Development of a Knowledge Management Methodology based on Argumentation Model on the Safety of Geological Disposal(<Special Issue>Manufacturing and Information Technology)

Abstract

Conventional methodologies to manage safety of engineering plants, such as manuals and databases of past failures, are not always sufficient for structured visualization and flexible updating of knowledge. This paper proposes a new knowledge management methodology using argumentation model, which consists of chains of arguments and counter-arguments on safety. The results of some case studies for structuring knowledge in the field of geological disposal successfully show that safety concept can be visualized with the new media, argumentation model. In addition, the results of dry-run community shows that the argumentation models can be flexibly structured and altered by the activity of communities of people who have interests in geological disposal.
