In order to achieve comprehensive quantitative evaluation of plant-breeding models in the paddy field (PBMPF), we constructed a new evaluation indicators system and a comprehensive evaluation model for PBMPF. And then, we used three typical PBMPF in Hechuan of Chongqing to verify the evaluation indicator system and comprehensive evaluation model; the evaluating results were in accord with the practical...
This paper gives the model of the decision support system based on data mining and web technology. The structure of the decision support system has been improved. And the paper studies features of each module of the new system. The system makes use of the technology of the data warehouse and data mining to improve the decision-making ability, and uses Web technology to improve the efficiency of the...
The evaluation outcome often has time lags. As a result, the decision makers often make decision with time lags. In order to deal with the problem, a novel evaluation method based on Markov chain was put forward. Make the mark sequence given by experts for each index a Markov chain, the initial distribution and transition probabilities matrix can be computed based upon the statistical analysis of...
