By considering the characteristics of agricultural products prices such as great fluctuations, nonstationarity and nonlinearity, a BP Neural Network model was designed for forecasting and verified by real data from some agricultural products wholesale markets. In order to improve the prediction accuracy, a combination model of BP Neural Network and time(More)
As the population of university students grows every year, more and more attention is paid on the dining problems at university canteen and therefore the service quality of a university canteen plays an important role in building a university's reputation. In this paper, the customer satisfactory rate of the canteens at South China Agricultural University(More)
Probability rough set is applied to product model selection, risk type decision making problem is converted to probability rough set model for analysis, further, minimum risk decision making rule is found. Take a furniture factory in Foshan City of Guangdong Province as an example, this model is applied to furniture color selection, as provides a scientific(More)
—Electronic-nose was used on detecting the pernicious gases in piggery. The feasibility of improving the electronic-nose recognition model by using a feature extraction method with wavelet transform and genetic algorithm(GA) was discussed by aiming on cross-sensitivity of gas sensors. The experiment result shows that, the feature samples extracted by the(More)
