Using the concept of credibility measure, this paper proposes a mean-variance hybrid-entropy model which measures the risk of local deviation from the mean as well as the risk of overall deviation fro
In this paper, we investigate the hesitant fuzzy hybrid information aggregation operators in which the attributes are in different priority level.Considering the double impact of priority level of att
This paper analyses the correlative relationship between the financial indicators and non-financial indicators of power grid enterprises, and accordingly sets up an evaluation indicator system of the
According to the generalized distance minimum principle, a selecting model for the optimal evaluation method is built.Based on the model, the rough set theory is taken to be more suitable than the ent
Project scheduling problem is to make a schedule for allocating the loans to a project so as to balance the total cost and the completion time under some constraints.This paper mainly researches on an
Uncertain set is a set-valued function on an uncertainty space, and attempts to model unsharp concepts.Firstly, a new uncertain set N(a, b) called normal is defined, and the parameters a and b2 are pr
Uncertainty theory provides a new tool to deal with uncertainty.The paper employs it to propose a new uncertain insurance model with variational lower limit, and give a ruin indexes and uncertainty di
Uncertainty exists in many two-sided matching problems, as a result, there is a need to model the uncertainty.Firstly, this paper introduces a model based on the uncertainty theory using uncertain pre
This paper is concerned with a parametric optimal control problem of multidimensional uncertain linear quadratic model.We propose an approximation method for solving the optimal parameter of such a mo
The paper further study uncertain propositional logic based on uncertainty theory.Firstly, an equivalent definition of the truth value of uncertain formula is presented by introducing generalized prod
