The Huge and Advanced Engineering as Trans-science

Abstract

The concept of trans-science by A. Weinberg is reexamined in connection with a huge and advanced science project, KEK B factory. Classification of the trans-science is introduced which implies the similarity with the uncertainty matrix approach of A. Stirling. The similarity is extended to the post normal science of J. Ravetz. Treatment of these uncertainties is a key issue for a successful huge engineering project.
