We evaluated the projects risk by using the Back Propagation neural network model, then set up the risk evaluation indexes of enterprise credit guarantee projects. The training samples, verification samples and testing samples that the model needed were generated by the randomly get arms method in the range of single-index evaluation standard. The case study indicates that the methodology for generating...
In this paper, we propose an index system to measure enterprise R&D funds management capability, use factor analysis models to define the main factors which determine the impact of corporate R&D funds management capabilities. This system is used to empirically analyze R&D funds management situation of medium-sized enterprises of China from 1991 to 2007, and provide them some effective...
The situation of gas flow distribution in burden surface ensures to a certain degree whether the blast furnace could be running in a way of high efficiency and low consumption, and then influences the economic benefits of the whole steel enterprises. Focusing on the difficulty of directly detecting the gas flow distribution in burden surface, a method of that distribution is designed in this paper...
Builds a GM(1,1) grey forecasting model to find out the fluctuating trend of the historical data series, then builds a Markov transition matrix to find out the transition probability, finally combining these two models to forecast the power requirement accurately by the historical time series data.
In this paper, the city input-output efficiency analysis which includes electric power input has been done based on the extension models of DEA to Chinapsilas typical cities. At first, it established index system of comprehensive evaluation of city efficiency, and did input-output-effectiveness evaluation which include electric power input for China's 23 cities in 2006 and sorted by the urban development...
