Implementing Qualitative Reasoning for Structural Design Using Constraint Propagation

Abstract:

All designs begin with qualitative reasoning and therefore, this activity has an important influence upon subsequent quantitative stages. In structural design, qualitative reasoning starts with assumptions that may become invalid as reasoning progresses. Furthermore, the presence of multiple design criteria leads to tradeoffs that also change as reasoning progresses. We present an algorithm for dynamically managing design spaces through constraint propagation and special strategies for conflict resolution. An example in preliminary bridge design illustrates several aspects of the approach.
