Sarrail 94010, Creteil, France Compiegne Cedex, France ABSTRACT Many realistic applications are temporally rich domains. The classic formalisms based on atomic temporal primitives, such as interval or point, are insufficient to reflect the diversity and the evolution of real world situations. We propose to build, out of an initial set of domain- independent temporal structures and relations, more sophisticated domain-dependent layers incorporating the semantic of the considered application. The temporal constraint propagation is reduced to the needs of the discourse to model. Thus, the system is able to reason in real-time. Our approach is applied in order to represent time aspects in diagnosis and therapeutic tasks involved in a patient monitoring process. INTRODUCTION Time is an important element in knowledge representation. Realistic applications are dy
