Fuzzy evidential influence diagram and its evaluation algorithm

摘要

Fuzzy influence diagrams (FIDs) are graphical models that combine qualitative and quantitative analyses to solve decision-making problems though some shortcomings that need to be corrected still remain. One is to guarantee the exactness as node evaluation in high-complexity influence diagrams (IDs) need to be combined with a number of expert evaluations. However, traditional FIDs can only process a single expert's evaluation. The other is that they use incomprehensive evaluation criteria to score nodes in complex systems with many different relationships receiving the same score, which does not reflect their differences.
