Some Comments on and an Extension to Activity Structures for Intelligent Systems

Activity structures are a set of functional structures which may be used to provide a uniform framework for the description of information processing systems. The interaction of some aspects of activity structures is discussed. Intelligent systems, a subset of information handling systems, are the primary emphasis of this work. An extension to the functional structures of the activity structures is proposed. The proposed structure is a met a-structure which affects most elements of an intelligent system. The structure is concerned with describing the way uncertainty in an environment is handled by a system. An example is given which shows the importance of describing the uncertainty handling method(s) of an intelligent system.
