This paper proposed a new evolutionary algorithm for generating trading rules on stock market, which is called Probabilistic Genetic Network Programming (P-GNP). P-GNP represents its solutions using graph structures based on probability. It has been clarified that P-GNP works well especially in dynamic environments. In the proposed hybrid stock trading model, P-GNP is applied to generating stock trading...
With the deepening of reform and opening up, the economic development gap between several cities is widening, the imbalance in regional economic development is becoming increasingly prominent. This paper discussed the regional economic difference and regional model division by the qualitative analysis method with factor analysis and cluster analysis. Revealing the gap in unbalanced regional economic...
This paper empirically analyzes the effect of import trade spillover on the industrial energy consumption intensity, based on a panel of 32 industrial sectors for 1998-2007.The results show that research and development spillovers embodied in imports have indeed contributed to a decrease of industrial energy intensity both in high and low energy consumption intensity group in China. This paper will...
This paper proposes a new strategy β-GRA for portfolio selection in which the return and risk are considered as measures of strength in Genetic Relation Algorithm (GRA). Since the portfolio beta β efficiently measures the volatility relative to the benchmark index or the capital market, β is usually employed for portfolio evaluation or prediction, but scarcely for portfolio construction process. The...
Economic security has been a serious problem which threatens and hampers the sustainable growth of the economy. The paper sets up appraising indicator system of economic security on the basis of PSR model, and researches economic security for 21 coal cities by using BP artificial neural net. As innovation of researching economic security, BP artificial neural net has the better ability in level identification,...
In this paper, Robust Genetic Network Programming (R-GNP) for generating trading rules on stocks is described. R-GNP is a new evolutionary computation, which represents its solutions using graph structures. It has been clarified that R-GNP works well especially in dynamic environments. In the proposed hybrid stock trading model, R-GNP is applied to generating stock trading rules using variance of...
Effective customer satisfaction evaluation is an important prerequisite for power supply enterprises to win in competitive market. In this paper, we establish the power customer satisfaction evaluation index system based on previous studies. Then we prove the validity of this method through field investigations by using AMOS. Finally, path coefficient analysis is conducted to get key factors to improve...
We are entering an age of global information society (IS), which built on digital communication networks and information technologies. More and more organizations (governments, regions and cities) are using reliable data and comparable indicators of information and communication technologies (ICT) to measure information society. Considering some new ICT indicators in this digital society, we establish...
