This paper gives a Dempster-Shafer (DS) theoretic approach for realizing decision support in safety-control for large-complex systems. We show that rules of combination in the conventional framework of the DS theory are not always adequate for representing various knowledge on characterisitics of systems which must be controlled. This paper extends the current framework of the DS theory into a general one so that it can reflect operators' system-specific knowledge. Usefulness of our extension is proven by taking a safety-control problem as an example.
