Staff assessment and promotion models based on social assessment matrix inspired by social network

How can we explain the oriental promotion system, especially in China? It seems that the best individuals fail to obtain the positions in many cases. However, some ordinary people with outstanding performances are chosen and become more and more important in business groups. Can it be explained and can the principle be built? In this study, a set of concepts and models inspired by social network are proposed as tools which aim to be decision-making principles in human resource management. Moreover, the studies are demonstrated by simulation. However, it is only a start in this period. Some novel questions and plans are proposed for future study.
