A designer driven interactive approach was developed for the operability analysis of heat exchanger networks. The method is based on a modified formulation of the problem that takes into account the underlying process structure for the streams of a network, thus reducing the dimensionality of the problem. It explores the characteristics of the two nonconvexity generating mechanisms, and provides a series of analytic rules for their efficient handling. The computer implementation of the developed operability analysis uses object oriented concepts, derived within artificial intelligence, and allows for a transparent, graphics based interaction with the designer. A series of examples demonstrates the various aspects of the proposed methodology. (A)
