Based on the DEA (Data Envelopment Analysis) traditional model, an improved evaluation model is introduced for the fuzzy index value and fuzzy preference weight information. The improved model is applied in evaluation of automatic testing software programs. Firstly, the subjective index values are transformed into fuzzy numbers. Secondly, the subjective preference weights are constructed as a constrain...
RS (Remote Sensing) image classification based on ANN (Artificial Neural Network) is carried out with high spatial resolution images of the wetland, which is the most important ecological environment element within the land components. Wetland dynamic change monitoring is often built upon its classification result concerned here. The typical high spatial resolution image of the wetland in Nanjing...
Based on system dynamics modeling method, the nonlinear model of the cloud computing virtual machines scheduling is built. With system dynamics methodology and the use of simulation tools, from a system perspective on cloud computing service requirements and building scale, the key factors affecting the number of cloud computing machines are identified. Furthermore, mathematical statistical theory...
