Relationality Design and Relationality-oriented Systems Design

Relationality-oriented system science introduced here is a new research field where we try to understand and grasp systems as substance in which humans, tangible and intangible artifacts are interdependent and function together. We have been conducting research on how to design relationality in complex systems composed of humans, tangible and intangible artifacts, by using evolutionary computation and network science as methodologies. This paper describes the research concept, methodologies of relationality design. As one of research on relationality, we propose a research framework for a social network system that elicits relationality from people’s daily life, grows relation-ality with self-propagation and self-proliferation mechanisms, and enables to promote, manage and operate reproduction of relationality.
