This paper discusses in depth the different parts of the MIR-max clustering algorithm with respect to the problem of diagnosing river quality. An equivalent information theoretic measure is proposed in this paper for clustering which is based on conditional entropy. The original mutual information method of clustering is compared with the proposed conditional entropy of states given to the cluster...
The causes and prevention methods of the "bullwhip effect" in supply chain will be explored in this thesis. Firstly we will mention the concept of the "bullwhip effect"; secondly we will analyze the specific reasons of it from many aspects, and discuss the preventive measures and weakening method of the "bullwhip effect". This research can provide a theoretical reference...
