Multifactor decision making based on hierarchical variable weights

We firstly analyze the effect of variable weight synthesis. It is proved that the max–min decision-making model is the extreme of a class of variable weight synthesis models. Secondly, we research a class of multifactor decision making problems with variable weight theory, propose the idea of hierarchical variable weight, and establish a multifactor decision-making model based on this idea further. Finally, we discuss a real problem about selecting a suitable candidate. The result shows that this model can satisfy the decision maker.
