In this paper, we discuss dynamic integration of multiple aspects,
i.e., integration accomplished according to progress of design. It is not
prepared in advance, but created in design processes. Firstly, we introduce
our model of design processes that is based on a logical framework. Secondly,
we define aspects in the logical framework. An aspect is represented as a
tuple of theory and vocabulary in the logical framework. In particular
knowledge in analytical aspects is represented as virtual logical theory.
Thirdly, we propose integration of aspects by abduction that is another
approach than integration of models. Abduction defined with multiple aspects
integrates aspects by superposition of hypothesis which is identification of
instantiated entities in hypothesis. It also examines connectivity of
hypotheses by explanatory coherence. Since superposition of hypotheses and
theories used in abduction tell us how aspects are integrated in design, they
can contribute to re-organize aspect knowledge-bases.
