摘要

A signed directed graph (SDG)-based computation procedure is proposed in this paper to predict the effects of one or more fault propagating in a multiloop process system. The conventional version of qualitative simulation techniques1 is modified to identify not only the locations of fault origins but also their magnitude levels. In addition, a computer algorithm is presented to generate the IF-THEN inference rules automatically according to the anticipated fault propagation behaviors. The effectiveness and feasibility of this approach has been tested with three case studies. Two of them are concerned with level control systems and the other an exothermic continuously stirred tank reactor (CSTR) with temperature and level control loops.
