To improve these problems, a novel method combining subtractive clustering with fuzzy C-means( FCM)clustering will be advanced. In the method, the initial cluster number and cluster center can be obtained using subtractive clustering. On this basis,clustering result will be further optimized with FCM. In addition,the data dimension will be reduced through the analytic hierarchy process( AHP) before clustering calculating.In order to verify the effectiveness of fusion algorithm,an example about enterprise credit evaluation will be carried out. The results show that the fusion clustering algorithm is suitable for classifying high-dimension data,and the algorithm also does well in running up processing speed and improving visibility of result. So the method is suitable to promote the use.展开更多

This paper introduces the meaning and calculation method of EVA, focused on the analysis of the advantages of EVA performance evaluation, and also points out some limitations of EVA, in the hope that after the practice can improve continuously.展开更多

Through analyzing the factors influencing non-systematic risks of EI, the paper established a risk evaluating index system and accordingly proposed a set of appropriate risk evaluating methodology, with which enterprise can well control informationization risks.展开更多

The evaluation of Agile Manufacturing Enterprises (AME) is one of the key activities in implementing agile manufacturing. This paper proposes a method for evaluating AME, establishes a basic feature model of AME based on the feature tree and discusses the hierarchical decomposition algorithm based on the model with an example.展开更多
