| Abstract: | This article attempts to analyze the combination of uncertain pieces of information, particularly, given several pieces of information, each of which is assigned a certainty factor. The problem then is whether it is possible to find the certainty factor associated with the combination result. This problem, even if it has been widely commented on in probability literature from various viewpoints, sounds less analyzed in the framework of possibility or evidence theories. This study investigates various proposals for quantifying certainty qualification and then constructs the certainty assigned for the combination result of initial inputs. First, we shall consider some basic combination modes and then attempt to generalize the result for more general combination modes. © 2004 Wiley Periodicals, Inc. |
