In knowledge representation by fuzzy rule based systems two reasoning mechanisms can be distinguished: conjunction-based and implication-based inference. Both approaches have complementary advantages and drawbacks depending on the structure of the knowledge that should be represented. Implica-tive rule bases are less sensitive to incompleteness of(More)
The paper reports the results of a joint project on evolutionary design of reinforced concrete structures in tall buildings. It has been conducted at the Center for Concrete Structures at the Darmstadt University of Technology in Germany and in the School of Information Technology and Engineering at George Mason University. Its ultimate objective is to(More)
Today's building industry not only demands more and more reduced construction time on building site, but also an advanced and mostly construction attendant design phase. Even though there is software available to support design processes in distributed environments, most applications only support simple document based exchange of information. In this paper(More)
Complex engineering tasks are rarely unique in their solution. The question is not to determine a single solution – it is more to retrieve an optimal solution. Automated, software-based optimization technologies turned out to be a very promising and applicable solution for the class of non-deterministic optimization problems. In this paper a generic(More)
