On Fuzzy Ideals in BCH-Algebras

Fuzzy Information and Engineering (2007)

Wang Feng-xiao

The aim of this paper is to introduce the notions of fuzzy quasi-associative ideal and other fuzzy ideals of BCH-algebras and to investigate their properties. We give several characterizations of quasi-associative fuzzy ideals and closed fuzzy ideals. The relations among various fuzzy ideals are discussed as well. Finally, we characterize quasi-associative BCH-algebras via fuzzy ideals.

On Combination Forecast of Weighted Geometric Means Based on Arithmetic Average Approach

Journal of Southwest China Normal University (2013)

Wang Feng-xiao

Combination forecast of weighted geometric means is a model of nonlinear combination forecast.Based on arithmetic average minimum approach,the combination forecasting model of weighted geometric means is proposed and discussed.The concepts such as non-inferior combination forecast,superior combination forecasting and redundant degree have been put forward.Under certain conditions,the existent conditions of non-inferior combination and superior combination forecast have been discussed.Some theorems which determine whether a method is a redundant forecasting method have been given.Application example shows that this nonlinear model is effective.

Multivariable non-equidistance GM(1,m) model and its application

Systems engineering and electronics (2007)

Wang Feng-xiao

For multivariable non-equidistance sequence,a grey forecast model GM(1,m) is established.Based upon the exponential trait of the grey model and the definition of integral,a construction method of the GM(1,m) model's background value of multivariable non-equidistance sequence is put forward.Moreover,the GM(1,m) model's fitting precision and prediction precision are advanced and the scope of application is enlarged.As the application,a forecast model of growth level of China countrysied teenagers is established.By the realistic example,the result is proved to be precise and reliable.

Combination GM(1,1) Power Model and Its Application

Shuxue de shijian yu renshi (2011)

Wang Feng-xiao

GM(1,1) power model generalizes the grey Verhulst model.Since the initial conditions affect the accuracy of the model,the average relative error function is seen as functions of power exponent,development coefficient and grey action.The ant colony algorithm is used to solve the models parameters based on the average relative error function minimization. And then the GM(1,1) power models are established,according to these GM(1,1) power models,the combination GM(1,1) power model is present,and the combination weights are determined using the maximum relative error minimization and particle swarm optimization algorithm.Then the effect of initial condition is overcome.Finally one example shows the precision of the combination GM(1,1) power model is higher than the GM(1,1) power model. So this method is feasible,effective and has important theory significance.
