带变量核的分数次积分交换子在变指数Herz-Morrey空间上的有界性

证明了带变量核的分数次积分算子T_(Ω,μ)与Lipschitz函数b生成的高阶交换子[b~m,T_(Ω,μ)]在变指数Herz-Morrey空间MK_(q,p)~(α,λ)(·)(R~n)上的有界性.     

Research on the Efficiency Evaluation for the Board Based on GT-AHP Method

The board of directors is the core of corporate governance mechanism. In order to enhance the operation efficiency of the board, and to further reduce the agency cost, effective appraisal of the efficiency of the board becomes urgent. This paper firstly uses graph transformation and matrix algorithm to analyze the performance evaluation factors of the board and establishes the ordered hierarchy structure of the appraisal indexes. Then, it calculates the index weights with the AHP method. Next, it sets up the efficiency appraisal index system of the board. At last, the paper gives an empirical analysis with an example.     

Reconsideration on Homogeneous Quadratic Riemann Boundary Value Problem

The homogeneous quadratic Riemann boundary value problem (1) with Hoelder continuous coefficients for the normal case was considered by the author in 1997. But the solutions obtained there are incomplete. Here its general method of solution is obtained.     

Research on Tracing Evaluation System in Virtual Enterprise Based on Neural Network

The tracing evaluation index system was designed to be used in virtual enterprise and established neural network trace evaluation model. As a result, it was more simple and nicer than the traditional method, so it had wider application foreground.

一种消费者品牌偏好的模糊排序方法

为将消费者对品牌属性的模糊评判信息转化为消费者的品牌偏好信息,首先将模糊语义转化为三角模糊数,然后利用模糊数的广义加法、近似乘法及标量乘法计算,从而将消费者对属性的离散意见转化为对某一品牌的综合意见.然后通过定义一种模糊数综合排序指标来确定消费者的品牌偏好顺序.最后还通过一个算例来说明方法的实用性和有效性.
