Formalisms For Fusion Belief in Design

The nature and scope of fusion of imprecise data in the design is explored and discussed with subjective view of de Finetti. Every stage in the design process includes a level of approximation and is typically high in the preliminary phase. Engineering projects often are modified in several design iterations before being completed. Information received from many groups or experts working on a project will often necessitate changes in a design. The interaction between different groups associated with a design project often takes the form of an informal fusion of data. This form of interaction commonly arises when engineering information is imprecise. For the fusion of belief the theory of Dempster and Shafer is used. DS theory generalises the Bayesian rule and provides the mechanism for the fusion of information.
