synthesizing multicomponent beam structural assemblies with maximum structural performance and manufacturability. The problem is posed as a relaxation of ...

    • A Constraint Satisfaction Problem Approach Linking Function and Grammar-Based Design Generation to Assembly 

      Linda C. Schmidt; Hai Shi; Sameer Kerkar (The American Society of Mechanical Engineers (ASME), 2005)
      This work presents a constraint satisfaction problem (CSP) approach to design, integrating a function-based design generation algorithm to a geometric modeler. Our long-term goal is to create a ...

    • Characterization and Coordination of Point-line Trajectories 

      Kwun-Lon Ting; Yi Zhang; Ruj Bunduwongse (The American Society of Mechanical Engineers (ASME), 2005)
      A point-line refers to a rigid combination of a directed line and an endpoint along the line. To trace a point-line trajectory, one must control not only the trajectory of the endpoint (the ...

    • A Methodology for Model Selection in Engineering Design 

      Rajesh Radhakrishnan; Daniel A. McAdams (The American Society of Mechanical Engineers (ASME), 2005)
      Engineering design consists of a series of stages during which a number of decisions need to be made by the designer. Since the information available to the designer is limited during initial ...

    • A Model-Based Formulation of Robust Design 

      Khalid Al-Widyan; Jorge Angeles (The American Society of Mechanical Engineers (ASME), 2005)
      Laid down in this paper are the foundations on which the design of engineering systems, in the presence of an uncontrollable changing environment, can be based. The changes in environment ...

    • Interactive Product Design Selection With an Implicit Value Function 

      K. Maddulapalli; Graduate Research Assistant; A. Boyars; Engineer; S. Azarm (The American Society of Mechanical Engineers (ASME), 2005)
      We present a new method to aid a decision maker (DM) in selecting the “most preferred” from a set of design alternatives. The method is deterministic and assumes that the DM’s preferences ...

    • An Optimality Criterion for the Structural Optimization of Machine Elements 

      C.-P. Teng; Process Analyst; J. Angeles (The American Society of Mechanical Engineers (ASME), 2005)
