The Application of Decision Influence Diagrams in Device Reliability Analysis |
| |
| Abstract: | The decision influence diagram is a new graphical representationmethod of decision analysis.It uses directed acyclic graphs to represent the rele-vant relationships among decision variables,stochastic variables and objective fun-ctions,and to make analyses of inference,information and sensitivity.This ana-lysis of influence diagrams is used to study the problems of device reliability inthis paper. |
