On Chu spaces in uncertainty analysis

A very general algebraic framework, known as Chu spaces, has recently been systematically used in modeling of information flow in distributed systems and in modeling of concurrency in computer science. In this paper, we explo re this framework in the context of uncertainty modeling and analysis. We i nvestigate two important Chu categories in probabilistic and fuzzy systems. We address fundamental questions in the modeling aspects toward applicatio ns. (C) 2000 John Wiley & Sons, Inc.
